The complete and utter idiots guide to 3D printing in resin for Wargamers

I’m terrible at printing, I can’t level a bed to save myself, I need a raft whenever I print in FDM, yet I still manage to get decent prints. This is through trial and error, and spending way too much time on Facebook groups, reddit and every blog I can read. I’ve recently taken the plunge into 3D printing with DLP resin using an Anycubic Photon. This post will cover what I’ve learned through failed and successful prints, while trying to achieve the holy grail of prints that work every time (60% of the time). The post will assume that you have the same or a similar printer, and some software will be specific to the Photon (which is currently the most popular entry level resin printer) though generally the concepts will apply to other similar printers.

Why Resin?

Most people will start with FDM printing, and I’d definitely recommend starting that way. It’s cheaper, safer, cleaner and in my view easier for the uninitiated, there is also a lot of information out there to get people started. Often people will ask whether they should get a FDM printer or resin printer, in my view you should aim for both, starting with a cheaper FDM printer. There are plenty of things I wouldn’t print in resin due to size and cost of printing, such as 28mm tanks and terrain pieces, while there are other things that I wouldn’t dream of printing on FDM where resin is far better suited such as figures (I realize that people do print miniatures on FDM, but for the average person it’s really not worth the effort compared to the outcome) and gaming pieces at smaller scale (such as those suitable for games like Epic 40,000, Flames of War, Team Yankee, Cruel Seas or Micro Armor).

Resin printers can produce far more accurate, higher resolution prints, with easy to remove supports making them ideal for small, high detailed printed items. Based on my experience they are definitely worth the investment if you are a 3D printing, wargaming hobbiest, but they do have a very steep learning curve. The final result is definitely worth the effort:

Making sure you have everything your need

First, resin printing is way different to FDM. With FDM all you need is a printer, filament, a scraper, files, slicer and maybe some hairspray for bed adhesion, plus any tools for cleaning up your prints. Resin printing is a far different (and messier) beast.

Here’s what you’ll need to print in resin:

Choosing your printer

I decided to purchase a printer over Black Friday week in 2018, and in the end I came down to a shortlist of 3 3D printers:

  • Anycubic Photon: USB operation for files, uses proprietary .photon files, slicer (which is rebranded version of Chitu, with very little options) works with mac or windows, compatible with chitubox (far superior to what comes with printer) software. Better quality build plate than D7.
  • Wanhou Duplicator D7: USB operation for files.
  • Creality3D LD-001: Has wireless and ethernet functionality and automatic bed leveling. Reviews suggest problems with the slicer

2019 Update:

A lot has changed since I first posted this, the following similar printers are also now on the market:

  • Anycubic Photon S: Very similar to the original Photon. USB operation for files, uses proprietary .photons files, slicer (which is rebranded version of Chitu, with very little options) works with mac or windows, compatible with chitubox (far superior to what comes with printer) software. Upgraded dual Z Axis guide prevents Z wobble.
  • Elegoo Mars: USB operation for files, uses Chitubox (which works with Mac or Windows)
  • Epax X1:Uses Chitubox (works on Mac or Windows), supports Anti Aliasing, Double Steel Rod reinforced Z Axis gantry.
  • Longer SLA: Uses proprietary “Longer” software which seems to work fine on Windows, but may have issues with Mac
  • Monoprice MP Mini: Auto level build plate, needs firmware update out of the box, Web UI + Creation Workshop & Print Studio software support, magnetic build plate, can print over the web or use a Micro SD card.
  • Phrozen Sonic Mini: Uses CHITUBOX slicing software, has a mono-LCD screen. Phrozen recently released a Sonic Mini 4K, which has been getting excellent reviews with regard to print detail (obviously a high priority for miniature printing!).
  • Sparkmaker: Uses SD card and spark studio for slicing, has potential to be one of the better budget printers out there, but if given the choice would still go with a photon due to the massive amount of support online.

In the end I went for the Anycubic Photon, the reason, it had the most active Facebook group, slicer that worked on a mac, and didn’t have any major problems that I didn’t feel that I couldn’t overcome. It also helped that there was a $70 discount applied at checkout when I purchased it. What you get is up to you, but for now the Anycubic Photon is probably the best option – I still think this to be the case in August 2019.

Slicing your files

For those of you used to FDM printing, you will have used a slicer such as Cura to create your Gcode files from STLS. The process is similar with resin printers. The Anycubic photon cones package with this own port of Chitu, which I’m not a fan of. If you are wanting something a bit more powerful, check out Chitubox which can be found here, while it’s support group can be found here on Facebook.

The Angle of the Dangle and a little bit of Suction

This was *supposed* to be 3 stuarts, not 1 hull and a bunch of cured goop!

Printing with resin is far different to printing with Filament. Firstly, the build plate is at the “top” of the print, which is lowered into a vat of uncured resin, which is cured layer by layer with a UV projector as the build plate raises up on it’s Z axis. As it does this, the resin has a suction effect that pulls at the print and can result in a failed print if it detaches from the bed, and cures to the FEP at the bottom of the vat. This can be avoided by using more aggressive supports as well as angling the print. Personally I’ve had success (and failure) with both vertical and angled (people recommend .45 degree angles) prints. If you are running into failed prints, this is something you’ll need to consider, though personally I think having strong supports makes more difference, at least when printing tanks and the like.

Another reason to consider angling your prints is due to the placement of supports (which I’ll get into further into the article). Supports are placed wherever there is an “island” (effectively an unsupported part of the model perceived from the orientation of the build plate. These need to be removed and can require sanding or filling if there is any chipping, so ideally will be on the back or undersides of the model. You can ensure this but angling the model in such a way that the back is facing the build plate making for easier support cleanup.

For 15mm vehicles where there are lots of flat bits and sanding won’t damage details I’ve found I’ve had the most success printing vertically, which also allows me to average about 4 turreted vehicles for WWII per print, while for figures, I’ll always angle to minimize the amount of supports needed on the front facing parts of the miniature.

Hollowing Prints

Resin for 3D printing is expensive, and while I personally prefer the weight and feel solid prints, I still hollow most of my AFVs as it saves a significant amount of resin, making them even cheaper to produce, it also means you are less likely to need to fill up the vat multiple times during a print, something I learned the hard way.

There are multiple ways of doing this, and the stock slicer that comes with the photon does not support the hollowing of prints. If you want to use the stock slicer, the best bet is to use a piece of third party software such as Meshmixer, which can handle the heavy lifting as outlined on this Makers Muse video:

Personally I prefer an all in one solution, which means I’m using the powerful Chitubox Software. It’s still a work in progress, so don’t expect it to work all the time (something you should be used to now with 3D printing) but now that I’ve got the hang of it, I seem to have no problems. You simply select the models you wish to hollow and click the “hollow” option to hollow out the model. This will hollow out the model according to the settings you select.

You then want to ensure that you include some vent/drainage holes on the underside of your print to allow a) air to flow which will help resin drain during printing and b) to allow uncured resin, IPA and/or water to drain out in the pre curing process. Ideally you should make these holes as big as you can get away with without damaging the model, I usually start at around 8mm for a 15mm scale tank with multiple holes in the base of the hull, and 4mm for the base of the turret (sometimes I can fit two holes in there). Ultimately the more the better when it comes to having a clean model for curing. I don’t use plugs to fill the gaps in, as I hide mine in the underside of the model, so you can safely delete these plugs most of the time.


Generally you’ll be printing highly detailed models on your resin 3D printer and the vast majority of these models will require some sort of support to ensure that they print is successful. Supports are required to allow the parts of the print that do not have a direct connection to the build plate to print. The good news with supports with Resin V FDM printing is that they are far easier to remove than what you would be used to with traditional FDM printing if done correctly.

When I first started using my printer I found I was constantly getting failed prints, where the model would break off the supports and cure to the FEP plate, ruining the print and requiring cleanup of the plate, filtering of the resin and starting over. After a fair amount of troubleshooting I found that this was due to my support settings, which as default in Chitubox aren’t sufficient.

Since then I’ve beefed up my supports to the large model settings shown in the video before, to what I consider is probably an overkill, but it’s given me a 100% success rate so far. For those interested in my support settings for Chitubox on an Anycubic Photon, they’ve been copied 100% from this video:

These break off easily without damaging the model, but they do require cleanup afterwards as they leave small “ball” shapes on the model which require filing. I feel this is far superior however to supports that potentially chip the model itself. Soon I’ll test out the small model settings, which I think will also work well, and result in less cleanup.

By using these settings, you’ll get a good success rate simply by clicking “+All” and having the supports auto generate. 9 times out of 10 they will put them where needed to print successfully, though more experienced users will often do this, then add or remove supports manually to ensure success, for instance, in the “settings for small objects” image above, there is are still multiple islands that are missing supports, such as around the loincloth, and the guard of the sword, which will need additional supports.

You can learn more about supports and resin printing here. A useful tool, the photon file validator can test for overhangs available here.

Getting your settings correct

Each brand and color of resin is going to be slightly different, and require different amounts of time to successfully cure. It’s worth checking Facebook for a user group for your printer to find out the optimum time for curing each resin. Eventually slicers will have this information pre loaded, but that’s a long way off. For the Anycubic Photon, use this link for the latest, updated guide to resin settings:

Also search out any repositories for useful software, FAQs etc, such as that for the Anycubic Photon at the Photonsters GitHub here.

Bed Leveling

As with FDM printing, bed leveling is essential to a successful print. Unlike FDM printing, this is usually set and forget and if you’ve done it right, you should not need to adjust it unless you are doing significant maintenance on the printer. I’m fairly confident that I have never leveled the bed on my Monoprice Maker Select V2 correctly, which is why I’m still printing on rafts, 7 months after getting it (thought I think it will be easier now I’ve moved to 3 point levelling, but thats for another post), with the photon, its simply a case of getting the plate to a point that it’s flat with the glass, about a paper width gap (enough for the FEP plate), and then tightening up a screw, as per the below video:

Cleaning Up & Curing

Where resin printing differs from FDM printing the most is in the cleaning up process. With FDM it’s simply a case of popping the print off the built plate with a scraper, removing any supports with pliers, a knife and a dental pick, sanding a bit and then spraying with filler primer before painting, with resin, it’s slightly more complicated, but worth the effort. To clean up a resin print you will need to:

First you’ll need to take the build plate out of the printer. Put on gloves and safety glasses first. Usually I will have a plastic plate with paper towels on it, I will place the build plate on this and use a plastic scraper to remove the print.

Once removed use tweezers or something similar to transfer the print into a jar or container fill of 95%+ Isopropyl Alcohol and leave for about 5 minutes, then give it a good shake to clean off any uncured resin.

You’ll need to then remove the print from the container, making sure you allow the uncured resin and IPA to drain via the drain holes if the object was hollowed. I then sit it down on some paper towels to dry off.

The next step is optional, but you may chose to transfer it to a second tank of IPA. This means you have a Step 1 IPA tank (this gets dirty fast) and a Step 2 tank (much cleaner). Repeat the process of soaking and shaking, before a third, optional step, of transferring it to Water and giving it a rinse. I’ve stopped doing this recently as Ive found that it can leave a white residue on it, and instead I leave it to dry on a paper towel.

Now you will need to wipe down your build plate and plastic scraper. I use the blue shop towels to do this, as it does a far better job of cleaning than any paper towels. If required, rinse the scraper in IPA. I then store my scrapers in a sealed tub, to prevent any chemicals from getting anywhere on my desk.

Once dry, you’ll want to take your clipper and remove all the supports. It’s far easier to do this while the resin isn’t fully cured. Dispose of this uncured resin in the same trash alongside your disposable gloves, paper towels, etc. if possible, attempt to cure any resin before disposable.

To cure, you’ll either leave your print out in sunlight, or for those of us with winter, under a UV light source.

Print Failures

Its inevitable that you will screw up prints, especially at the start. Usually this will be due to incorrect support settings, or curing settings for a new brand of resin. If this happens you’ll need to scrape the cured resin off the FEP plate, drain the vat and filter into an old bottle of resin. The cured parts along with the filter will then need to be disposed of following correct safety procedures. Wipe down everything, ensure that all settings are correct, and then pour the filtered resin back into the vat ready to start again.


When you print with FDM printers, the biggest risk to your safety is fire, which can be mitigated reasonably easily with smoke alarms, fire extinguishers and the all important Mosfet mod. With resin printing, its a whole different rodeo, as now you are dealing with a bunch of potentially toxic chemicals and fumes. It is extremely important that you follow proper safety procedures for the handling of uncured Resin, IPA and other chemicals as per the video below.

If you have pets (or children), it’s a good idea to ensure that you have a sealed trash can to prevent them from getting in contact with it or ingesting anything. Make sure you always use nitrile or other chemical resistant gloves, and use safety glasses – resin and IPA aren’t nice on your skin, or eyes.

Don’t tempt fate by setting up your printer in a room with carpet. If possible have it on a wipe clean surface such as plastic or stainless steel. If if gets on fibers it won’t come off, and they will need to be disposed of. I learned this the hard way when I got it on a neoprene paintball tech mat.

How to make a DIY UV Curing Box

If like me, you experience winter, putting your models outside in the sun to cure simply won’t be possible. Luckily there are plenty of cheap sources of UV light available online. Make sure that it meets the requirements for your resin. There is one sold by Creality 3D with a solar turntable that works well, but you can also use nail polish lamps are great, others use UV strips and buckets, or a combination type approach as per below.

So there you have it, my idiots guide based on what I’ve learned so far. This is a continual learning process, so expect this to be added to and expanded on as I make horrible mistakes, and learn how to fix them in the process.

    thank you for this great article. It was the reason for ordering an Anycubic Photon yesterday.

    As a rookie to resin printing I have a question about your print settings in chitubox. What settings are you using for your green resin? Your results are looking so great!

    I read a lot of articles about and came to this result (with more questions than answers):

    Layer Height 0.04
    Bottom Layer Count 8
    Exposure Time 10
    Bottom Exposure Time 50
    Light-off Delay ?
    Bottom Light-off Delay ?

    Thank you for your help and best regards,

      Hi Andreas,

      I only use the green anycubic resin, because I’m too lazy to change any of my settings. Here is what I have on Chitubox:
      Layer Height: 0.05
      Bottom Layer Count: 8
      Exposure Time: 10s
      Bottom Exposure Time: 50s
      Light off Delay: 1
      Bottom Light off Delay: 0 (I’m unsure if this is what I should be using)

      Use this as a guideline for any resins:

      I strongly suggest joining the Anycubic Users group on Facebook, thats where I’ve done all my troubleshooting – whenever I’ve screwed something up, and I’ve done it a few times.

      So many folks are purchasing these after reading the blog, I really should throw in an affiliate link haha!

      • Andreas says:


        thank you very much for your help. Much appreciated!

        You really should post a “buy it now” button in your article 😉

        People who are planning to print little tanks want’s to hear from other tank printing people that it will work. So your settings and experience are more valuable than from any other users printing something else.

        I’m looking forward to my new printer to test if everything will work. The bad thing is I will have to replace my FDM tank collection by resin models now… 😉

        Thank you again for your help and best regards,

  2. Jon Vogel says:

    Nice article. Your ChiTubox support settings for heavy objects shows the Bottom settings twice and doesn’t show the Raft settings. Could you please correct this?


  3. Maxiride says:

    Great article, I’m getting into resin printers too.
    Would you mind elaborating why you would still suggest the Photon in August 2019 over the Photon S or the competitor Epax X1?

  4. Manuel says:

    Hello ! Is there any way that you can upload a better resolution picture for the small objects settings ?
    I see that you say it’s in the video, but I watch it and didn’t see anything like your’s 🙁

    Thanks in advance for your answer !

  5. Lee says:

    I have a question? So I have marks and small hole in my model after cleaning the supports. What’s the best way to deal with them? Sanding them or filling them in

  6. Brian says:

    I just got a resin printer and am planning on printing 15mm tanks with it. I have made 1 test one and it printed great but I was wondering how safe it is to hollow it out. I am unable to cure the inside. Will it dry out in time? I am using Elegoo Grey but was wondering if a clear resin would cure in UV on the inside through the clear walls. I have searched but people mainly just talk about hollowing out models not so much in the curing or safety aspect. I don’t want to risk using miniatures that people will handle if they are toxic. Sorry for the noob question just want to be sure

    Great Info thanks.

  7. Pamela says:

    I am using the Longer Orange 10 SLA printer with white Anycubic 405nm resin. I have sliced my print job in the Longer software and my print did adhere to the plate but it was not detailed. Then I sliced using Chitubox and my prints have not adhered to the plate and seem to have only cured an outline of my print at the bottom of the vat. I am super frustrated and just want to know what direction to set up my job in the slicing software and exactly what the settings should be for a successful print. Please help me.

    • Wargaming3D says:

      Hi Pam, I can’t comment on the Longer, as I’ve never used one – but they *should* be fairly similar to the anycubic photon. My experience is failures are involving 3 things: 1) Levelling of the Bed 2) Incorrect Resin Settings or 3) Undersupporting. Without seeing the files and the example of the fail its hard to tell. I’m going to guess though, that seeing it’s cured, you’ve probably got ok Resin Settings, but because its curing on the vat, that your bed isn’t levelled properly – but thats only a guess.

  8. Mortezo says:


    first of all thanks for this guide, it is so far the most detailed one and I found a lot of helpful ideas.

    Unfortunately I do have a problem with the chitubox, after set up everything as on the video I always end up with auto suport making a wood that will be impossible to remove.

    Any ideas what I am doing wrong?

    Cheers guys and happy printing.


  9. Edwin Barreto says:

    Fortunately, as a newcomer to resin printing, I am quite grateful for this superb easy to understand article that provides the learned wisdom and the expertise I sorely am in need of. Every 3d printer vendor should include this as part of the package. I am very grateful for Wargaming3D for such vital educational lessons. Thank you!!

  10. Richard wilson says:

    I just got my anycubic photon s 3d printer today . I ran 3 prints and they all came out perfect amazing . I,m having trouble i don,t know how to save prints from chitubox to thumb drive . When i take thumb drive to the printer all i see is 4 empty boxes . The thumb drive is lit up . This is my first time 3d printing i need step by step help on the software part all the youtube videos got everything else except how to transfer files to the thumb drive . I know its something easy that i,m not doing but i need help in a major way. Please give me step by step instruction on how to transfer files from chitubox to the thumbdrive . And please direct me to any videos out there on the subject if any . Thank you all for time and patience in helping a newbie come on board to 3d printing. God bless you all.

    • Wargaming3D says:

      Hi Richard,

      I wrote the article for the original version of the Photon, had a friend buy one last week and there are now 3 versions of the firmware, and 3 different file types. It will depend on your firmware whether it supports chitubox (.photon and .photons), if it doesn’t (.pws) you can use chitubox and save and then import the .photon or .photons into the softwre that comes with the photon and resave as .pws and it will work. Not ideal, but its a short term workaround until chitubox supports the new file format.

  11. Mae says:

    new to 3D printing I took a 3D modeling class in college but I’m having trouble understanding what to do or even how to get started really. I’ve been using things verse to find things to try printing but I would really love to make some of my own things. Any tips on where to start? I’m becoming very over whelmed by all the things that come up and haven’t touched my printer now in months.

    • Jonathan Cox says:

      Hi Mae! You’re absolutely right in that there’s a ton of options when getting started. The first thing would be to figure out what you want to make, and figure out what software is the best choice for your goals and your budget. For character work, a lot of professionals use ZBrush, though there’s a huge Blender crowd as well. For hard surface models, a lot of folks use Maya, Blender, Fusion 360, etc. After you choose, look for some resources to help you get started. Sites like Udemy have some great resources available, though you can also find a ton of great material for free on YouTube. Finally, there’s a Facebook group that’s dedicated specifically for folks that want to learn 3D modeling/sculpting specifically for 3D printing. You can find that here:

  12. Winter says:

    Hi, I’m thinking about buying a resin printer but I still have some (admittedly little) details I’m a bit unsure about, mainly the cleaning of the printer/vat.
    How long can the resin stay in the vat? I already have an FDM printer sitting here so I know that I’m unually not the person who whips out a print every day or every other day, but rather prints several things for an objects and then pauses, sometimes for a couple of weeks. Of course in that case I’d empty the vat and clean it, but if it’s just a few days, would it be okay to keep the resin in the vat or should I remove it?
    Which leads me to my other question. I found out that microfiber cloths are usually the go-to for cleaning the vat, but most people just throw them out if they get too dirty. I have to admit this feels a bit wrong, consindering the huge waste problem the whole world is in… Anyway, I was hoping to find out if there’s a way to clean and reuse microfiber cloths or if this isn’t recommended/sustainable? Thanks!

    • Jonathan Cox says:

      Hi Winter,

      For the question regarding resin, as long as you don’t have a print fail (which can leave pieces of solidified resin at the bottom of your vat) and your printer isn’t somewhere that gets a lot of sunlight, you can leave it in for quite awhile. I leave resin in the vat for weeks at a time without issue. That said, you’ll want to give it a good stir before you use it as it does have a tendency to separate a little.

      For cleaning, I end up using paper towels, which is a bit wasteful. However, given the fact that I almost never remove the resin from the vat, I’m not usually using that much. Also, before just throwing stuff away, you’ll want to make sure the resin is cured. I leave the paper towels I use out in the sun before tossing them, as throwing away uncured resin is a really bad idea. I hope that helps! =)

    Thanks for publishing this for complete and utter idiots like me.

    Just to let you know, the link to the Anycubic Photon spreadsheet is broken. Someone sadly deleted it.

    I used to love that thing, and made a project similar to it that allows people to share their settings. Would you consider linking to that one instead?

    Your article ranks quite highly when someone googles wargaming and resin, so I’d hope that we could get more people aware and contributing to it. I don’t make any money off of it, I just think it’s something great for the community.

    Anyway, thanks a lot for the article
