WWII French Laffly S15T Artillery Tractor at 1/100 scale for resin printing

This was amongst the first of my big design requests back in September 2020. A client wanted a very historically accurate vehicle at the 1/28th scale, a model with a very detailed subframe. Given I only know how to use MS 3D Builder this was something of a design saga. This listing provides you with files to RESIN print this model as the 1/76 scale.  If you want to print this model in a larger scale buy the scale specific listings that I will be making available. They are all slightly different and have been worked on in order to give what I hope are the best results at that size of model.

French Laffly S15T Artillery Tractor 1/100 scale. Though originally designed at 1/28 I have reworked those files for the 1/100e. This has meant "hardening" some parts to still be viable at this scale and merging some parts into a more consolidated form so that delicate parts become supported by the larger. The delicate window screen & wipers have had to be incorporated into a a very thin solid screen now permanently attached to the hull. All wheels are also now printed with the hull not as separate items.

The model has been test printed by me on an Elegoo Saturn 8K printer. Using the basic settings and a layer height of 0.05mm. I include the pre-supported files that I used in the test print so you should get a reliable print. The clean up was reasonably straight forward. I use water soluble resin and clean it in very hot tap water. I did need to use a sharp knife to remove some supports that were running close to the model. So pay attention in cleaning before you cure the model. I was able to remove supports reasonably easily from the detailed subframe with out damaging any of the hydraulic parts. Just take a little care in this part of the process to enjoy the best results.

The models consists of the following files:

1. The vehicle complete as a single piece with the option to print with a driver or without.


2. Though I have hardened the front headlights I have included a file to create repair lamps as needed.


3. A steering wheel on column is include for use when using the vehicle without driver.


4. Driver with Steering wheel & column. Be sensitive when removing the supports.


5. Passenger open hands. Add a greenstuff map and he will be useful in the front passenger seat.


6. Passenger with a wine bottle. Just be careful of the top of the bottle when removing supports.

This model was designed by Neal Bowskill copyright September 2020; printed versions of this model have been available since this date on Ebay and has appealed to those who like niche models. This single piece 1/100 scale model has been reworked from my original file May 2023.
