Carlos & Thomas,

I also posted this in my Facebook Group. Richard Humble (RichH on LAF) pointed out that the Kickstarter vehicles I am printing could be optimised to use about 20% less resin by reducing the supports and thinning the walls to 2mm or even 1.8mm. That would bring the costs down by probably 15%.

One of the things I didn't say is that 3D printing allows you to have vehicles that are not easily available in 1/50th scale such as the M132 Flamethrower, M106 Mortar carrier and M577 Command vehicle.

Indeed it does and furthermore you can change the models quite a bit when you take the time to get involved in 3D sculpting programs. My firest try was with Tinker CAD , very easy to learn.

Rich is quite right there. At least the main parts of the AFV are hollow which reduces cost as well. The first thing I do is to make stl designs hollow before printing. Just make sure to leave drainage holes.

Following advice from Richard Humble and Robert Pye, I have done more experiments and have recalculated the costs of the 3D vehicles.

Here is a print from the Bob Mack Kickstarter. I printed two M113 with tracks, cupola, Machine guns etc. The models weigh 208 grams and the supports weigh 202 grams. For some unknown reason, I appear to use 30% more resin than the weight of the parts produced. I also recalculate the alcohol and got it as 10% of resin cost.
So, a 1/50 scale M113 ACAV with extensive supports costs about £9.50 in consumables.



I then took a free STL of an M706 Cadillac Gage commando and printed it horizontally at 1/50 scale direct on the bed with minimal supports. The wheels and chassis are separate solid parts.  I made the model hollow with 1.8mm walls and a drain hole. This weights 99 grams and the supports were about 5 grams. This cost £5.20 in consumables. Note that this is a V-200 rather than the V-100 that was used extensively in Vietnam.



Richard Marquis sent me an STL for an LVTP-5. I printed it horizontally at 1/72 scale direct on the bed with minimal supports. I made the model hollow with 1.8mm walls and a drain hole. This weights 116 grams and the supports were about 5 grams. This cost £6.00 in consumables. There is a print failure on the front track sprocket where I forgot to add supports.



I looked at some stills from Apocalypse Now and resized the Cambodian Temple Lions. These are hollow and cost £ 0.95 in consumables. I also found a Naga sculpture.

Impressive 3D printing!  :o

Indeed, they look very clean and well detailed. All looks way beyond my technical ability though.

I agree, but beyond my technical ability as well.

Thank-you everybody for the kind comments.

Richard Marquis sent me an STL for an LVTP-5. The original file is about 1/50.

I printed the LVTP-5 as a single piece at 1/56 scale as that is the biggest that would fit on the Anycubic Photon Mono.
The vehicle was set at 60° to the base plate. The model was hollow with drain and vent holes.
The final model weights 216 grams and cost £11.40 in consumables.

Even at 60 degrees to the baseplate, the model only just fits into the Anycubic Photon Mono.
Here the bath has been removed so that you can see just how tight it fits.



Here the model has been quickly sanded and sprayed with Vallejo Russian Green. The figures are Empress.

Very good printing. You reach a printing quality that is superior to my company's FabLab where I printed mine. 1/56 scale makes the job very well. That is good to see 3D for real again.

Dear Richard,
Thank-you very much for the STL.
I am using an Anycubic Photon Mono, which arrived nearly two and a half weeks ago.
I have had a steep learning curve but I am gradually understanding how to do this.
I will do the Otter soon.

That looks so much smoother than the FDM thing I bought, good job.

Dear Ash,

If you go to page 2- November 5th, you will see a FDM print of a waterline LVTP-5 from Bulter's which looks like it was hewn out of pine by a drawf with an axe.
Resin SLA printing is so much better.
