Very impressive!
Well,what I would make?Anything,as long as I can use them in my scalemodels.But dimensions of the parts need to be exact,how about that ?Sintered materials are always better than pewter,never mind the colors ,I'll paint them anyway.
Comes to mind , fanblades (jetmodels) , more accurate tracks for panzermodels (specialised scale model brands sell them at extreme high prices.),landinggears,more detailed helicopter rotorheads.....hell, even a complete model!( no more cyano -acrylic glue !)
About the knowledge ,do you have it "in d'a house"?( I have some experience with injection and vacuum moulding,spend 15 years as a technician in industrial environment,and maybe ...maybe I can help with finding some better priced basic materials,my " old man" is (still) active in recycling branch (sales) but this depends on your location (transport!!!) and this ain't BS,mind you)
And last but not least,would you accept drawings made in other software (CAD)send to you by mail?
@ Jupp, you can bet you're butt that these materials are robust,when you drop pewter parts THEY GET DENTED( very soft material) ,not good, and no moulding seams.
One problem though :pricing, cause it's not mass production.( BTW Got here through Blender nation)
Well ,that's all folks, good night and PEACE bro's!

Well Z..Lace,are you familiar with sintering?To use this procedure for mere brackets is way to expensive,On the other hand prototypes could be done ,BUT don't exept to make chipsets with it ,PCB are doable ,and offcourse HEATPIPES (YES ) depends on how advanced their 3D printer is , And ,to be honest , for stuff like that ,traditional chemical milling ( = photo-etching ) is a better way ,but not healthy ( uses acids e.g HCl) used to make PCB for guitar effect pedals
There' s always the fact of the material combination and the temperatures not to mention the expansion and shrinking,off course .This is becoming an interesting thread! Cheerio.
