What do you mean by no real prospect for the parts?
To my understanding, SLS is really the only way to print with metals and high variety of materials, which although wont be as reliable or strong as injection molds, should still show a significant increase in options for what you can do with the parts.
I know the first concept printers will have a hard time getting precision and strength down right away, but are still important nonetheless.
Please share your opinions on the results youve found so far! I know it must be really tedious, but the feedback from the community should be really good for keeping projects like this in motion, everything learned and shared is still progress. ^^
Thank you for your efforts!
