Happy Father's Day!
I bought a flash forge Foto 6 for 160.00 on Amazon.
It prints uv photo polymer.
Fill up a cat and it builds ar the storm lifts.
Polymers are ~ 35 to 45 per 500g you can print a **** ton of small parts.
Typically they use an alcohol clean up liquid but they also make a water washable.
There is a manufacturer, Anycube, they make a material called "Tough" that is flexible enough to take a screw. There are also rubber like polymers.
Only thing is you can't see it build.
It uses an LCD to mask each slice from a UV light.
