Re: Jumping into 3D printing from CNC

That's an amazingly helpful analysis -- thanks. I hadn't even considered layer adhesion versus lateral stress, but after reading your explanation, I can see that it's going to be a major issue in a number of the use cases I was contemplating.

Re: Jumping into 3D printing from CNC

Also, dual-material support is a pain in the butt. Don't approach the process anticipating you'll use it successfully. It is far, far better to print multiple pieces and assemble them afterwards. That's very helpful information -- thanks. Dual-printing with support materials was the main considerat...

Re: Jumping into 3D printing from CNC

Thanks. Have you had occasion to CNC mill 3D printed parts? For example, if you need a part with a cylindrical extension that needs to be close to exactly 1/2" in diameter to fit a bearing, would you try to 3D print it at exactly 1/2", hoping that the print tolerance would be good enough, or would y...

Re: Jumping into 3D printing from CNC

Thanks, guys. The main reason I'm interested in the dual extruder design is to print with support materials. Are there limitations on which main materials work with particular support materials?. E.g., Can I use PLA with ABS, nylon, or C.F. filament?

Jumping into 3D printing from CNC

Hi --I've a fair a mount of experience machining parts with a heavy duty CNC machine. I want to/need to get a 3D printer to augment my capabilities but am at the bottom of the learning curve. I think I've settled on a filament-based, rather than resin-based, machine. I've done some research on the F...
