This is an initial Idea so I just going to throw it in the air.
Do you think is possible to use a FDM 3d printer to make molds for Methacrylate Casting?

I have read of Methacrylate Casting using molds made on SLS printers, but they are very expensive.

I know the problem here is finding the right Polymer to do the job, do you think some of the Taulman's Nylon could work?

Best.

Jaime.

Just apply a thin layer of it and let it dry.

Hey oklok,

Thanks for the reply. I've since moved to using a garolite bed for my nylon prints and have had awesome success with it. If anything they stick too much, for larger prints I've put strips of blue painters tape down to help me release some of the prints. My printer is in storage at the moment though until I can move into our new house and get my workshop set back up.

No problemo!

The problem with nylon is it doesn’t stick to the plate easily. So to solve this you can buy garolite bed to solve it. And if it sticks to much then maybe you lightly sanded it to much improve the adhesion. Try smooth it out a bit somehow, then maybe it wont stick so much.

Pretenda, maybe you should use Kapton tape to solve it!?

Makes it much easier to pint.

Ron, Thank you. Yes she is enclosed. Whats max setting for stock hotend 210 in RH right? As for flowrate how do i calculate how much I should increase it? I assume you mean the slider under the manual control tab in RH.l It's at 100 right now. Do you guys print at lower heights with nylon? (.2 as apposed to .3)

Sorry for all the questions. Thank you!

Changing your extrusion multiplier(in slic3r) will increase flowrate. Just try a little at a time.

I print my nylon layers at .25-.3mm

The real key as ronsii said was that you need more heat to really get the most out of nylon.

Sorry for all the questions. Thank you!

If not you might think about making something as it does help a bit.

The problem with nylons is you really need more heat than the stock SD hotend can give safely for maximum adhesion hence the reason most people that use nylon have gone to the E3D or similar.
