Food safe coating material for 3d printed objects(?)

by DukeMagus

I got a question:

Which COATING material you can use in plastics to make it food safe (to use as a mold for things like chocolate and other stuff with low melting point)

Before you say PLA or PETG are food safe plastics, the process the plastic itself passes is dangerous (normal extruders can have lead in their composition, the plastic isn't always 100% clean or pure and the extrusion can increase the chance of small bits of the part "falling off" and gluing on the food).

Some people said Shellac is a food safe material, but that's made from bugs! Another alternative is to purchase food safe silicone, make a plastic piece and use it to make the silicone mold, but that method is overly expensive and takes up to 24 hours for a piece to completely dry!

So... the coating material should:

  • Be food safe
  • Have a melting point above 100ºc (even better if it's above 150ºc. it won't go to the oven, but molten chocolate is hot!)
  • Attach to plastic
  • Have no "unhealthy" properties (rusting, attracting too much bacteria, etc)

Any suggestions?

MGN12 ball size

by jarvis32

I recently ordered mgn12 from banggood and found missing balls. There was no backlash or wobbling but it was not sliding smooth on the rail and the source of traction was inside the block. So I think that missing balls may be effecting since those are creating void in the circulation circuit. Any body who have the knowledge can share the size of the ball inside the MGN12 Block. So that I can fill it and see.
I don't have a digital calipers more over what if the provided balls are off specs. I just want to know the standard.
Pics attached.
