Just 3D Printed A Chess Set

This one below is more expensive but it has both white and grey filament and it even says "food safe" on the package.

And it can be shipped to my location, for some reason the other brand only lets me ship the yellow one.

Look closely what was tested.

The PLA and PETG were tested as food safe. No where does it say that any of the dyes were tested. Plus, the fact remains that the tiny wavy lines on 3D printed parts give crevices which are perfect breeding grounds for bacteria.

I got the filament and it even says food safe on the cover.

Amazon said it was going to be delivered on Wednesday, so I was in the middle of printing all the shapes in my white filament, I think I'll do that before I make the food safe shapes.

I'm utterly scandalized at the implication that a company selling things on Amazon could potentially be deceitful about the properties of an item for sale! They have a reputation to uphold, you know

That, and all the warnings here:

Food-grade 3D printing: Is PLA Food-Safe?

Here's what you need to know in order to 3D print safe food containers, utensils, and kitchenware using PLA filament.

www.wevolver.com

Basically natural PLA by itself is usually food safe, but
(1) most colorants are not food safe,
(2) many of the 3D printing nozzles are not food safe, even if you could find a food safe filament,
(3) many times there will be traces of what you previously printed in the equipment meaning you might use food-safe filament in a food safe nozzle but carryover from a previous print makes it not food safe,
(4) and even if you have all of the above covered, once it is 3D printed the grooves are perfect breeding grounds to make it not food safe after it has been handled. This is especially true since PLA cannot be heated very hot to sterilize it while washing.

Then that website goes on to mention some epoxies to help with many of those issues. Fill in the grooves to reduce bacterial growth and to block most of the hazards from leaching out. Just be sure that the coating remains intact (unlikely with a toddler).

AFAIC, for human contact/consumption, plastic starts at 'not great' and ends at 'fucking terrible'. I use plastic, cause that's the way it is, and it's hard to avoid, but I wouldn't build anything for human use out of it myself.

Don't hate the PLA-er, hate the game.

Apparently "chrome yellow" is sometimes used in those yellow PLAs, and it is toxic. I'm having a hard time finding proper SDSes for these filaments, which isn't all that surprising, I guess.

Just got this at the downtown library, I'm trying to learn how to make shapes with less pointy edges.

Always good to see people using their local library.

Ok, with tinkercad i figured out how to smooth the edges for the cube and cone, but not the pyramid.

For some reason the pyramid doesn't let me adjust the "radius" for the shape.

It's called a "file". They can add or remove sharp edges.
