That was almost alarmingly to-the-point, well done!

This is a great vid, I search this topic like once a year and this is the first time I’ve actually found what I’m looking for. Thank you!

Thank you! It was a struggle to figure this out, so I'm glad it's helpful!

Wow, so much good information and not in some lengthy video with a bunch of self promotion. Thanks Alex!

Didn't know this was possible! Can't wait to print dog food bowls or maybe dog toys.

Thankyou!!! You are the only video on the internet I’ve found with a solution. 🙏🙏

I came across this video because of your battlebot video. Very informative and interesting. If I ever want to print a bowl or something for food I have to thank you!

I'm really a fan of 3D printing with anything and coating it. But I'll consider a stainless steel nozzle

Great info!!

hit every point perfectly

I am planning to try this with TPE FROM FILAMENTUM

Great video not to long and gets the information across.

I really appreciate this video - I've been trying to figure out a way to print food-safe parts for years for use on old pharma/nutraceutical equipment. I just got some Filamentum HIPS and have been experimenting a bit with it and Limonene. I just did my very first test spray with a an aerisolizing spray bottle. Defintely see that they layer lines have smoothed out, but the surface is not terribly smooth as I was handling the print and trying to wash it. Can you explain in a bit further detail your process for spraying limonene on the prints? Do you spray, allow to sit for some time and then wash? Spray and leave it? How long to dry? Any recommendations for achieving the best surface finish?

I usually sand my parts before spraying on the limonene, and/or I put them into a vapor bath for 30 minutes or more.

Although if you can dissolve it with lemon juice is it really food safe? 🙈

Alot of good information i think ill give it a spray aswell Do you have any recommendations on a truly food safe permenant coating paint, silicone?

I can't remember any specific silicone sprays because I like my own method so much better, haha.

r you try other products(when those 2 r not available)what is replacement for them

Isn't vapor smoothed abs food save as well?

Some ABS plastics are food safe, but not all of them, either because of their chemical makeup, or because it's extruded into filament on machines that are not food safe. I wasn't able to find any ABS supplier whose filament was known to be food safe.

Does the plastic survive being used with lemonade or orange juice, without leeching into the the juice?

good question lol

goated

Its just extra flavour

Great! But the nozzle is not the only variable in the printer. Your whole filament path needs to also be clean, including extruder gears, PTFE tube and heatbreak.

The nozzle is the area of most concern I think, but you're right. I got a stainless steel heatbreak as well, PTFE is already food safe, and the drive gears... well, they're nickel-plated, which is safe for cookware, but probably not so much if the coating ever flakes off from corrosion, so I figured my drive gears are fine.
