Exactly the video I was looking for! Thank you!! For anyone wondering, shipping from Fillamentum to the U.S. is (unfortunately) steep: $41 for two spools of HIPS filament. Hopefully a company in the U.S. jumps in on this!
Thank you -- quite informative and almost everything I needed to know. Just one question -- it may seem a stupid one -- does the limonene treatment also help make the prints water tight? My I'm looking at getting into 3D printing to make printable parts that can be used for growing microgreens and some produce at home -- also some vertical bins for vermiculture -- so not only does it have to be food safe (leeching harmful chemicals and heavy metals into the food would of course be no bueno) but also needs to be able to hold the water that is meant for the plants. If it doesn't hold water, it's just a mess waiting to happen.
Hi Alex’s thanks for the video I’m trying to do hydroponic growing tower do you think this 3 step process will work for my materials water will go through them and thanks for the video it is really great video
Oh well that should be easy! All you need to do is seal your parts, which can be done with vapor smoothing (ABS or ASA with acetone, HIPS with acetone or limonene, or even Polysmooth with alcohol), or just by spraying on silicone or any other waterproof coating.
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 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 was wondering about 3d printing acrylic parts for use in food safe products. Is 3d printing acrylic even a thijg and could it he used for food safe products 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.
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.

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!
That was almost alarmingly to-the-point, well done!
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.
Thank you, you knocked it out of the park👊
Thankyou!!! You are the only video on the internet I’ve found with a solution. 🙏🙏

I think it should. Just like acetone vapor smoothing, using limonene on HIPS should melt the surface just enough to close small pores.

Thanks for the explanation great video I subscribed to your channel 🫡

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

Thanks my Guy for the vid, simple, effective !
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.
I am planning to try this with TPE FROM FILAMENTUM
hit every point perfectly
Great info!!
r you try other products(when those 2 r not available)what is replacement for them
Great video, to the point :) Thanks!
HIPS printed parts are only stable up tp 85°C, so no hot food, not hot drinks, no dishwasher ... which makes it rather impractible 😢
Great video not to long and gets the information across.
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
I'm really a fan of 3D printing with anything and coating it. But I'll consider a stainless steel nozzle
Please do. The brass ones contain lead!

@@alexsalchemyis this still the case? Any ABS updates?
Although if you can dissolve it with lemon juice is it really food safe? 🙈
nice
Its just extra flavour
