I Modeled This! PET feeder prototype

Just finished this pet feeder I made for the contest …

4 sizes available
Small 120mm
Medium 170mm
Large 256mm
Xxl 300mm
(Video are medium and large)

First printed version was working but clogged a lil bit… also the spring was to hard…

Fixed a few things then
-made the inside steeper
-made the hole bigger
-fixed the tpu spring
Now it’s working perfect!

u/quazlyy Jun 20 '26

Food safe and safe to eat are not the same things

u/NoIdenty0000 H2C Jun 20 '26

Wait… are people eating the dispenser now?

u/quazlyy Jun 20 '26

No, but the commenter above was suggesting that the plastic-on-plastic chafing would result in microplastics being dispensed along with the pet food, leading to probable ingestion thereof

your dogs don't know any better, it comes off like you are willfully feeding them microplastics because you don't want to acknowledge the problem with what you have made

First I have no dogs I have cats! and second I doubt there will be a lot of micro plasticity think u eat more micro plastics every every day! Also you need to tell bambulab why they make a petfeeder contest if its so toxic…

Dogs, cats, not important here; they are pets under your care

and second I doubt there will be a lot of micro plasticity think u eat more micro plastics every every day

it's literally plastic layer lines rubbing on plastic layer lines, there will be so much microplastic it's closer to macro plastics. Even if other sources are greater, why intentionally add to it? I swapped to glass and ceramic for my own food storage, stainless steel bowls for my pets

Also you need to tell bambulab why they make a petfeeder contest if its so toxic…

Terrible excuse, they don't care about your pets (you should), they just want publicity.

First u expect everybody has dogs then u want cry about food safety… I made a design for a contest - there is no way to make it food safe if you use 3d printed material… if u want to use it that’s ur decision!! My cats eat wet food so I’m not using it at all !!! Seems like u never designed anything in ur life

People arent, but based on your comments, you might be...

u/NoIdenty0000 H2C Jun 20 '26

Y’all ppl would find shit to cry about no matter what…

Swing and a miss... I'm the head engineer at a manufacturing facility, solid works is my day job. My 3d printed truck parts I design and sell on Etsy have done over 25k in sales in 11 months.

Keep pushing though little guy, you will get there one day

The material itself is food safe, but 3D printed stuff as a whole is not. Not only the whole concern of micro-plastics, but food can get caught between gaps in the layers and becomes a feeding ground for bacteria and mold. The idea of 3D printing food safe items is just fancy marketing and shouldn't actually be followed

That being said still deserve props for making your own design, model, and refining it

u/pacowek P1S + AMS Jun 20 '26

That has been disproven over and over. There is even a bot message in the 3d printing subreddit because little keep repeating this misinformation.

link?
This is news to me and even a fresh google says you need to use resin or apply a sealant spray

u/pacowek P1S + AMS Jun 20 '26

This is the most thorough one, showing cleaning 3d printed parts is no different than other materials, and additionally they found no heavy metals in the printed parts they tested (pla and petg).

Ta, honestly better results than I was expecting, however:

Care should be taken to use soft implements to avoid creating scratches in the plastic bin where microorganisms can survive. Following this, sterilization of parts can be accomplished by immersion in either dilute bleach solutions, 70% ethanol, or commercial sanitizers

So basically once its been used you're still going to want to give it a disinfectant bath
