Is a 3D-Printed Dog Bowl Safe? An Honest Guide to Ours
The short answer
Our dog bowls are fully 3D printed in PETG, a tough plastic from the same family as drinks bottles, with the name printed in as part of the bowl. Printed plastic has fine layer lines, so we don't call it food safe or dishwasher safe. Hand wash it after use, keep it out of the dishwasher and replace it if it gets scratched or chewed.

People ask us this more than almost anything else: "Is a printed dog bowl OK to use?" Our personalised dog bowl is printed in one piece, bowl and name together. Here's an honest account of what that means, so you can decide whether it's right for your dog.
The short answer
A printed bowl is a solid, tough plastic bowl, and lots of owners use one happily. It isn't the same as a glazed ceramic or a moulded bowl, though. Every 3D print has very fine lines where the layers meet, and those lines are harder to get perfectly clean than a smooth surface. So we don't call our bowls food safe or dishwasher safe, and we ask you to look after them in a particular way (below).
What it's made of
| Part | Material | Notes |
|---|---|---|
| The bowl | PETG, 3D printed | Tough and slightly flexible, copes better with water and knocks than PLA |
| The name | PETG in a second colour | Printed in as part of the bowl, not painted or stuck on, so it can't peel off |
PETG is a glycol-modified version of PET, the plastic used for most drinks bottles. We use it rather than PLA (the other common printing plastic) because PLA softens at around 50 °C and is more brittle. There's no paint, coating or metal anywhere on the bowl.
What we can't promise, and why
You'll see filaments sold as "food safe" or "food contact compliant". That label usually describes the raw plastic, tested before it's printed. It doesn't cover:
- the colourings in that particular spool,
- what happens when it's melted and pushed through a printer nozzle,
- the layer lines in the finished object, or
- how it's cleaned and used afterwards.
Prusa Research, a well-known printer maker, points out that layer lines can collect food and let bacteria grow, and it advises against using prints as food containers. One Australian print farm puts it this way: "Almost no filament maker tests the final extruded product for food safety."
We think those are fair points, which is why we don't make food-safety claims for any printed item. They're also why the care steps below matter.
How to look after a printed dog bowl
- Hand wash after each use in warm, soapy water with a soft brush or cloth, then rinse and let it dry.
- No dishwasher, no boiling water. The heat and strong detergents can warp the bowl or roughen the surface.
- Avoid scourers. Scratches make the surface harder to clean.
- Wet food: wash the bowl straight after the meal, as wet food leaves more residue than water or dry food.
- Water: change it at least once a day and wash the bowl when you do.
- Check it regularly. Replace the bowl if it gets scratched, chewed, cracked or starts to feel rough, just as you'd replace a worn plastic chopping board.
- Chewers: the bowl isn't a chew toy. Supervise heavy chewers, and take the bowl away if your dog starts chewing it.
Is it right for your dog?
That's your call, and we'd rather you made it knowing the facts. A printed bowl suits owners who want something personal and colourful and are happy to hand wash it and replace it when it's worn. If you'd rather have a bowl you can put in the dishwasher or sterilise, a plain ceramic or metal bowl is the better choice, and you could pair it with one of our silent dog tags instead.
Our bowls come in three sizes: small (0.45 litres, about 16 cm across) for toy breeds, medium (0.9 litres, about 20 cm) for most dogs and large (1.8 litres, about 24 cm) for big dogs. There's a double version, in small or medium, with food and water side by side in one piece.
FAQ
Is the bowl food safe?
We don't describe any printed item as food safe. Some PETG is approved for food contact before it's printed, but that doesn't cover a finished print with layer lines. Follow the care steps above and replace the bowl when it's worn.
Is it dishwasher safe?
No. Hand wash it in warm, soapy water. Dishwasher heat can warp printed plastic.
Can I use it for water?
Yes, many owners do. Change the water at least daily and wash the bowl when you do.
Will the name wear off?
No. It's printed in a second colour as part of the bowl, so there's nothing to peel or rub off.
How long will it last?
It depends on your dog and how it's used. Check it regularly and replace it when it's scratched, chewed or cracked.
What if something's wrong when it arrives?
Message the team with your order number and a photo. If it's faulty, we'll remake it or refund you. See returns.
