3D printed toys are popular for good reason: they're customisable, often more creative than mass-produced toys, and can be made in just about any shape. But "3D printed" is a manufacturing process, not a safety standard. It says nothing about the quality of the material or the quality of the making.
Are 3D printed toys safe for kids? It relies on three things: the material, the quality of the print, and whether the design is age-appropriate.
What's the Material of the Toy?
Before choosing a 3D printed toy its worth knowing what it's made of. The material determines how safe it is to handle, chew on, or hand the toy to a young child. Let’s take a look at commonly used materials:
PLA
PLA is the most commonly used 3D printing material for toys. It's made from plant starches such as corn or sugarcane rather than petroleum, and that is why it is widely seen as a safer, more environmentally friendly alternative to regular plastics.
That said, a PLA toy doesn't automatically mean the toy is safe just because it's plant-based. A few points parents should keep in mind:
- Its not meant for extended chewing. PLA shouldn't go in a child's mouth for extended periods, even though it's non-toxic.
- Watch the additives. Bright colors, glitter, or glow-in-the-dark effects come from additives, and those aren't always tested the same way the base plastic is.
- Cheap prints can snap into sharp bits. A poorly printed PLA toy can break into small, jagged pieces rather than dulling down like a molded plastic toy would.
- The surface holds onto grime. 3D printing leaves faint ridges layer by layer, and those tiny grooves can trap dirt and bacteria over time if the toy isn't wiped down.
PLA is a good starting point, especially compared to older, petroleum-heavy plastics. But the quality of the print matters just as much as the material.
PETG
PETG is a modified version of PET plastic, the same type used in most water bottles, with glycol added to make it easier to print and more resistant to stress. The biggest advantage over PLA is flexibility: rather than cracking under pressure, PETG will bend a little and absorb the impact.
In general, PETG is safe for kids' toys. Some reasons why it works well for kids to use:
- It handles drops and impacts better than PLA. It bends rather than breaks, so there is less risk of sharp broken edges.
- Already a staple in everyday products. PETG is a common, well-established plastic, not some exotic, untested material.
- More tolerant of roughhousing. It's a good choice for toys that get thrown, sat on, or handled roughly.
For rougher children and their toys, PETG is often the more durable of the two.
ABS
ABS has been used in toys for ages before 3D printing came along — Lego bricks are made of it, for example. It's a tough, heat-resistant plastic, which explains its long track record in the toy industry:
- Very durable. It resists cracking and impact well, even under regular rough handling.
- Handles heat better than PLA or PETG, which matters for toys left in direct sun or a hot car.
- Long-standing history of use in traditional, non-printed toys.
- Better suited to toys that won't be mouthed frequently. Some research has examined whether trace amounts of chemicals, such as styrene, can release from ABS over time. This is more relevant to toys that are chewed on constantly than to toys that are simply handled during play.
For an older child who isn't putting toys in their mouth, a well-made ABS toy is a durable, dependable choice.
Beyond the Material: Other Safety Factors
Even a non-toxic plastic can end up in an unsafe toy if the design, size, or finish is off. The material is only part of the story.
- Design. The toy shall have no sharp points, thin sections, or easily breakable parts. Any moving parts will need special attention, as they can create pinch points or become loose with use.
- Size and choking hazards. Small parts are one of the biggest concerns for young children's toys. A 3D-printed toy may look large overall but still have small pieces that come loose — wheels, accessories, joints, and similar movable parts are common culprits. If a child still mouths objects, avoid toys with small detachable components.
- Age appropriateness. Not every 3D-printed toy suits every age. A detailed model with small parts may be fine for an older child but risky for a toddler. When judging whether a toy is safe for babies specifically, the bar is higher: larger, simpler designs with no easily removable parts.
- Surface and finish. The finished surface should be checked before a toy is handed to a child. Rough areas, sharp edges, cracks, or protruding pieces can cause minor injuries and tend to worsen with use. Running a hand over the toy, especially around corners and joints, is a quick way to catch problems. If it has visible cracks or loose sections, it should be set aside until repaired or replaced.
Nexbie's Approach to Safe 3D-Printed Toys
Much of what makes a 3D-printed toy risky comes down to how it was printed, not just what it was printed with. A rushed print can leave weak seams, rough surfaces, or thin walls that crack under normal play, even when the filament itself is safe. This is why buying from an established brand rather than an anonymous small-batch listing makes a real difference.
Nexbie's 3D-printed toys are built with this standard in mind:
- Made from PLA, a safe, eco-friendly material appropriate for children's toys.
- Finished properly, with edges sanded and rounded rather than left sharp or rough straight off the printer.
- Printed to a consistent build quality, with wall thickness suited to regular handling rather than display-only detail.
The lineup includes articulated animals and dragons, action figures, and a range of other designs, giving parents room to choose based on a child's interests and age rather than settling for whatever is available.
Frequently Asked Questions
Q: Is PETG safe for kids' toys?
A: Yes. PETG is a common, tested plastic that is more resilient to drops and rough play than PLA because it bends rather than cracks.
Q: How durable are 3D printed toys?
A: It all depends on the material and how it was printed. PETG and ABS are more impact resistant, while PLA is more prone to cracking if the toy is dropped or thrown around a lot.
Q: Are 3D printed toys toxic?
A: No. Common filaments like PLA and PETG have low baseline toxicity, and neither releases harmful substances. The bigger concerns aren't about toxicity in the traditional sense; they're about sharp edges or weak points from poor printing.
Q: What are 3D printed toys usually made of?
A: Most are PLA, PETG, or ABS. PLA is the most common because it's easy to print with, while PETG and ABS are picked when extra toughness matters more.
Conclusion
3D printing doesn't make a toy safer or riskier on its own — it's just a manufacturing method. What actually matters is the plastic used, how cleanly it was printed, and whether the design fits your child's age. PLA, PETG, and ABS can all work well in the right toy; the difference comes down to finish quality and detail size.
Before giving a printed toy to a child, it's worth a quick check: run a hand over it for rough spots, look for any small pieces that could come loose, and confirm the design suits their age. Choosing a brand that takes both material and finish seriously, and checking toys periodically for wear, goes a long way toward making play safer.
