Whether 3d printing is safe or not?

Is 3D Printing safe? Of course the question does not have an easy yes/no answer. In this article we’ll look at several sides of the safety of 3D printing including the safety of the hardware, the materials used and the 3D printed objects.

Are 3d printers safe?

It is due to that 3D printing has become a mainstream technology used across many industries rather than a niche technique for prototypes and highly personalised consumer goods, the safety of 3D printers also has become a topic of discussion.

What makes 3d printer safe?

When you study that whether 3d printers safe or not, you should keep something in mind:

• Electrical safety
• Mechanical safety
• Risk of burns

Electrical safety

When buying 3d printer, please check if the supply meets all CE mark regulations and is protected against short-circuit, overload, over voltage and over temperature.  A nice feature could be that the hotend of the printer contains thermal runaway protection. If the temperature is too high, monitor the temperature by installing a hot melt fuse on the heatsink and remove all power from the heater.

Mechanical safety

Big 3d printer containers many moving-parts. Luckily, industry-wide most used NEMA-17 stepper motors do not have enough power to cause serious injuries. Therefore, you may want to limit your search to 3D printers that have a “closed” design.

Risk of burns

Since most 3D printers’ extruder  can reach temperatures up to 280 ° C and heated beds up to 120 ° C, there is a potential risk of burns.

Safety 3d printing materials

So, now that you’ve bought a seemingly safe  huge 3D printer, but the actual printing starts, leading to a variety of new risks. And what 3d printing material can print safely?

ABS was once the most popular 3D printing material.  Engineers love it for its strength and designers like it cause it’s easily polishable with acetone.

Any other better choice? Of course you can use PLA, PLA is a bioplastic, considered as the safest 3D printing material.

Above are some points of safely 3d printing, I want to tell you that our auto bed leveling 3d printers are safe and the filament we present is also safely! Please be rest assured to buy!
