Frequently Asked Questions

What Materials Cannot Be 3D Printed?

You'll find that certain materials, like metal alloys, radioactive materials, biological tissues, explosive compounds, toxic chemicals, high-temperature ceramics, fiber optics, liquid crystals, rare earth magnets, and delicate fabrics, are still off-limits to 3D printing due to technical limitations.

Does Silicone Stick to 3D Printed Parts?

You'll find that silicone adheres well to 3D printed parts, thanks to its tacky nature, but you can improve bonding by optimizing printing surfaces, part geometry, and surface treatments to achieve strong bonds and reliable material interactions.

Does PLA React With Silicone?

You'll be relieved to know that PLA, composed of renewable resources, doesn't react with silicone due to its chemical properties, forming no strong chemical bonds, and its low printing temperatures prevent thermal degradation, ensuring a clean release.

Is There Anything Illegal to 3D Print?

When 3D printing, you must avoid copyright infringement, patent violations, and illegal designs, like firearm restrictions, counterfeit products, and banned objects, as these can lead to serious legal consequences and unethical printing of forbidden artifacts.
