9 New 3D Printing Materials Offer Weather and Heat Resistance

<p><small>3Dynamic Systems says its Carbon Fibre 3D Printer Filament can be used on any conventional Fused Deposition Modeling (FDM) or fused filament 3D printer. It's made using 15%-22% high-modulus carbon fibers small enough to fit through the nozzle, but long enough to provide the needed extra rigidity and reinforcement. It provides  structural strength of 85MPa and excellent layer adhesion with virtually no warping. Compared to conventional 3D printing filaments, this makes it especially useful for applications in on-demand parts that require superior stiffness, ease of printing, and lighter weight parts. Examples of use cases include low- to no-volume parts, rapid moldmaking, and fixtures for custom processes, for items such as frames, supports, propellers, and working tools.

This batch of the latest 3D printing materials features materials that are resistant to electrostatic discharge (ESD), UV, and weather.

This batch of the latest 3D printing materials features materials that are resistant to electrostatic discharge (ESD), UV and weather, are composites, or contain graphene or carbon fiber for strength and durability. Most are black, but several come in other colors, too.

One of the new materials is a steel-filled filament, which is still relatively unusual, from colorFabb. Both colorFabb and Virtual Foundry are two companies that have made metal-filled 3D printing materials. Another material that's a beautiful silvery white is a heat-resistant PLA from Philament. Most of these are made for professional engineers and industrial products, although several are for desktop printers, and all but one are commercially available for purchase.
