About Polycarbonate 3D Printing

Polycarbonate (PC) is a kind of engineering plastic with high strength, high impact resistance and excellent high temperature resistance, and its insulation performance is good, which can be used as electronic and electrical parts. Its glass transition temperature is up to 150°C or more, and the printing difficulty is higher than that of PLA and ABS, requiring higher printing temperatures. Some grades of PC can withstand high temperature autoclave and are ideal for medical and food applications. PC can be rapidly formed by 3D printing for functional prototyping and small volume production in automotive, medical and other industries.

FDM PC

Standard polycarbonate material mechanical strength is outstanding, including tensile strength, impact strength and bending strength are better than other engineering plastics such as ABS, but also has high hardness and thermal stability. This makes standard PCS ideal for functional prototyping and tooling, as well as structural end-use parts that require high rigidity and impact resistance, replacing metal for a wide range of high-strength components.

FDM PC-ABS

PC-ABS is a transitional engineering plastic that combines the high strength and high temperature resistance of polycarbonate with the toughness and processability of ABS. It inherits the common advantages of the two materials, with a certain strength, toughness, processability and high temperature resistance, and can be produced through 3D printing technology that requires both a certain strength and a certain toughness and processability of various types of engineering parts and product prototypes, with a wide range of applications.

FDM PC-ISO

This special grade of polycarbonate material is both biocompatible and repeatable, non-toxic and harmless, and meets ISO 10993 and USP IV standards. It inherits the excellent mechanical strength and high temperature resistance of polycarbonate itself, and can be autoclaved with gamma rays or ETO gas without residual contamination. Therefore, this PC material is an ideal 3D printing material choice for the medical and food industries.

Finishes

When using FDM technology to print polycarbonate, the post processing mainly by removing the support structure, grinding treatment to achieve the basic effect. Its surface will have an obvious layered texture, which cannot achieve a high degree of smoothness. With three color options of black, white and transparent, richer color personalization is not possible. If you want a highly smooth look, consider using technologies such as SLS or MJF. It can also be painted and sprayed to achieve personalized customization of the appearance. The polycarbonate material itself can be finely matted, which can significantly improve the surface texture and achieve a better smoothness.

Cost-saving Design Tips

When printing polycarbonate using FDM technology, you need to pay attention to the following design strategies:

  1. The printing direction makes the overhanging part need to be supported, and large inner cavity structure should be avoided. Soluble support materials can be used for removal.
  2. In order to exert the mechanical properties of the material, avoid designing the structure that bears the load in the vertical printing direction.
  3. PC is relatively expensive and is recommended only when high strength and high heat resistance conditions are required.
  4. Evaluate the need for a PC based on the actual load conditions and operating environment.
