CAM 3DP utilises an industrial grade 3D printer to additively manufacture your digital files, layer by layer, into strong end use parts. To be more specific the process used by our system is fused deposition modelling (FDM), which is capable of producing components in tough ABS engineering polymer.

By depositing the ABS in layers complex organic shapes or fully working assemblies, such as the spheres below, can be made into physical models in one go - this cannot be achieved using any other technology. Essentially the addition of undercuts and other complicated geometries are free, which is in contrast to many other industrial processes.

The reason why these design rules can be ignored is due to the system's use of secondary support material, which works alongside the ABS model material to keep the print from collapsing. Unlike other FDM systems, this type of material is soluble and is dissolved away using a detergent bath, preserving the excellent surface finish of the part which is not achieved by snapping the support off.

As the environment inside the printer is carefully maintained at a high temperature as to prevent parts from warping aiding in allowing accurate models to be produced in a repeatable way. The soluble support material also prevents undercuts from drooping to help maintain part accuracy.
