Powder bed fusion manufacturing redefines prototyping.

Powder Bed Fusion (PBF) is an AM process that uses either a laser or electron beam to melt and selectively fuse regions of a material powder. The PBF process encompasses several printing techniques: Direct Metal Laser Sintering (DMLS), Electron Beam Melting (EBM), Selective Heat Sintering (SHS), Selective Laser Melting (SLM) and Selective Laser Sintering (SLS). EBM methods require a vacuum but can be used with metals and alloys to create functional parts. All PBF processes involve the spreading of the powder material over previous layers. The powder is sintered layer by layer. After each layer of the part is created, a platform lowers the model.

Employing PBF technology in unique ways, CalRAM translates your ideas into reality more quickly, and accurately than any other prototyping method. CalRAM’s direct-from-CAD 3D printing capabilities reduce or eliminate tooling, resulting in shorter R&D design cycles and more efficient design iterations. The layer-by-layer AM technique makes internal design structures and cooling capacities possible in a way that subtractive manufacturing simply can’t. Plus, concept evaluation and design adjustments can be addressed in the early stages of development. What’s more, functional prototypes — made from the same materials as the final component — enable the testing of design, tolerance and material properties under real world conditions.
