Unionfab 3D printing services leverage an Intelligent Manufacturing network of over 1,000 machines. We have an unmatched capacity to deliver parts within hours. In addition to a broad range of material selection, we offer several post-processing options to improve cosmetics or enhance mechanical properties.
We use the latest additive manufacturing technology to build affordable, functional parts in over 30 metals and plastics. Unionfab offers six high-quality printing processes, including Selective Laser Sintering, Fused Deposition Modeling, Stereolithography, Selective Laser Melting, Poly jet and Multi Jet Fusion.
IStereolithography (SLA) is a powerful 3D printing technique ever developed. It produces highly accurate and high-resolution, detailed parts. It’s used directly in end-use, low-volume production, or for prototyping. Unionfab offers over 30 uniquely engineered SLA materials to enable products to the market at reduced production costs.
Fused Deposition Modeling (FDM)
There are several different methods of 3D Printing, but the most widely used is a process known as Fused Deposition Modeling (FDM). FDM printers use a thermoplastic filament heated to its melting point and then extruded, layer by layer, to create a three-dimensional object.
Multi Jet Fusion is an industrial 3D printing process that produces functional nylon prototypes and end-use production parts as fast as 24 hours. The printers are unique in that they separate recoating and printing/fusing during the printing stage, making it possible for each process to be separately optimized for performance.
SLM is one of the most exciting 3D printing technologies available today and is utilized both for rapid prototyping and mass production. The range of metal alloys available is fairly extensive. The end result has properties equivalent to those manufactured via traditional manufacturing processes.
Selective Laser Sintering (SLS)
Selective laser sintering (SLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
PolyJet uses a jetting process where small droplets of liquid photopolymer are sprayed from multiple jets onto a build platform and cured in layers that form elastomeric parts.
