AMT PostPro3D

AMT PostPro3D

The only automated turnkey 3D post-processing technology delivering end-use parts at scale.

AMT Post Processing

AMT’s PostPro3D technology is a smart and automated post processing solution for smoothing thermoplastic polymer 3D printed parts. PostPro3D achieves a high quality surface finish that matches injection molding techniques using 3D printing processes. This enabling technology, offered by Fathom Digital Manufacturing reduces lead-time, cost of manufacture, operational and maintenance costs providing the ‘missing piece’ in the digital manufacturing chain.

The PostPro3D machine makes 3D part surface finishing speed and cost competitive for high volume production. Talk to an expert at Fathom today to take your parts to the next level using AMT PostPro3D for post processing.

“The AMT PostPro3D finishing worked great for my application—smoothed the surface so the mating parts slid nicely together. Thanks for suggesting it.” – Mike, Principal Engineer, Global Telecom Supply Company

Selective Laser Sintering (SLS), Fused Deposition Modeling (FDM) and Multi Jet Fusion (MJF) have become popular among designers and engineers for many reasons. All of these 3D printing technologies allow for higher productivity, lower cost per part and for design flexibility. With the addition of AMT PostPro3D finishing, achieve surface quality similar to injection molded parts without the costs of tooling or longer lead times.

Selective Laser Sintering (SLS) is a commonly used powder-based additive technology to create models, prototypes and end-use parts in durable, engineering-grade thermoplastics. Consider SLS technology for applications that involve high-complexity and organic geometries, as well as parts requiring durability. SLS nests in the z direction which allows for short-run production and efficient builds. This technology is also capable of producing parts with finer details than most other processes that use high-strength plastics, however, surface finishing is recommended.

Fused Deposition Modeling (FDM) is ideal for building concept models, functional prototypes and end-use parts using standard, engineering-grade and high-performance thermoplastics. FDM is a filament-based additive technology distributed by a moving print head that extrudes a heated thermoplastic material in a pattern layer-by-layer onto a build platform. FDM is the best choice for jigs and fixtures, molds, tooling and other functional parts that require durability and resistance.

Multi Jet Fusion (MJF) is ideal for enclosures, electronics housings, complex ducts, lattice structures and functional assemblies. MJF is capable of 3D printing parts with high detail, as well as suitable for applications that require durability. MJF builds parts by laying down a thin layer of powder on a print bed over and over. The inkjet array in the print carriage sweeps over the print bed, jetting two agents downward—a fusing agent and a detailing agent.
