AMT Post Processing Solutions
AMT PostPro Capabilities
AMT are driven by the vision of transforming 3D printing from a prototype development tool into a reliable manufacturing technology suitable for high-volume production.
AMT PostPro is a groundbreaking digital technology platform designed to streamline and automate the traditionally cumbersome and expensive steps of 3D printing post-processing. AMT’s mission is to make automated finishing technology accessible for every 3D printer. Discover the 3D printed part cleaning, smoothing and sealing post processing solutions from AMT:
Part Unpacking
Unpacking is the first step of powder-based 3D printing post-processing where you free the part from the “powder cake” (the solid block of fused and unfused material) inside the build box.
The process is designed to safely and efficiently clear away large volumes of loose powder to physically uncover and extract the printed part from the container, before going onto the next stage of depowdering for precision cleaning.
Part Cleaning/Depowdering
Depowdering is the next step in post-processing powder-based printed parts, such as selective laser sintering (SLS) or multi-jet fusion (MJF).
It is a process in which residual powder is cleared from 3D printed parts using compressed air and blasting media, without damaging intricate details of a print.
Correct depowdering is essential for the part’s functionality and prepares it for any further post-processing steps, such as surface blasting or vapor smoothing.
Surface Blasting/Smoothing
Surface blasting is a technique used to smooth and polish the surface of 3D printed parts. This process involves blasting the surfaces of parts with a steady stream of blasting media to reduce surface roughness.
The blasting media gently abrade the surface, removing imperfections and creating a more uniform and aesthetically pleasing finish. The process can be combined with vapor smoothing for a sealed and even smoother finish.
Vapor Smoothing/Sealing
Vapor smoothing is a finishing process in which the rough surface of a printed object is exposed to vapors under controlled conditions.
The vapor condenses on the part’s surface, eliminating peaks and troughs, and enhancing the parts strength, aesthetics and water tightness.
AMT Post Processing Advantages
Safe and easy to use
The PostPro machines are a fully closed-loop system designed to ensure operator safety. The system includes a consumable recovery process, with AMT supporting the collection and delivery of recovered consumables, enabling safe and environmentally responsible operation.
Enhancing part properties
The original technology that cleans, smooths and seals the surface and internal cavities of 3D printed polymer parts, while also improving mechanical properties.
For production environments
PostPro machines are a step up in post processing technology and include advanced features to provide a state-of-the-art post processing experience. PostPro machines have been designed and built for production environments and high-volume throughput to enable industrial scale additive manufacturing.
Easy consumable handling
Proprietary safe pour cartridges and no-hassle, non-hazardous packaging for fast and efficient delivery.
Part Unpacking Automation Machines
Automated unpacking is the essential first step in a fully connected additive manufacturing workflow. At AMT, their PostPro Unpacking solutions are designed to make the transition from 3D printed build to clean, production-ready parts faster, safer, and more efficient.
Manual unpacking of powder-bed fusion builds is time-consuming and exposes operators to dust and repetitive strain. The PostPro Unpacking range eliminates these challenges with intelligent automation, integrating mechanical vibration, pressurised air, and smart powder-recovery technologies.
Fully Automated Powder Removal
Delivering safe, consistent, and highly efficient removal of excess powder from 3D printer build cakes through a fully automated unpacking process.
Closed Loop Powder Recovery
Direct integration with the AMT Powder Recovery System enables continuous powder reclamation, minimizing waste while maximizing material efficiency.
Dedicated Printer Compatibility
Designed with dedicated interfaces for HP NCU and EOS P3 build units to ensure precise, repeatable integration into industrial polymer workflows.
Digital Factory Connectivity
The PostPro Unpacking system acts as the "missing link" connecting printing, depowdering, and vapor smoothing into one fully automated production line.
Part Cleaning/Depowdering (DP) Automation Machines
Depowdering is a thorough process, involving compressed air and depowdering media (usually glass beads), to ensure all residual powder is cleared without damaging the intricate details of the print. Correct depowdering is essential for the part’s functionality and prepares it for any further post-processing steps, such as surface blasting or vapor smoothing.
All of the AMT depowdering machines are ATEX-certified meaning they’re suitable for locations with combustible dust and media:
100% FULLY AUTOMATED PROCESS
The depowering process typically takes 10 minutes.
Ionization Unit
Through ionization static changes are eliminated and even the most minute particles are removed.
Consistent Results
Machine design guarantees batch to batch consistency.
Configurable Parameters
Adhering to predefined recipes and parameters, the process guarantees precise cleaning.
Surface Blasting (SB)/Surfacing Automation Machines
Surface blasting is a technique used to smooth and polish the surface of 3D printed parts. This process involves blasting the surfaces of parts with a steady stream of blasting media to reduce surface roughness.
The blasting media gently abrade the surface, removing imperfections and creating a more uniform and aesthetically pleasing finish. The process can be combined with vapor smoothing for a sealed and even smoother finish:
Fully Automated Process
The blasting process takes ~ 15-30 minutes depending on the desired finish.
Ionization Unit
Features of the part become more visible after the blasting process.
Uniform Finish
The pressure and rotation of the parts guarantees uniformity of the surfaces.
Dye Uniformity
Surface blasting is a pre-dyeing step that improves the color consistency throughout the surface of the part.
Vapor Smoothing/Sealing Automation Machines
Vapor smoothing enhances the surface of 3D printed parts, transforming rough textures into a smooth finish comparable to injection-molded products.
The PostPro SF-Series machines set a new benchmark on the post-processing market. With the largest chamber, fastest processing time, and smallest footprint on the market, the SF systems are the industry standard:
