Increased Production Yield and Quality
Monitoring and regulation of temperatures during every process stage of 3D Printing & Additive Manufacturing is critical to ensure high quality parts production. Optris provides a full family of infrared temperature sensors and three short-wavelength IR cameras optimized for temperature measurements on metal targets.
Short wave infrared cameras are becoming increasingly popular for temperature monitoring in additive manufacturing because they can easily monitor temperatures on the entire weld pool and track temperature data on the hottest spot eliminating the need to precisely target a single spot sensor. Optris IR cameras are now used in many additive manufacturing applications as an integral tool to increase both production yield and product quality.
Additive Manufacturing Applications
Laser Metal Deposition (LMD)
The Laser Metal Deposition is an additive production process that uses a laser beam to form a pool of molten metal on a metallic substrate. The metal powder is brought into that melt pool continuously via a nozzle. The sensor for temperature measurement must withstand the high energy density of the laser or its reflections.
Selective Laser Melting (SLM)
The Selective Laser Melting is an additive manufacturing technique developed to melt and fuse metallic powder via a high power density laser. The body of the designed 3D part is built by selective melting and re-solidifying metallic powders in each layer. The building platform is lowered by a tiny fraction and a new layer of powder is deposited.
Cladding / Wire Arc Additive Manufacturing (WAAM)
The Wire Arc Additive Manufacturing is a combination of two processes: Gas Metal Arc Welding and additive manufacturing. The metal wire is melted by using an electric arc and deposited layer by layer until a desired 3D shape is created. The heat of the former layer may influence the shape of the next layer. A temperature monitoring during the cladding process and the information of the heat distribution gives feedback of the quality of the welding process.
