Polyplastics of Japan has developed a 3D printing technology for the production of Duracon polyoxymethylene (POM) resin. The technology, known as material extrusion (MEX), is reported to provide 3D printed parts with physical properties approaching those of injection molded parts. Polyplastics will showcase new 3D printing technologies at K 2022 in Düsseldorf, Germany from October 19th to 26th. The company will be present at booth B02 in Hall 7A.
Generally, only amorphous or low crystallinity resins such as ABS and polyamides are compatible with the MEX 3D printing process. The high crystallinity and high crystallization rate of POM make it unsuitable. To address the limitations of POM, Polyplastics’ MEX 3D printing technology combines the selection of a more suitable grade of POM with printing conditions optimized for its crystallization.
The MEX process can be used to pre-evaluate physical properties, function, durability, and other properties without the use of tools, helping to accelerate product development. It can also be used for small-scale production of non-standard products. Using filaments as input material, the MEX method creates three-dimensional structures by repeatedly tracking and layering deposition of molten material extruded through tiny nozzles.
Polyplastic company patents Duracon POM 3D printing technology. In the meantime, the company is developing other Duracon POM filament materials for 3D printing, including reinforced grades.
