Novel multi jet fusion 3D-printed patient immobilization for radiation therapy. [PDF]
J Appl Clin Med Phys, 2022 AbstractPurposeThermoplastic immobilizers are used routinely in radiation therapy to achieve positioning accuracy. These devices are variable in quality as they are dependent on the skill of the human fabricator. We examine the potential multi jet fusion (MJF) 3D printing for the production immobilizers with a focus on the surface dosimetry of several ...

Study on Geometry, Dimensional Accuracy and Structure of Parts Produced by Multi Jet Fusion. [PDF]
Materials (Basel), 2021 Multi Jet Fusion (MJF) is one of the newest additive manufacturing technologies for polymer powders, introduced in recent years. This fully industrial technology is gaining big interest as it allows fast, layer-by-layer, printing process, short production cycle, and very high printing resolution. In this paper, twelve thin-walled, spherical PA12 prints

Accuracy and Powder Removal Limits in Multi Jet Fusion 3D Printing. [PDF]
Polymers (Basel)Multi Jet Fusion (MJF) is a leading technology for producing functional polymer parts. However, it still faces challenges with dimensional accuracy and removing unfused powder from complex internal geometries. First, dimensional accuracy was mapped by producing 45 identical PA12 specimens on an HP MJF 4200 printer in a 5 × 9 layout across five vertical
