Multi Jet Fusion is a powder-based technology but does not use lasers. This chapter summarizes the recent research in the laser-based powder bed fusion process. Release status: Just started Description: Building a Powder bed 3D printer. Anglais [modifier le wikicode] Cette entrée est considérée comme une ébauche à compléter en anglais. Procédé de fabrication additive dans lequel l’objet est obtenu par la fusion sélective de certaines zones d’un lit de poudre. 2.1.A laser beam scans at a controlled speed the selected locations of the powder bed and fuses the powder to the solid material underneath by either full melting [selective laser melting (SLM)] or … Définition, traduction, prononciation, anagramme et synonyme sur le dictionnaire libre Wiktionnaire. Röntgen-Ångström is a German-Swedish research collaboration in structural biology and materials science.
A hybrid system that combines powder bed fusion with CNC milling is offered by the Japanese company Matsuura. The project aims to employ high-speed synchrotron X-ray imaging to monitor the Electron Beam Powder Bed Fusion (E-PBF) process in situ and in real time.
The term "3D printing" can refer to a variety of processes in which material is joined or solidified under computer control to create a three-dimensional object, with material being added together (such as liquid molecules or powder grains being fused together), typically layer by layer.
While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly. Powder Bed Fusion (PBF) 3D printing technology spawns products with precision. The powder bed is heated uniformly at the outset. Laser Powder Bed Fusion is an additive manufacturing process in which thermal energy (from a laser) selectively fuses regions of a powder bed layer by layer. Powder bed fusion (PBF) methods use either a laser or electron beam to melt and fuse material powder together. These originated from work at the University of Texas at Austin in the early 1980s which was awarded a patent in 1989,. All PBF processes involve the spreading of the powder material over previous layers. Contributors: Based-on: Categories: Powder. Powder Bed Fusion.

In this way the 3d file can be printed. The end part(s) can be extremely complex and contain features not possible with conventional subtractive manufacturing processes. License: GPL. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution.
