Fluid Tightness of HP Multi Jet Fusion PA 12 Components

Beitragsbild Wasserdichtheit von HP Jet Fusion PA12 Teilen

Fluid tightness is an often-discussed topic in 3D printing. While industrially manufactured laser sintering parts are rather porous and therefore often not water tight, HP’s multi jet fusion technology generates parts that are fluid tight without further processing. This article provides an overview of the part characteristics, incl. wall thickness and geometry recommendations.

HP Jet Fusion vs. Laser Sintering

When HP announced the key features of their new 3D printer ‘Multi Jet Fusion 4200’ in 2014, they promised it would introduce a new kind of additive technology, which would print parts that were more accurate and stronger than those produced by FDM and laser sintering printers – and at ten times the speed. Now that the HP Multi Jet Fusion 4200 has been on the market for a few months, it is time to take an in-depth look at the most important characteristics of both technologies and most importantly, at the quality of the 3D printed parts that they are capable of producing.

Rapid Prototyping: Process and Applications

Many researchers say that the technology of Rapid Prototyping (RP) is going to get more and more important fort the future. So we want to give you some information about it. The term rapid prototyping established itself as topic for many 3D printing applications. But other manufacturing methods which rely on CNC-controlled (computerized numerical control) ... Read More

How to create molecule models for 3D printing

how-to-prepare-moleculemodels-for-3d-printing
Over the last few decades, we have been able to significantly improve our understanding of the three-dimensional structure of large molecules, like nucleic acids and proteins, and how this relates to their function. With resources like the Protein Data Bank or the Nucleic Acid Database, in combination with modifiers such as Pymol, Chimera, JSmol and ... Read More
