With every new generation of machines, additive manufacturing is getting more precise, cheaper and faster. However, tolerance comparable to CNC technologies cannot be achieved yet. In this article, we introduce you to tolerances in 3D printing: what are realistic accuracies and what are the most important factors.
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.
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.
