ABSTRACT
There are many, frequent announcements of technology developments for additive manufacturing done by universities as well as companies. These developments have to do with hardware, software and materials. They improve, in particular, the quality and speed of additive manufacturing processes but, by doing so, also affect the costs. For example, being able to produce more parts in a given time means that the machine cost per part goes down. Some developments are conceptually very broad in nature; for example, volumetric 3D printing makes it possible to solidify an entire object at once. Others, such as Liqtra’s seven-nozzle technology, are conceptually less broad. Material developments are often linked to specific process improvements. It is impossible to keep track of and discuss all of the developments, but examples are provided to give an impression of the changes that are happening.
