If you’ve ever been lost in the midst of all the3D printing technologies, you know how hard it is to get a grip on the different machinery, applications and companies involved.
Patent disputes, crafty marketing teams and feuds amongst inventors have led to a point where identical technologies go by different trademarks and are limited in their applications because of potential infringements. Many “new technologies” — actually trademarks — are presented as revolutionary, when they are in fact similar or the same as existing systems.
For the industrial designer or engineer it’s important to have a grasp on thesetechnologies because they can tell you a lot about possible applications and limitations from the outset. This is generally not an easy thing to do. To shed some light on the situation, and help you understand the different technologies, here’s an overview to get you started.
The overview contains all the main additive manufacturing technologies of today, starting with process descriptions and guiding through all the individualtechnologies and material options, ending with the key industry players.
Using the overview, it can be particularly interesting to have a look at where new 3Dprinting technologies fit into the grand scheme of things and what can be expected of their applications and possible limitations.

A little more than a year ago, Joseph M. DeSimone, a chemistry professor from UNC Chapel Hill, walked onto a TED conference stage and left the audience in complete awe. On stage he unveiled a technology dubbed Continuous Liquid Interface Production (CLIP) that promised to be up to a 100 times faster than comparable 3D printingtechnologies and capable of creating smooth, strong parts, equivalent to their injection-molded counterparts. By the end of the 10-minute presentation, a solid object had risen from the bath of the obscure 3D printer he had brought with him.
