Why injection moulding tools from the 3D printer?

Dirk Zacharias | 2. August 2019

With the aid of 3D printing, injection moulds can be manufactured at up to 80% lower costs. As a result, 3D-printed moulds are particularly interesting for small batches and samples, and can be commissioned for a quantity of 1 or more. The complete iglidur range of 50 materials is available for the maintenance-free plastic plain […]

How does a 3D printer work?

Dirk Zacharias | 2. August 2019

Basically, a 3D printer works much like a well-known 2D printer that applies ink to a paper by means of a jet or laser. The 3D printing is an additive process in which material is gradually added layer by layer to create a three-dimensional model. There are several methods in 3D printing that work slightly […]

Dimensional deviations in the various 3D printing processes

Dirk Zacharias | 1. August 2019

SLA (stereolithography):  ± 0.2 % (with a lower limit of ± 0.2 mm) The stereolithography (SLA including DLP), together with Polyjet, is the most accurate method. The diameter of the laser is usually between 100 and 150 µm. This is much less compared to the FDM method.   This results in fewer tolerances and the […]

Avoidance of tolerances in design & orientation in 3D printing

Dirk Zacharias | 1. August 2019

Depending on the alignment of the component during printing, different results may occur for the surface. Depending on the printing process, this more or less influences the quality of the finished component. Therefore attention should be paid to the alignment while printing, whether there are certain functional areas in the component, where a smoother surface […]

Reworking tolerances

Dirk Zacharias | 1. August 2019

Depending on the requirements of the finished component, 3D printing also requires a certain amount of reworking of the printed parts. For example, support structures or masses have to be removed manually. Likewise, the parts are subjected to various methods of blasting or vibratory finishing as required. Manual sanding may also be required to get […]
