Based on simulations and prototype production, the influence of an additive manufactured injection molding tool cavity on the manufacturing process was investigated. Due to the improved cooling performance, the cycle time can be reduced by approximately 10 %, whereas at the same time, a high dimensional stability of the polybutylene terephthalate (PBT) component can be achieved.

In the center of the image, the two halves of the injection molding tool can be seen. The inner cavities were created by additive manufacturing.  The contributors from left to right are: Nicolas Büttner, Dominik Lawatsch, Dr. Sebastian Neubauer (all Valeo), Christian Hellmuth, Michael Vosswinkel (both Hofmann). Pawel Uchyla (Valeo) is missing.

Molds for orthoses are usually machined. That is not optimal – neither for the patient nor for the manufacturer. Within the scope of a study, Lehmann & Voss therefore investigated whether 3D printing is an alternative – both ecologically and economically.

Robotics meets additive manufacturing: when Kuka robots produce furniture, they do not take work away from carpenters by any means. The chair and bench modules made of recycled hospital waste, named Twine – designed by HagenHinderdael in London – are a novelty in the world of furniture, engineering, and recycling.

Additive manufacturing has the potential to manufacture tablets individualized for the particular patient, and thereby further digitalize the pharmaceutical industry. In medication development, the properties of a tablet, such as its shape, dosage or release of the active substance, can be individually tailored – by making just a few changes to the digital 3D print file. Merck scientists have used a Freeformer for their lab tests.

Merck researcher Dr. Thomas Kipping (right) and Nabil Lamrabet value the advantages that the Freeformer offers as an open system.

It is a hot runner nozzle such as had never been seen before Fakuma 2021: with a honeycomb structure on the outside and, in the nozzle interior, integrated insulation gaps manufactured in one part by the additive SLM process, in which even the fastening nut is captively printed on the nozzle body. The pride of the concept is the special algorithmic modification of the nozzles for any application case.

A mold-making job with up to 30 nozzles is processed in the SLM machine in about 24 hours.

The use of recyclates confronts companies with new requirements in the processing, bonding, printing and labeling of materials and components. Atmospheric plasma technology, in which Plasmatreat GmbH has specialized, has established itself as a key technology: it often makes the use of recycled plastics possible in the first place – and also proves to be the means of choice on the way to more environmentally friendly, more resource-efficient production processes.

When using Openair-Plasma, the plasma jet works in a location-selective manner and follows the component geometry with millimeter precision. During the plasma treatment, very little heat is generated, so that the treated components remain dimensionally stable.

Over the four trade-show days in November, Formnext 2021 transformed the metropolis of Frankfurt am Main, Germany, into an international innovation center of global additive manufacturing and modern industrial production. At the plastics side, some of the focuses were on the manufacture of voluminous parts, the use of injection molding pellets as a material basis, and the processing of high-performance plastics.

Production is becoming ever more flexible, diversified and decentralized. Without doubt, additive manufacturing processes make a crucial contribution to this, also initiating the transformation from production-based design to design-driven production. In this article, the 3D printing service provider FIT outlines a best-practice panorama of current technologies.
