With a strong foothold in the machine tool, laser technology and electronics market, Trumpf has gone on to become one of the leading players in the sector. Along with a rich experience of 20 years in the additive manufacturing field, the firm also spearheads in this significant future technology. The company is constantly working towards providing state-of-the-art technologies that are accurate as well as cost-efficient.

Trumpf @Formnext 2018

At this year’s global Formnext exhibition, Trumpf is all geared up to showcase some of its recent 3D printing solutions to the numerous visitors attending the trade show. With a special focus on additive manufacturing, the event will be held from November 13–16, 2018 in Frankfurt, Germany and will also exhibit the next generation of manufacturing technologies. Trumpf will be displaying the automated 3D printing solution – TruPrint 5000.

This system comprises a Laser Metal Fusion (LMF) technology and works according to the multi-laser principle, with three lasers joining forces to melt the component's geometry in the powder bed. The machine is also capable of preheating up to 500 degrees Celsius making it the maiden system to process heat-resistant materials such as carbon steels. This function requires less reworking and also proves advantageous for the components as it improves the machining quality of materials such as titanium and also reduces stress in the component.

Automated method of handling lids

In addition to this, the company will also demonstrate the new automated method of handling lids aboard the TruPrint 5000 for build and supply cylinders. Equipped with two lids, the TruPrint system also ensures greater safety. The first lid is positioned on the processing chamber and conserves the inert gas atmosphere from one printing job to the next while the second lid prevents powder loss during transport. The plus point of this process is that now the operator does not have to manually replace both the lids as compared to the processes of the past.

The firm has replaced the recoater's applicator with its very own developed carriage. The carriage spreads the powder coating in the build chamber during printing and the insert installed on the carriage ensures that the lids are kept in place. The supply cylinders ascend independently and latch their lids into the processing chamber's ceiling. This places them beyond the laser's scanning range, where they can remain until the process runs its course.

Melt pool monitoring tech process

Apart from the unique features of the TruPrint 5000 system, Trumpf will also reveal the functioning of the melt pool monitoring tech process. This sensitive process ensures that high quality is maintained. For instance, minor fluctuations often lead to errors. In this technique, diodes in the printer capture the light emitted during the process to monitor the melt pool's quality. The IT system then compares these values with data sourced from a reference component, and graphically displays anomalies such as a cooler or overheated melt pool. The machine operator can see the flaw straightaway and halt the process. This assessment takes place after each coat is applied, as does a similar assessment for powder bed monitoring.

These are just some of the innovations that will be exhibited by Trumpf at Formnext. To get an in-depth view of the latest technological revolutions do visit the show!
