On March 18, 2021, TRUMPF launched a new version of the TruPrint 3000 3D printing system in its online promotion. This medium-format machine uses powder bed-based laser melting technology and can produce up to 300 mm in diameter and 400 in height. Millimeter parts can be printed on all weldable materials, including steel, nickel-based alloys, titanium and aluminum. "We have improved the key parts of TruPrint 3000 to better meet the quality requirements, certification requirements and production process requirements of different industries." said Klaus Parey, general manager of TRUMPF's additive manufacturing department.
The new TruPrint 3000 can be equipped with a second laser, which nearly doubles the production efficiency. Parey said: "The multi-laser option greatly reduces the cost of parts-this is how we help customers achieve mass production." Regardless of the number and geometry of the parts, we have two 500-watt lasers that scan the machine in parallel. The entire molding area can make production faster and more efficient. With the automatic multi-laser calibration option, the system can automatically monitor the multi-laser scanning area during the manufacturing stage and align them with each other. Scanning a complete contour by the same laser will not produce any splicing welds. This is also the technical guarantee for such excellent quality of multi-laser printed parts.
Due to the improved inert gas wind field and molten pool monitoring function, the quality of parts is improved
The experts at TRUMPF have changed the way the inert gas flows in the TruPrint 3000 forming chamber. Now, the way the inert gas flows through the printing area from back to front is more stable and uniform. In addition to improving the quality of printed parts, it also allows the operator to remove excess powder from the parts in the machine. The previous model required the operator to take out the parts and carry out the powder removal work in a separate station. The new machine is designed to process the powder in a protective atmosphere and use inert gas to prevent the powder from being contaminated during the printing process, which is a big advantage for industries such as medical equipment.
The new TruPrint 3000 can also be equipped with a molten pool monitoring function, which can automatically monitor the thermal radiation and other indicators of the molten pool during the 3D printing process to ensure the quality of the parts. Special sensors in the laser optics also continuously monitor the molten pool. We have special software that compares the read data with the data of the reference workpiece stored in the database, and displays any deviations in the form of images, such as the molten pool is too cold or too hot. The molten pool monitoring provides the operator with the information needed to detect defects in order to take the necessary measures.
TruPrint 3000 can be flexibly adjusted according to customer requirements
Different industries and different parts have different production requirements, which is why TRUMPF provides flexible production solutions. Parey said: "The new TruPrint 3000 allows us to customize the process chain to perfectly match each customer's manufacturing process." In addition to the above-mentioned solution for removing powder inside the machine, TruPrint 3000 also provides a model that can replace the cylinder. With external unpacking and sieving station. This model has multiple advantages, enabling the machine to better meet the specific needs of customers, cope with the continuous increase in output, and minimize downtime through parallel production.
