In an effort to make its 3D printing methods smarter and extra productive TRUMPF not too long ago took the chance of the Formnext commerce honest in Frankfurt to current a collection of latest software program, sensor (together with soften pool monitoring and gasoline stream) and automation options designed to enhance the effectivity of 3D printing. For instance, the brand new TruTops Print software program now combines a number of knowledge preparation and planning steps that beforehand required a number of completely different software program instruments. “Z-segmentation” is among the most fun options of the brand new TruTops Print software program. This function boosts the productiveness of the system by dividing elements into completely different segments and assigning completely different parameters to every section based mostly on the required half high quality. This permits the 3D printer to generate thicker or thinner layers for every half relying on the significance of the respective section. This versatile strategy to printing will increase the productiveness of the system with out diminishing half high quality.
TRUMPF teamed up with expertise supplier Module Works to develop the brand new TruTops Print software program. As a part of their strategic partnership, improvement engineers from the 2 corporations joined forces to adapt the TruTops Print software program to the particular necessities of TRUMPF 3D printing methods and package it out with an intuitive person interface.
“This new software program permits us to supply our clients a extra tailor-made strategy to working our TruPrint 3D printers,” mentioned René Kreissl, who’s liable for the additive manufacturing enterprise at TRUMPF. “We’re making it far, far simpler for purchasers to make the journey from an preliminary thought for a component to the ultimate product – and that’s a good way to enhance the general attraction of additive applied sciences. Module Works is very skilled in digital manufacturing, so that they had been the right selection of accomplice to assist us develop the brand new software program.”
New gasoline stream and monitoring
As a part of its efforts to make its machines much more sturdy and enhance half reproducibility, TRUMPF has spent latest months creating a brand new gasoline stream idea. This optimizes the stream of protecting gasoline by the construct chamber, which is a very essential facet of the system, particularly through the printing course of. The brand new idea ensures homogeneous stream situations to make sure the environment friendly elimination of smoke from the construct chamber; this creates the type of persistently good course of situations that permit the laser to carry out its work undisturbed. All of the latest-generation TruPrint 3D printers include this new gasoline stream idea. TRUMPF has systematically examined how the stream idea impacts the robustness of the method and has validated it on all its new-generation machines.
One other key focus on the TRUMPF Formnext stand was the brand new TruPrint 3000 medium-format machine. Outfitted with two 500-watt lasers, the TruPrint 3000 makes use of powder-bed-based laser melting to supply elements as much as 400 millimeters tall and as much as 300 millimeters in diameter. It additionally comes with a standout quality-assurance function within the type of soften pool monitoring. This depends on particular high-speed sensors within the machine optics that routinely monitor the soften pool through the printing course of. Clever evaluation software program determines if the soften pool is simply too chilly or scorching and presents a graphical show of any deviations from a reference construct job, thereby giving operators the knowledge they should detect, analyze and rectify errors. The machine additionally incorporates a powder-bed monitoring function which makes use of a high-resolution digicam and computerized picture processing to observe the powder mattress within the construct chamber and routinely detect issues reminiscent of faulty powder layers.
The TRUMPF digitalization options for 3D printing additionally embody a normal situation monitoring module that delivers the related KPIs, in addition to an choice for purchasers to manage their machines through distant entry by interfaces such because the industry-standard OPC UA interface.
Greater productiveness through elevated automation
TRUMPF continues to include a spread of automation options in its 3D printing applied sciences. For instance, the TruPrint 5000 medium-format machine may be set to begin the manufacturing course of routinely. As quickly because the construct cylinder is positioned within the system, it strikes routinely to its set-up and dealing place. The built-in zero-point clamping system is the premise for downstream course of steps reminiscent of EDM, milling and turning. It connects the substrate plate routinely with the piston within the cylinder, eliminating the necessity for guide work steps, reminiscent of tightening screws.
Subsequent, a transport system within the course of chamber units the construct and cylinder covers to a relaxation place, and the manufacturing course of begins autonomously. Within the subsequent step, the lasers calibrate themselves and the construct course of begins routinely. Due to the precept of interchangeable cylinders, the construct cylinder can exit the machine with the completed elements whereas the construct chamber maintains an inert atmosphere utilizing a shielding gasoline and is ready to begin instantly on the subsequent job. This reduces downtime and non-productive time and will increase the productiveness of the 3D printer.
One other helpful function is the automated monitoring of the scan area, which is the world by which the laser works within the construct chamber. This improves the reliability of the method by measuring the place of the laser beams, checking them in opposition to the software program and re-aligning the beams the place mandatory.
