Dyndrite incorporates OVF open-source information format inside ADK and LPBF merchandise

Dyndrite has introduced its assist for the Open Vector Format (OVF) developed by RWTH Aachen College Chair Digital Additive Manufacturing DAP inside its Dyndrite Laser Powder Mattress Fusion (LPBF) software program.

OVF is an open-source information format developed by RWTH Aachen College scientists to offer a streamlined, info-rich information hyperlink between the digital and bodily course of. It’s stated to allow a sturdy and environment friendly manufacturing course of, whereas additionally providing ‘a number of benefits over current codecs like CLI and 3MF.’

Based mostly on the broadly used serialisation expertise Protocol Buffers (Protobuf), which handles the switch of knowledge from advanced structured information objects right into a byte system, OVF offers an open and versatile format for controlling a laser with a galvanometer scanner. RWTH College says it helps scanfield arrays in addition to extra machine axis controls, whereas additionally providing a compact binary storage of all information and versatile ahead and backward compatibility.

LPBF process-relevant metadata round manufacturing parameters, laser powder and scanning pace could be effectively transported alongside the method chain with OVF, with a broad portfolio of instruments that cowl file conversion to OVF information; integrity verify routines; and contour, parameter and layer checks can be found on the OVF Github.

Dyndrite believes the event of OVF at RWTH Aachen College solves an issue in that there isn’t any normal format for the output information of LPBF processes. By partnering with RWTH Aachen College, Dyndrite has integrated OVF export functionality straight inside its Software Improvement Equipment (ADK) and LPBF merchandise.

“Dyndrite’s core imaginative and prescient is to vary how geometry is created, reworked and transmitted on a pc,” commented Harshil Goel, Dyndrite CEO. “The OVF format is a really logical step in the direction of bettering how advanced structured toolpath information could be transmitted in a performant and compact method. Solely by open supply advances like OVF can additive manufacturing enhance its adoption, democratisation and industrialisation fee.”

“We developed OVF as a result of there was no passable format for two.5-dimensional information that was each open-readable and contained extra info apart from the precise toolpath,” supplied, Moritz Kolter, Group Supervisor Digital Manufacturing, RWTH Aachen College Chair Digital Additive Manufacturing DAP. “OVF, nonetheless, is ready to course of information after slicing in a performant, readable method and can be capable of hyperlink different info akin to 3D half information or metadata. That is particularly vital so as to have a totally linked end-to-end information chain that can drive the industrialisation of AM. For instance, we use it for superior manufacturing planning or half orientation algorithms to additional promote the sustainable and environment friendly use of applied sciences akin to LPBF.”
