Dyndrite Announces Support for OVF Open Data LinkNovember 3, 2022
Dyndrite has announced support within its Dyndrite laser powder-bed fusion (LPBF) software for the new Open Vector Format (OVF), an open-source data format developed by scientists at RWTH Aachen University Chair Digital Additive Production DAP in cooperation with the Fraunhofer Institute for Laser Technology ILT. OVF provides a streamlined data link between the digital and physical process, enabling robust and efficient manufacturing processes and offering a number of advantages over existing formats, such as CLI and 3MF, according to Dyndrite officials. It reportedly provides an open, flexible format for controlling a laser in combination with a galvanometer scanner, and supports multi scanfield arrays as well as additional machine axis controls.
“We developed OVF because there was no satisfactory format for 2.5-D data that was both open-readable and contained additional information besides the actual toolpath,” explains Moritz Kolter, group manager of digital production at RWTH Aachen University Chair Digital Additive Production DAP. “OVF can process data after slicing in a performant, readable manner and also can link other information such as 3D part data or metadata. This is especially important in order to have a fully linked end-to-end data chain that will drive the industrialization of additive manufacturing (AM). For example, we use it for advanced production planning or part-orientation algorithms to further promote the sustainable and efficient use of technologies such as LPBF.”
A standard format for the output data of the LPBF process currently does not exist, according to Dyndrite officials. Instead, they explain, numerous formats, either proprietary or developed for other production processes, are used—thus they lack the relevant information for production using LPBF. OVF reportedly solves this challenge.
“The OVF format is a very logical step towards improving how complex structured toolpath data can be transmitted in a performant and compact way,” says Harshil Goel, Dyndrite CEO. “Only through open source advances such as OVF can AM improve its adoption, democratization and industrialization rate.”
