With the assist of GrabCAD Print, a cloud-dependent CAD software package, Stratasys 3D printers can now go instantly from CAD to print, therefore taking away the conversion to mesh file move to streamline the workflow.
Mark Walker, Stratasys’ Direct Software package Solution Manager spelled out, “For design and producing engineers, one particular of the most irritating procedures is ‘dumbing down’ a CAD file to STL structure – only to involve subsequent re-injection of structure intent into the STL printing system.”
“This computer software is engineered to do away with this complexity, permitting designers decrease iterations and layout cycles – receiving to a superior-excellent, reasonable prototype and last section faster than ever right before.”
GrabCAD Print Sophisticated FDM
GrabCAD is a Massachusetts-based startup owned by Stratasys. In 2016, the startup launched the GrabCAD Print to make the workflow of Stratasys 3D printers a lot more economical. The most up-to-date addition in this exertion is the Advanced FDM element, which can slice CAD types right for 3D printing certification, generating the production process leaner.
GrabCAD Print is now used by companies this sort of as McLaren and Eckhart, an industrial automation corporation.
Robert Heath, Eckhart’s Additive Producing certification Application Engineer, described, “GrabCAD Print Highly developed FDM’s geometry-based mostly workflows have permitted us to fine-tune portion builds – meeting application needs and system parts additional rapidly than we could prior to […] The seamless changeover of relocating a build involving applications is quick and intuitive.”

A new way of slicing
All CAD documents will need to be translated into a mesh file prior to they are sliced for 3D printing certification. Since the introduction of 3D printing certification engineering in the 1980s, mesh documents like .stl and .obj have been the common for developing 2D slices (or 3D printer toolpath). Hence, there is often a step in between the CAD file and the gcode that is ship to the 3D printer.
A CAD file has a higher amount of detail about the component geometry, changing it into a mesh file makes several problems, these types of as decline of geometrical info. Troubles like these are set in software program like Netfabb. Industry experts in the 3D software marketplace have experimented with to counter these types of troubles. GrabCAD Superior FDM function is a further move in this course.
It allows consumers build toolpath (gcode) for 3D printing certification specifically from the CAD product. This way there is no need to have to deal with all the challenges of .stl (or other mesh) file formats.
Dave Hewitson, Swift Prototyping Programmer at McLaren mentioned, “Advanced FDM has proved priceless in strengthening our aspect processing time. When processing a incredibly huge range of tools and fixtures in a very time pressured ecosystem, it was essential to be certain stronger tool regions were being proper to start with time, every time.”
From CAD to print
GrabCAD Innovative FDM aspect now supports all of Stratasys Fortus methods (except the 250 mc and 360mc), F900 and F370.
Owing to the nature of workflow of the Advanced FDM (i.e. from CAD to 3D print), .stl and .obj are not supported. Nevertheless, numerous other qualified CAD file formats like IGES, Move, CATPART, and SLDPRT. The sliced file can be exported to the cloud or to the 3D printer as a .cmb file.
Assist for this sort of sector normal file formats adds another layer of efficiency to the CAD to print workflow. As Hewitson stated:
“Advanced FDM negates the requirement for numerous packages – building a much more streamlined approach. It’s also allowed us to much more efficiently manage the composition of finish-use car parts, one thing that was beforehand extremely hard with the solutions we experienced in hand. This implies we can get better parts to the keep track of speedier.”
