Catalyst Ex Software

Stratasys, Ltd. Is an American manufacturer of 3D printers and 3D production systems for office-based rapid prototyping and direct digital manufacturing solutions. Engineers use Stratasys systems to model complex geometries in a wide range of thermoplastic materials, including. May 18, 2017  UPDATE: Catalyst software has been replaced with GrabCad Print.

Way back I did a project involving 3D printed reproductions for visually impaired visitors of a science museum. The models were created using photogrammetric reconstruction, based on hundreds of photos of the large-scale exhibits. For production of scaled down tactile models, we chose a (a system) because of it’s relatively durable output and simply because we had one available for a comparably low printing fee. After many hours of correcting, re-sculpting and tweaking around the digital models, I went to the catalyst ® ex program to create the toolpaths for the printer. The interface is really simple. You choose an containing your 3d model, choose the orientation, scale and position on the building platform, and some basic build options (layer resolution, model interior fillings and type of support structure) and it generates the data for the machine stored as a CMB-File. One thing that annoyed me is that the program only reads STL files, which is aa really terrible 3D file format.

Nobody knows why the 3D printing guys back then invented this stupid format not containing any connectivity information or vertex indices. Blank tabelj ucheta rabochego vremeni uchitelej. They just could have chosen any then established format from the computer graphics of CAD communities. But well, if it is the standard, I will stick with it, as long as I don’t have to read it back.

But, what annoyed me even more is that there is no possibility to preview the 3D printed version. Before starting the print job, I wanted to make sure that the model was nice enough, for the printing resolution, and that the printer did not introduce strange artifacts (e.g. Staircase artifacts on slightly uneven horizontal surfaces). After all, our largest print took over 36 hours, and despite the low printing fees, it is not that cheap at all. So simply doing a test-print was not an option.

Unfortunately, Stratasys does not offer any kind of 3D preview. Catalyst ® ex only shows the 2D footprint on the building platform and statistics about the amount of building material and time needed. The co-installed utility program CMB View allows closer inspection of the CMB file (amongst other file formats). This is basically a slice viewer, displaying toolpaths of one build-slice. Using the home, end, page-up and page-down keys, you can conveniently step through all slices. In the (somewhat hidden) CMB Viewing Options pane (menu View/Controls/CMB) you can choose among the different kinds of toolpaths to display.

In addition, the View/Info/CMB menu shows some meta-information. In fact, as it turned out, the CMB Viewer allows to browse all information stored in the CMB files. The slice-viewer can actually display the slices in 3D and may be rotated freely. With the “Show one layer only” option (CMB Viewing Options) turned off, you can even view all slices simultaneously. So in order to see the 3D shape, you may turn off all options except part exterior and view all layers concurrently.
