If that plane were flat relative to the bottom of the model, this wouldn’t be a problem. My Porygon model is pretty good, however, the model does have one shortcoming: the top plane of the head is ever so slightly inclined. If you want a great example of how to code polyhedrons in OpenSCAD, here you go. This is my response to 2015’s spasm of low-poly Pokemon, and it’s actually made out of computer code. The output for Slic3r’s old variable layer height settings Electric Soldier Porygonįor this example, I’m going to use a model of my own design: the ultimate low-polygon Pokemon. The results are the same, but tweaking a model isn’t as easy as the Prusa edition of Slic3r. Setting variable layer heights in the old versions of Slic3r are as simplistic as setting a Z axis offset and the layer height for those layers. The settings for variable layer height are right there, easily accessible from the plater. To be fair to Slic3r, variable layer slicing has been around for a while. This version of Slic3r was just released, and now it’s time for the hands-on. So far, though, there’s no good automated solution for variable layer height slicing, and the tools for manual configuration of variable layer height slicing are terrible.įor the past few months, Prusa Research has been working on their own edition of Slic3r that includes an easy to use interface for variable layer height slicing. Recently, Autodesk’s Integrated Additive Manufacturing Team released Varislice for automatic generation of variable layer heights on a 3D printed object. 3D printers weren’t exactly common back then, though. Yes, there were a few papers from a decade ago laying the conceptual foundations of variable layer height slicing. Think of it as printing the neck of a bust at 0.3mm layer height, and the face at 0.1mm. Basically, if you’re printing something without much detail, you don’t need small layers in your 3D print. One of the best solutions to this we’ve seen is variable layer height slicing. This balance between print time and print quality has, for the last few years, been completely ignored. Now, just about any printer can produce fantastic models at a very high layer height, but no one wants to wait several days for the print to finish. However, direct drive extruders are better for many filaments, and the decision on what printer to build ultimately comes down to a choice between speed, build area, and the ability to print in exotic filaments.Įven in slicing a 3D model, a 3D printing enthusiast must balance the quality of a print versus how long the print will take to squirt out of a nozzle. Generally, you don’t want a lot of mass on your tool head, as that can lead to ringing and other mechanical artifacts on your print. 3D printers are an exercise in compromise.
