![]() ![]() Apart from cutting, laser cutters can also raster or etch designs onto work pieces by heating up the surface of the workpiece, thus burning off the top layer of the material to change its appearance where the raster operation was performed. Laser cutters use a thin, focused laser beam to pierce and cut through materials to cut out patterns and geometries specified by designers. I'll add the link to your tutorial in a pinned comment on the YouTube video, as well as the corrections and improvements.A laser cutter is a prototyping and manufacturing tool used primarily by engineers, designers, and artists to cut and etch into flat material. ![]() Here's a picture of one of the things I made using your custom feature: They absolutely fit together, but I think that the overall kerf compensation method would have made it work even better. Now that the pandemic seems to be a bit better under control (or at least better understood) in Seattle, the university has started to re-open maker spaces as long as social distancing is observed, so I was able to finally go and laser-cut some projects. ![]() The tutorial you made is very clean and well-put-together! Also, thanks for the suggestions for the slip fits. That assembly-based method with in-context design looks super useful. Also, the kerf compensation custom feature seems like a much cleaner and more accurate way to get the physical result to match the intent of the 3D model. Thanks for the kind words and great feedback I absolutely should have been more clear with the prerequisite parts I think I'll put together some visual examples of what the custom feature can accept once I have time to make an updated version of the tutorial. ![]() That same tutorial has some recommended parameters for a typical laser and 3/6mm ply that give pretty good slip fit joints that sit flush.Īgain, great video tutorial, just wanted to leave some thoughts here in case it helps you or anyone else use this set of FeatureScripts.ĭefinitely agree with you on drawings being the best way to go - I tried doing the sketch to DXF thing the first time I made this feature and rapidly figured out how annoying it was when I made any changes that resulted in a change in the number of regions.If you don't have repeated subassemblies, then you'd have part studio -> laser joint -> kerf compensation -> auto layout -> drawing(s). I'm not doing the thicken here because I wanted to illustrate how you might want to do a laser-cut structure that has subassemblies, so my workflow is part studio(s) -> assembly(ies) (or assembly with copied subassemblies) -> in-context copy all in place -> laser joint -> kerf compensation -> auto layout -> drawing. You might also find a tutorial I did for a class at Stanford interesting for some ideas.I'll go in and make sure adaptive pin sizing also remembers previous.The way you're doing it does work, it just leaves other aspects of the part small by half of a kerf. The intent of the allowance features is if you want to adjust the nominal fit of the joint. If you don't do this, assembling a joint so that the parts touch means that the ends of the pins end up overlapping by your kerf (also things you thought were 25mm end up as 24.8). The reason for doing it this way is so that all sides of the part are compensated, and it comes out to nominal size. My own workflow is to drop in a kerf compensation feature after doing the auto layout to do all of the compensation at once. At one point you add allowance internal to the joint of half the kerf.You mention the prerequisite is multiple intersecting panels of a uniform thickness, which is maybe a little ambiguous - only each part needs to be planar, different parts in the single joint can have different thicknesses.Hey awesome video! I'm not sure how I missed this given that you tagged me in the original post, but this is super clear! ![]()
