So there are a couple more headlining features that you’ll see everyone talking about, but before I also talk about those, I want to point out one easily missed, but really neat new feature that I think may have been a byproduct of the new auto support painter. Fewer design restrictions, more creative use of the geometric freedom that 3D printing brings without having to spend half an hour peeling your part out of a block of support material? Yes please. I’ve seen speculations whether designers are now going to start factoring this in and mechanical and organic parts are just going to be printed with a bit of support from now on. I didn’t see any improvements in how well the tree support material worked with the auto painter, which I guess really wasn’t the point in the first place, but the part also didn’t look worse – and I think that is a huge win for using 1/3rd of the material, and being much easier to remove. So final thoughts on support material: This is really cool. If you want to try the automatic support painter, make sure you also set the support mode to “enforcers only” or you’ll actually get more support material instead of less. So for example, bridges, if they’re short enough, get no support at all, and if they’re above a certain length, they get a bit of support material every now and then, and then essentially print as a bunch of shorter bridges between those. Now, thanks to new AI technology – no, it doesn’t use AI, it’s just smart programmers, I think – it detects which areas need supports and which don’t, and it does it a lot intelligently than the classic “support anything that has an angle over 60° from vertical” approach. PrusaSlicer has long had support material painting where it would only generate support material for the areas that you explicitly marked. You, can, of course, configure everything about these supports to your liking.īut the new supports actually work best with another new feature, and that is automatic support painting. If you look at these branches, they do widen up towards the bottom, so they don’t fall over, but they also branch out towards the top, so one single printed column can actually support a good bit of area. 2.6, it’s using almost 2/3rds less filament for the support material. These branches are printed with limitations to how steep they can be so that they still print reliably, they’re just one wall thick for most of the time, so even though they are quite rigid, they weigh barely anything, in this case using PrusaSlicer 2.5 vs. Tree support goes outside the part if it can, but if it must, it will still fall back to anchoring itself to the part. That can leave scars, especially on darker material, and it’s pretty often awkward to remove from tight spots like holes and little cubbies. I’ve also seen it called “tentacle support”, that works, too, so instead of building these sparse blocks just vertically straight up to the area that needs supporting, these can now snake around your part from the build plate and reach into spots that otherwise would need to have support material printed on top of the part itself. ![]() Okay, first big feature – support material. For me, it was working flawlessly, but in any case, it uses a separate config directory, so it’s not going to mess up your PrusaSlicer 2.5 profiles. Open Source is pretty beautiful when it works!Īlright, before we start, this is a pre-release piece of software, bugs aren’t just possible, they are expected. Some of the new features we’re going to look at are adapted from other open-source slicers and then fine-tuned for PrusaSlicer, and, vice-versa, I hope that other slicers pick up the rest of the features, too. Of course, this isn’t just for Prusa machines, you can use PrusaSlicer with any 3D printer that speaks gcode, in fact, the 2.6 release now out-of-the-box has tuned profiles for the new Elegoo Neptune series, Creality Sermoon and Ender-5 machines, the AnkerMaker, and even for Print4Taste’s food printer, a printer I’ve reviewed here on the channel, too. This one is 2.6, alpha 3 at this time at the time of me recording, and it brings with it some features that, each one on their own, are just, nice, but when you put them all together, it makes for an overall well-improved package. It’s a new year, it’s a new PrusaSlicer release. PrusaSlicer 2.6 might change how we work with 3D files (and you can use it with any 3D printer)! ![]()
