Of course it can, and while non-planar 3D printing is nothing new, over at CNC Kitchen shows us a literal twist on the concept, with this four-axis non-planar printer. To have the X- and Y-axes working together to make smooth planar motions while the Z-axis just sits there waiting for its big moment, which ends up just moving the print head and the bed another fraction of a millimeter from each other just doesn’t seem fair. It always seemed to us that the Z-axis on a 3D printer, or pretty much any CNC machine for that matter, is criminally underused. What will you build with this tool? If you don’t like arcs, check out conical slicing or non- planar slicing instead.Ĭontinue reading “Arc Overhangs Make “Impossible” 3D Prints” → Posted in 3d Printer hacks Tagged overhang, slicer, support material Since the code is on GitHub, maybe people familiar with the mainstream slicers will jump in and help make the algorithm more widely available and automatic. It probably will never be a default setting, but it would be a nice option for parts that can benefit from the technique. Like, we hope this gets picked up by mainstream slicers. You don’t need any special hardware other than good cooling. There can also be a bit of warping if features are on top of the overhang. We admit the surface looks a little odd but depending on why you need to print overhangs, this might be just the ticket. We’ve seen a similar technique handcrafted with fullcontrol.xyz, but this is a Python script that semi-automatically generates the necessary arcs that overlap. There’s a third video below that shows some recent updates to the tool. Because the arcs overlap, they support the next arc. The basic idea is that you build surfaces “in the air” by making small arcs that overlap and get further and further away from the main body of the part. If you want a quick overview, you might want to start with the video first. In addition to the video from, there’s also a video from below that covers the technique. It also helps to print at a cool temperature with plenty of fan and a slow print speed. The key is to build the overhang area with concentric arcs. If you want to see some more printers with more than 3-axes, check out the RotBot or Open5X.Ĭontinue reading “5-Axis Printer Wants To Design Itself” → Posted in 3d Printer hacks Tagged 3d printer, 3d printing, 5-Axis, duet controller, Duex, generative design, genetic algorithm, parametric, reprap, slicer, slicingĪn accidental discovery by allows overhangs on FDM printers that seem impossible at first glance. With how fast AI is evolving, perhaps soon this printer will be able to completely design itself? For now, you’ll have to download the files and try it yourself. Since the generative algorithm uses parametric inputs, it should be possible to to have a Gen5X generated based on the vitamins you may have already. The Gen5X uses the 5 Axis Slicer from DotX for slicing files and runs a RepRap Duet board with Duex expansion. Since this is a generative design, future variants could look different depending on which parameters you have the computer optimize. Starting with “a set of primitives… and geometric relationships,” ran the system through multiple generations to arrive at its current design. While 5-axis printing is old hat in CNC land, it remains relatively rare in the world of additive manufacturing. The generatively-designed Gen5X printer by brings the design step of that process closer to reality. RepRap 3D printers were designed with the ultimate goal of self-replicating machines.
