Hinges, gear bearings and ball joints can be manufactured within the same machine and material to reduce cost and manufacturing time. In this article, I’ll explain those different types of impossible designs and how they solve manufacturing issues. Typically, built-in interlocked objects that require no assembly and can’t be disassembled, internal channels that couldn’t be created without 3D printing, etc. What we call an impossible design is a design that couldn’t be created using traditional manufacturing techniques. What is called a 3D printed impossible designs? ![]() Find the other episodes here!īenefits of 3D Printing: Mass Customizationīenefits of 3D Printing: Integrated Assembly This blog post is part of ‘ Benefits of 3D Printing’ Series, to elucidate with you all the different ways in which producing with 3D printing has many advantages and can change the industrial landscape. Mass customization is the first of these benefits. In the continuity of this series, we are starting a series about the great Benefits of 3D Printing. In a previous series, we explained the principal uses that can be made of 3D printing (prototyping, production, etc.). To continue, we’ll address today another one of the many advantages of 3D printing: the possibility to create “impossible designs”. Select only current object, and scale * 10 PrintingĮnabling the experimental setting "adaptive layers" seems to work well.Ĭan then print the cylinder lowres, and then shape-paths finer, without it taking forever.Last week, we started the 3D printing benefits series with our article on Mass Customization. ![]() If the modifier doesn't work, try to use Mesh -> Clean up -> Fill holes. Select the original object, then select Add modifier -> Boolean and select the cylinder. To make a support it can rotate on, make a cylinder that's 0.5cm diameter and put it through some part of the object. In both cases, it can be nice to select all vertices and recalculate normals. Or select all vertices and press F to generate face, or Grid Fill. Select merge at center from the tool menu. Again extrude, but scale S the new vertices into a small point in the middle, and then Press S, Z, 0 to scale the vertices to same height to get a flat base. Vertices in the Z direction to get the proper height. Select all vertices, extrude E, and move the new Can then either scale S to 0.8, shrinken alt+S to -0.4, or Select the shape again in object mode and press alt + C to convert it back to a mesh, now being more than a thin line. May have to select Minimum and manually twist vertices using Ctrl + T. Convert it into a curve using alt + C.Īdd a bevel object, a line going from (-0.5,0.5) in Y. Next step is to transform the shape into something with width and mass. To join, select two vertices to join and press F. To split, go into edit mode, select a vertex, press L to select all linked, and then P to separate. If the object contains several paths, they may need to be connected or split. Scale it S to 0.2 or so that it's approx 4units = 4cms wide. Import the obj file, select Object -> Transform -> Geometry to Origin to get it somewhere visible. Is also made, fetch it from console by typing copy(window.objFile) and paste it into a text editor. Let circleSquare = Īnd pass it to the intersections-calculator. Make pairs of functions matching the wanted shapes from both viewing directions, ala The SVG will contain a path element with a d attribute. ![]() I draw them in Illustrator using pen tool, from 0px to 100px. *.stl files to be opened in Ultimaker Cura and printed. The obj files are then imported into Blender, and further edited. The various *.obj files are output from the webapp, giving the shapes needed for the illusions to work. svgshapes.ai contains the 2D shapes, that is then exported to SVG-strings for the webapp. Poster contains files and description (in Norwegian) for a poster to accompany the exhibition.ģdfiles contains the end result and vector files. The frontend does the calculations and allow easy visualization of the paths. Run with npm install and npm run watch from root. A circle from one direction, square from other. What you see is an object and the mirror reflection being something else. (What this repo is about) Drag with mouse to look around.

The calculations to make various ambiguous cylinders. Based on the papers by Kokichi Sugihara, I have implemented
