Multiple looping constructs that depend on what you are going to do with the results, not on how you want to loopįortunately, Matt Farrell has written scad-clj, an OpenSCAD DSL in Clojure.

  • Unclear variable binding rules (multiple passes are made over the code and the results of changing a variable may affect things earlier in the code unexpectedly).
  • Strange function application syntax (parameters in parens after the function name with an expression or block following the closing paren).
  • This isn’t a beat-up-on-SCAD post, but a few of the things that irked me were: OpenSCADĪ couple of friends suggested OpenSCAD, which is touted as “the programmers’ solid 3D CAD modeler.” It provides a power set of primitive shapes and operations, but the language itself leaves a bit to be desired. Also, it is really designed for interactive modeling and I need something that I can programmatically tweak. It’s an amazing beast, but after a few hours of tutorials it was clear that it would take a while to get proficient with it. When I first started trying to make models a month ago, I tried Blender. If you like programming and want to step out of the world of bits and bytes with your creations, this book is certainly the start of an exciting journey of discovery.I’ve been doing some 3D printing for my next keyboard project and I’ve got a workflow that I’m pretty happy with that I’d like to share.

    And although it is not a book about 3D printing, you also get some tips on how to make practical models that don't make it too difficult for your 3D printer. What you do get is a thorough explanation of all kinds of tools, including real-life examples that you can definitely use in your own 3D printing projects, such as rounded objects and cut-outs for screws and nuts. So here's a tip: the book provides many details, so read it carefully so you don't get lost, particularly because the author provides narrative and anecdotal summaries. When I got to end of the book, I wondered if I would be able to work with OpenSCAD in a structured way. The author is clearly well experienced with 3D modeling, as is evident from the in-depth explanation in which he often provides very concrete points for attention and solutions. Over the course of the book, he explains how to model some practical objects in OpenSCAD, such as a knob for an oscilloscope, a cloth hanger for the wardrobe and a holder for a soap dispenser. Tam Hanna gives us an intensive insight into this approach in his book Technical Modeling with OpenSCAD (Elektor 2020). OpenSCAD has a different approach: it is not an interactive modeling program, but a kind of 3D compiler that reads a script with code and converts it into a 3D model. For programmers and engineers, these programs provide a way of working that is opposite to their way of thinking. Traditional 3D design programs target designers and artistic minds. You need to learn how to use a 3D design program to make models that you can send to your 3D printer. But designing those objects remains a skill that you will not master overnight. Simplifying the ability to make all kinds of objects yourself.
