Antialiased openscad rendering

Talpadk's Blog

OpenSCAD rendering. 512×512 OpenSCAD rendering. Recent versions of OpenSCAD is capable of rendering objects/assemblies to images. To the right there is an example of the default 512×512 image quality produced by the command: openscad -o render.png assembly.scad.

How to use Openscad: variables and modules for parametric designs

Tridimake

Part 2/3: Variable and parametric design So far we used only "hard coded" numbers (see the previous part regarding the basics of Openscad). Seriously: when you use Openscad you probably want NOT to use hard coded numbers, but variables instead, as you get lots of advantages in doing so.

With some parametric design you can write OpenSCAD code to generate billions of clocks, each from a random seed. The holidays are coming fast, and you don’t have time to learn how to write parametric OpenSCAD code right now?

Polyholes

Arc shrinkage When a flat strip of filament is bent into an arc there is too much plastic on the inside of the curve and too little on the outside. I decided to investigate this using OpenScad. holes openscad

Day 120 - "Ticket to Ride" trains tray

MakerHome

However, both of those designs use a lot of plastic and take a long time to print. Technical notes: Now that I''m learning to use OpenSCAD I am starting to feel that things like this are a real pain to make in Tinkercad, especially if a lot of tweaking and re-aligning is involved.

Why slicers get the dimensions wrong

HydraRaptor

I now design exclusively in OpenScad using polyholes to get cylindrical holes the correct size as well. I.e. if I work out the volume of plastic extruded from the E number and feedstock diameter and divide it by the length of the line then I get an area.

Beating Tech Obsolescence With 3D Printing

Shapeways Blog

Plug the new measurement into my OpenSCAD designs, and after a bit of that design magic, blood sweat and tears, I worked out that Strong and Flexible Plastic (S&FP) would allow me to use “flex” in the design of the release clip.

Halloween 2015 is all 3D Printed

This was quite a large object, so printing it flat and reforming it with hot water (PLA) or if you print in other plastic's you may need to use a heat-gun. Halloween is getting the 3D printing treatment in our house this year.

Mendel90 GitHub catch up

HydraRaptor

OpenScad I also updated to the latest version of OpenScad. The downside is that the 2D sub-system now uses fixed point coordinates but the rest of OpenScad doesn't. I finally found time to update GitHub with some Mendel90 changes that I have had in the works for a long time.

Printing the Impossible: Evolution of a Fidget Cube

Shapeways Blog

On an SLS/nylon powder printer like those used for Strong & Flexible plastic prints at Shapeways, such “impossible” prints can be printed with great success rates. After a lot of trial and error, I ended up creating the design from scratch in OpenSCAD.

Mendel90 finishing touches

HydraRaptor

I haven''t used any libraries so there are no dependencies apart from OpenScad itself. I also changed the hole depth to allow the same screws to be used as elsewhere and cut away some plastic that wasn''t adding much to the strength.

A simple filament spool holder made in 3 minutes

Tridimake

Easy, with Openscad. The box originally held an assortment of plastic anchors ( large review here ). Here is a short post on yet another low-tech but functional tool (the last one was a dry box ). Give a maker a 3D printer and every problem is solved by 3D printing.

Buried nuts and hanging holes

HydraRaptor

I needed to make some M4 nuts that could be finger tightened but I didn''t have room for a standard wing-nut, so I decided to embed nuts in a printed plastic knob. I knocked up a simple design in OpenScad :- M4 nuts are nominally 3.2mm thick.

If I hadn't had those I would have printed some custom plastic ones as I doubt 6mm x 1/4" spacers exist and 6 BA spacers are hard to find in the UK now. It could then be housed in a cheap plastic case.

Rollerstruder: a filament feeder / driver / extruder

Tridimake

And I learnt a lot of openscad and industrial design by the way. But this is another story, I will not talk about the hot end here: my goal is just to drive a plastic filament forward and backwards reliably. Also I did not want to use kilograms of plastic each time.

Mendel90 updates

HydraRaptor

To fix that I reversed all the bolts and put nut traps in the plastic parts. The design still supports the MDF and acrylic variants with screws, but I only sell the plastic parts for these. A couple of plastic brackets hold the ATX PSU in place.

Mendel90 design improvements

HydraRaptor

Another advantage is with a constant flow rate the plug of plastic that forms at the hot end transition zone will be a constant length. This implies there is less plastic in the barrel, so an excess must have been extruded while the plug was shortening.

Peel-able support?

HydraRaptor

I made the support in OpenScad by subtracting it from a cylinder. The difference may be the plastic. One of the few advantages commercial FFF machines have over Reprap at the moment is that breakaway support works much better.

Will it burn

HydraRaptor

In comparison a 40W CO 2 laser with a round spot of say 0.25mm would give a power density of 815 W/mm 2 , so I expected to be able to cut through wood and plastic a few mm thick with it. In order to be able to add new parts to it I decided to re-model it in 3D in OpenSCAD.

The latter only generates lots of strings and bits of plastic, but they are well contained in the bottom of semi-enclosed printers like the Ultimaker Original (the second version homes to the bottom, which is annoying in this regard imho!).
