This product is the ‘Retractable Purge Mechanism’ hardware ONLY.
For those who have multiple printers or who wish to use it with a slicer other than SimplyColor3D.
This is a Pre-Order. Expected delivery is Sep/Oct 2019
The retractable purge mechanism hardware will be shipped out to purchasers in the order they purchased. The length of time it takes will depend on the number of purchasers.
The default way of purging the old color during transition between colors is to use a purge block. The main problems with purge blocks are that they must be printed on every layer even if there are no color changes, and they take up space on the print bed, and the final blocks are too large to be directly extruded into filament again. Our solution fixes all these problems.
We’ve designed a new retractable purge mechanism. It mounts to the side of your 3D printer and works with SimplyColor3D to reduce waste and decrease purge time. With our retractable purge mechanism, material is only purged when a color change happens which mean fewer purges and faster prints. The retractable arm means zero reduction of the build area and turns color transition purge into little blobs. The blobs can be extruded, like with the Filabot of Kickstarter fame, which means literally ZERO WASTE!

Our new retractable purge mechanism will free up the print area from purge blocks even if your 3D printer extruder cannot move past the edge of the print bed.

What is included?
This hardware ONLY option includes 3D printed parts and hardware. This kit contains everything you need to build a retractable purge mechanism for your 3D printer. Most printers will work with the purge mechanism but may also require some modification by the user to mount them. The kit is a straight bolt-on for the Prusa i3 MK3. We will work with our customers to support mounting the Retractable Purge Mechanism on each of their 3D Printers.
If you choose print and source the parts yourself then all of the 3D printable files and instructions for the purge mechanism will be emailed to you after purchase. You may choose to make the purge mechanism yourself but it will require some specific springs, screws, a modified thumb tack, a modified washer, aluminum tape, and kapton tape. All these things come already prepared in the kit so that only assembly is required.
What’s included in the kit:
-1 standard steel thumb tack (modified shortened)
-2 tension springs (.5mm wire gauge, 5mm ID, winding 8.8mm long, 20.5mm overall)
-200mm of 2mm wide Kapton tape
-60mm of Aluminum tape
-An M4 washer with notch cut out
-2pcs M3x10mm Flat head Allen screw
-2pcs M3x10mm Socket cap Allen screw
-1 tube of silicone grease (it’s the only grease that won’t harm plastic)
-3D printed parts: Bracket, cage, catcher, mount, action, connecting arm, wedge, flicker (unless specified at time of purchase, parts will be random color either cyan, magenta, yellow, black, white, or transparent)
