3d-Touch Dual-Head Printer [SOLD]

3D Touch Dual Head Printer for Sale in SF Bay

[The Printer is sold!]

As announced in a previous post, since I received my Form1 Printer I cannot really justify keeping my 3DTouch printer. It’s a shame as STL printers and FDM printers are complementary. I will miss the various colors and material available and the fact that the parts are ready to be used after print. No rinsing bath / UV curing needed like the Form1 🙂

What you will get is the full package with everything to print and a lot’s of filament (~22kg / ~$900 of filament). I would rather do a local sell (I’m south SF Bay) than prepare a shipment, it’s heavy! If you come to pick-up, I’ll give you a training session of an hour to learn how to prepare your model with Kisslicer, load the filament and print.

I’ll publish this on Craig’s list in a few days, so my blog readers have some early notice!

Content of the package

  • 3D-Touch Dual Heads printer lightly used (I’ve probably printed less than 4 kg of filament since April)
  • 18 New/unopened Bits From Bits 1Kg 3mm spools (various colors, PLA and ABS, see details under)
  • 7 used spools (with at least 4kg of plastic remaining of various colors)
  • All accessories: clamps, cutters, USB key to load models, Small diameter spools adapter…
  • Consumables: 2 inches blue tape roll, Acetone (only if pickup, I’m not sending it)
  • You can get the sturdy metal cabinet under for $180 (from Lowe’s store, only if pickup, I’m not sending it), it’s pretty handy to store everything.


PLA Spools Included

Note: on open spools the remaining weight are only evaluation, I’ve been conservative so you’ll get more filament! I kept my PLA spools on plastic bags after opening.

  • New Unopened 1kg / 3mm PLA spools from Bits From Bytes (protected in plastic with desiccant):1 Black, 3 Natural Clear, 2 White, 1 Red, 1 Blue
  • Open spools 3mm from Bits From Bytes:
    Black 200g remaining, Purple 800g remaining, Green 500g Remaining
  • Open spools 3mm Matter Hackers:
    Orange 300g remaining, Red 400g remaining


ABS Spools Included

  • New Unopened 1kg / 3mm ABS spools from Bits From Bytes : 2 Black, 3 White, 2 Green, 2 Blue, 1 Yellow
  • Open spools 3mm from Bits From Bytes:
    Yellow 900g remaining, Black 900g Remaining

For a friend wedding this was my last print, mustache for everyone and bow-tie for the groom! The 3D touch is sturdy and super reliable printer!

Impossible objects: a Symmetric Penrose triangle

For my last impossible object I built a Penrose triangle that was not symmetric (wit 2 strait sides and a twisted one). In this post I will try to build a symmetric object, using a few more techniques with Inventor.

  1. Getting the best visual result requires to tweak the geometry of the final object so my first step was to create 5 user parameters that will be used to build the triangle.  I then proceed to build a sketch of one corner of the triangle. Only the left side was drawn (with 2 orthogonal constraints in red). The right side is only a symmetry relative to the Y axis.penroseSymetric_step1
  2. The second step is to extrude the profile on both side by thickness/2, then use the move body tool to rotate the result by “angleRotation” through the Y axis.penroseSymetric_step2
  3. Then use the circular pattern to create 3 copies of the corner. I had to use the “pattern a solid” option otherwise the default “pattern a feature” was copying the corner without the step 2 rotation.
  4. Create a loft can be created between the two side faces of the top and left corner, then this loft can be “circular patterned” to complete the triangle structure.
  5. The result needs to be smoothed on the junctions to make it less obvious. Select the 24 edges around with a 10mm radius fillet to finish the triangle.penroseSymetric_step5

The final shape result is more pleasing than my first attempt to build a penrose triangle. More parameters could help the getting a better final shape, but would increase the instruction complexity so I’ve chosen to keep it simple.


The STL file is available on Thingiverse here, the Inventor part file is here.
