Poly Runes

torus-print-2

3D polys as PLA filament runes.

torus-print-1

Low poly exaggerated effect, silver, yellow and white.

torus-print-3

I peeled away some residue from the base of each object.

torus-print-4

Note to Self:

  • Some errors, but will know for again re: brims and raft scaffolding support.
  • The objects ‘inner landscape’, now forever hidden, but realised in the 3D printing process bestows upon the object whatever prophetic qualities it may inherit.
  • Throw the 3D poly runes, read from right to left.
  • More objects may be added to this Low-poly rune alphabet.

Ultimaker 2

Finally got to print some 3d objects on the Ultimaker 2+ and Ultimaker 2+ extended 3D printers.

3d-print-torus-1

We added two objects to each printers plate, one will print in silver and the other in yellow.

3d-print-torus-3

It was interesting to see how to check the .stl file in Cura software before transferring the info to the printer itself via a SG card.

3d-print-torus-6

I checked that the file was flat via the ‘lay flat’ feature, that both objects were yellow in colour in Cura, hence they were both inside the bounding box print area.

I checked the layers to see if the first frame would print to the build plate properly and manually tweaked the nossle if too far away.

3d-print-torus-4

I checked the scale size and also if the object needed support, so set to brim for some support, you use raft if it needs a lot scaffolding support.

3d-print-torus-5

I also tweaked the layer height to 0.15 so less layers to print and the shell thickness to 0.6 so as to make the shell slightly thinner.

Note to Self:

  • the 3D prints still it came in at 15 hours!
  • Interesting to see the objects ‘inner landscape’ as the layers gradually print, the interior will be hidden forever when printed.

3D Print

3d-print-1

A 3D print in progress on the Ultimaker 2 of a low-poly cone .stl file.

3d-print-2

The bounding box looks too high? will have to check on future prints.

Ok, so the point is a bit wobbly so just needs a bit of sanding, I think that happens with such fine prints.

3d-print-3

Note to Self:

  • I’m after a low-poly aesthetic, so probably should have exaggerated that a bit more.
  • The x2 escape holes are there anyway as planned, curious to see if it will be correctly hollow also.
  • Finished surface reminds me of a sea shell almost, much rougher than imagined, good to know for the future.
  • Maybe different filament gives a smoother effect?

Low Poly

Preparing a really basic Low Poly cone shape for 3D printing, originally created in Blender.

poly-1

Trying to keep the time/cost down by hollowing out the objects innards and adding escape holes in Meshmixer.

poly-2

Also looking at the bounding box and seeing if this is correct in Cura.

poly-3

Note to Self:

  • Not sure about the workflow in priming for 3D print, but after printing will hopefully see any errors and adjust my approach accordingly.
  • Once I see the best methodology, I can then print out my more adventurous mutant shapes.

Wrong’uns

wrong-un-3

When trying to do some 3D prints from object 3D scans, was confronted by a bewildering amount of vertices, edges and faces that the 3D printer can’t fathom.

wrong-un-1

Will generate instead a few quick mutated polygons that it can understand for print.

wrong-un-2

Note to Self:

  • On new basic polys: Hollow out the model and add escape holes to reduce print time/cost.
  • Scale down the bounding box.
