3D Printer, feedback, Gnome Monosoupape, H02

CAM love the 3D printed model and the innovative use of soda cans

We have determined, current engine weight will be approx 10lbs using 3D printed parts (as produced so far).

I shall discuss spool costs with Department to take this further.

They also thanked Kevin Bower for his support in cleaning model too (as I had acknowledged his help in my correspondence – participant acknowledgement being important).

Above : Incomplete 3D printer tests (MakerBot Replicator 2x)

Initial tests look promising, but we are getting incomplete prints – not sure why yet, although I suspect writing data to a DropBox enabled back-up folder may have corrupted original data.

Many thanks to Brenton Hilbig, a Junior Industrial Design student for helping me print the above – I was attending a competition at the time.

Further analysis / design modifications view-able here.

Assembled Measurement Cube

Key to both scaling and perspective matching, a ‘measurement cube’ is an essential component of the Image Based Lighting setup process.

Amazingly, they are very hard to find / purchase, so I decided to create my own.

In the past I have used a Gypsy 6 Motion Capture suit calibration cube  – which served the purpose, but also had following shortcomings:

  • Physical size was not ideal for IBL sets intended for larger asset renders
  • Color of cube made it had to see / work with
  • Bars very thin – making them hard to see.
  • It was part a system owned by my former employer in UK, so not available to me in USA.

Budget Alternative – Cardboard Board

In absence of above, I have used cardboard boxes, although this again has its limitations:

  • Not square
  • Cannot see through it
  • Harder to establish ‘perspective’ viewpoint

My solution comprises:

  • 8 X 3D printed corners – using a MakerBot 3D printer
  • 12 X 2 foot PVC tubes (courtesy of The Home Depot)

Cube Measurements (in Millimetres, as working in Metric inside Maya)

  • Across Centers = 630 mm
  • Tube Diameter = 21 mm
  • Sphere Diameter = 50.8 mm

End result – a fairly lightweight, highly visible asset – total cost about $20
