Marvin

3D-Print Hub?

Well I figured I would give 3dhubs a try.
The small Marvin statue took a while to print with any reasonable quality. I have to say printing smaller objects with reasonable quality is more difficult. However on my 3rd try I got a reasonable print with ABS.

The formula is as follows.

  • .2mm Layer height
  • 200C on the hot end.
  • 20mm/s movement (was not much different from 100mm/s 1-2min)
  • 0% infill
  • Active cooling of the part.

Lessons learned

ABS is really a weird material. If you print too fast or too thin on small parts it needs forced air cooling. quite the opposite of larger parts. The overhanging capabilities are quite decent with no real stringing.

Checklist for the future.

  • Design a clip on fan attachment
  • Insulate the heating block.
  • Increase effector precision.

Results?

The not so good

Afterthoughts?

I have to say that I really doubt I will get any sort of reasonable work done with 3dhubs. Simply put I do not think there is much market for it. I would be glad to be proven wrong. One thing I can say is that if I design something and print it myself and sell it I think the 3d printer can become sort of a micro factory. Most people today think these temperamental machines can become a money making scheme, however they better think twice, these machines are exactly like a CNC machine. It takes experience to operate one if you want to get the desired results. Experience is built by paying two fold in both money and time.

Good luck and happy printing. If you guys who seem to follow my blog like this blog, please drop me a line at engineerd3d@gmail.com I would love to hear your thoughts on 3d printing or my blog.
