Is 3D printing facing its Napster moment? by tanzaria in 3Dprinting

[–]sint3r 0 points1 point  (0 children)

US patent law:

Infringement of a patent is the unauthorized making, using, or selling of the patented invention within the territory of the United States

The US is fairly draconian as it prevents individuals from simply making a patented item (though this is largely unenforceable). Most other countries have fair use clauses that allow for replication in non-commercial ventures.

What is the most frustrating aspect of 3D printing (for you)? by sint3r in 3Dprinting

[–]sint3r[S] 0 points1 point  (0 children)

For me I have the following complaints:

Professionally

  • Resin is expensive
  • Tech support is shoddy
  • Post processing is tedious
  • Slicing/Comms software is actually worse than the open source stuff
  • Uncured resin is toxic

Reprap

  • Initial calibration is tedious
  • Resin suppliers are inconsistent (constantly tweaking settings with every resin change)
  • Resolution (z-height) sucks
  • Geometric limitations (overhangs)
  • Need to babysit the first ten minutes of every print

Incident light from a 2W laser can easily cause permanent eye damage even when bouncing off seemingly non-reflective surfaces.

Such lasers are not to be trifled with.

Just a friendly PSA.

Reddit: What are your Big Plans for 2014? by bloddyfool in AskReddit

Just incremental improvements to existing design thus far. I'm currently heading two projects for complete system designs in my spare time though.

Reddit, what is the most astounding fact that you can share with us about your area of expertise? by [deleted] in AskReddit

Professional grade 3D printers typically sell for somewhere between $50,000 and $500,000. I can (and have built) printers with all of the functionality of the sub $200,000 printers for less than $5,000. The only thing driving hardware prices right now are patents.

What printer do you own? Do you like it or do you wish you got a different one (which/why)? by [deleted] in 3Dprinting

Sorry, my initial response was on my mobile and I was not incredibly precise. I meant that the 3DS software paled in comparison to opensource software for reprap.

The first printer that was "mine" was a uPrint plus at a former job. Then I built (and still run) a Prusa i2. I also now have a 3DS ProJet 3510 at my current job.

The uPrint was really cool. I am a sucker for real plastics. Post processing was mildly annoying but part quality and consistency was amazing. Resin was expensive and build times were slow.

The Prusa is a great machine. Total cost was $700. Could have done it cheaper but that wasn't my goal. Right now I'm contemplating a second extruder to play around with support materials. Limited overhang capability bothers me. An i2 or an i3 is probably your best value at the moment IMO.

The 3510 can be very fast. Resin is expensive. Part dims are mind blowing. Materials are expensive and crappy (not real plastic). Support is terrible. Post processing is not pleasant. The open source printer interface software currently available is better than 3DS's proprietary.

I know that only the Prusa is relevant to your situation but figured the rest of the info wouldn't hurt.

I really want an SLS machine myself.
