3D Printing - Micron resolution

3D Printing - Micron resolution

Postby Richard-B » Tue May 07, 2013 1:24 pm

"NEVER say "never" !!!" Modeling technology marches ever onward:

This is the first 3D printer I've come across showing micron (that's 0.001 mm !!! ) resolution...
http://www.nanoscribe.de/en/applications/3d-micro-rapid-prototyping
less than an 1/8th of a prototype mm in TT-Scale! (0.120mm)

I'm sure the technology cost is high today...
but I would bet that this type of resolution will become available to modelers from a 3D printing service at sometime in the not-so-distant future.

Now we just need access to a "library" of royalty-free .stl files for various railroad components...
and the rivet-counters can graduate to a discussion of whether the prototype used "fine" or "coarse" threads.

In a few years there's going to be an explosion of models.

I hope so! Maybe then the other model railroaders won't think I'm nuts!
Me, personally, I'm waiting for the Replicator ala Star Trek. Instead of "Tea, Earl Grey, Hot" I'll be saying "EMD SDP45, Erie Lackawanna, TT Scale".

Personally I don’t think we will ever see much improvement in Shapeways (or any other company's) abilities, at least not any that would be usable for us.

In order to get better resolution they need to use a smaller nozzle for squirting down the layers of material. The smaller the nozzle the longer it takes to build up the model. Decreasing the size by half would multiply the process time by 4. I believe they would need to decrease the size to at least 1/4 in order to achieve significantly better results. That would amount to the process taking 44 times as long as it does now.

The Nano scale process Nanoscribe is using would probably take hours (or days) just to create something the size of a coupler.

I hope I'm wrong but that's the way I see it.

These 3D printers don't extrude or "squirt"...
Similar to the FormLabs unit... http://formlabs.com
the NanoScribe http://www.nanoscribe.de uses a laser to fuse a puddle of liquid material.

MUCH faster... and with better resolution.

Ah, didn't realize they were such different processes. That Formlabs machine looks like something to keep an eye on.

But what is the durability of the resin material. The shapeways cars I purchased came out of the package looking adequate but failed to stand up to what I would consider normal model railroad handling. The model has to look good a year from now too.

I'm wondering about the same thing. But, we won't know until someone has something in their hands. Also, we have to assume that as time goes on the materials will get better in various ways - hopefully durability will be one of them.

The Quickparts.com site says they give out samples, and they are only a few miles south of you. :whistle:
