3D Laser Scanning - have you done it?

[loopee]

Hey White-Light

Yeah, there are some print examples out there from various machines that in my opinion look shit and really don’t show what some of these early DIY generation devices can do

Here’s my first 0.1mm print next to a AAA battery, it has a few flaws (the start of the leg and the neck) and I forgot to change one setting that’s made the left side slightly rough but it came out really good for a first print



The Ultimaker printer is a bit cheaper and its currently faster and can do prints down to 0.04mm layers but you'll need to build it yourself where the Makerbot comes assembled with injection moulded parts (one of the seller to me) and apparently one of the Makerbot engineers has been able to do prints on a Replicator at 0.04 as well, it just take a bit of fiddling to get the layer high/material feed balanced to minimise the blobs (oh, and time)

You can pick up a Printrbot LC for just over $500 as a kit just don’t expect the 0.04mm resolution

Also material costs are somewhat similar to inkjet printer cartridges, for around $50 you get 1.0 to 1.5Kg roll of filament that seems to last. The model above weighs 3g so for a 1.5Kg spool it would equate to 500 prints

@Jem
For your projector, the David scanner system doesn’t seem to dependant on the projector resolution so it should be fine to use

A PL member I have much respect for has done this with a microvision picoprojector and was nice enough to share code. Be sure to Thank Her!

Hi Jem, not sure how you progressed on your 3d pursuits. I think
A pretty good balance between cost/time to build/results and learning curve. Is
3d scanning- NextEngine as Chad suggested
3d printing - Shapeways in the Netherlands.

The NextEngine is around $3000 from last memory+ a couple of bits of software. It's the cheapest of the turn key systems.
The David route gets pretty good results from what I hear but it would be pretty easy to speed more than $3000 dollars of your time to get it right.

I've been trying to justify buying one but wanted to hear more user reviews on it. As you will find there is almost no info online about it. I think there is a user group for it but you have to own one to join I think hence it seems a bit of a secret society.

Shapeways has a bunch of different plastics, silver, stainless steel. It's starts at about $1.40 per cubic centermeter.


I'd like to buy a Faro arm but they don't seem to be getting any cheaper.

how did your research go? Are you on the fence still like me?

The software to convert the STL files to parametric files you can extensively edit can cost a bit too.

What's the latest?

Good luck
Kit

Hi Jem,

I'm scanning with David Laserscanner - first with laserline, recent with one of the salvaged Casio-beamers with 'only-red'-mod and a SW-cam, what's much more accurate and faster too.

Here some infos in English: http://www.photonlexicon.com/forums/...-Diodes/page13

... and here some more in German: http://diy-community.de/showthread.p...ghlight=viktor

I'm active in the David-, RepRap- and German CNC-communities and building/using some DIY-apps around UV-3D-printing, powder-laser-sintering, milling and some combinations around laminating, sintering and novel techniques.

Some of this is under NDA but most is open DIY, so don't hesitate to ask ;-)

Hi Guys

I'm always full of good ideas and enthusiasm, unfortunately real life and earning a living always seem to spoil the fun . Sadly, I haven't progressed with this at all since my first posts on the subject, but it's great to hear that others are also interested.

I'm going to try and get back to my holography hobby before starting any new projects, that should occupy most of my spare time this winter.

Keep the information coming though as this thread will be a great reference for the future project.

Regards to all

Jem
