3d printing

Beware: Your 3D printer might be trying to kill you

 

Well, here is some scientific support (see attached pdf) to why your 3D printer might try to at very least harm you!

The study only incides over particle emission, and not the chemical nature of the emitted particles and yet it can be scary enough. That, added with my reported symptons after going on a 3D (ABS) printing binge: persistant chest pains/disconfort should be enough to keep you on your toes.

 

So you better ventilate/filtrate if you're into this messy business.

Thinking about building a Wallace.

Hello,

I am thinking about building a Wallace Reprap.  Are there any others that have it?  Pros? Cons?

Thanks for any info!

 

Lathon, DUAL NOZZLE 3D Printer on Kickstarter

Hey everyone,

We are a startup called Lathon3D and are running a Kickstarter campaign for a new 3D printer. The LATHON has two nozzles that can print in two different materials and two different colors. Below are test parts with blue ABS and red Thermoplastic Elastomer:

The LATHON also has a massive 12"x9"x8" enclosed build area. The best way to explain it is to show what the LATHON made in a just 3 seperate pieces.

Pandora, the Makibox (by Kariloy)

Well, as many of you know I've been waiting for my own very 3D printer kit for quite a while (almost 16 months). But finally, this past Wednesday (Feb, 5th 2014) I finally got it. If you want to read more about it's arrival you can check it here.

And if you fancy really poor quality videos and you see the initial unboxing here.

RepRap - Issues trying to simulate a print

Okay, so this is my first forum post on LMR so bare with me please.

WHO WANTS TO PRINT MY 3D Printed Gifts? (Rephrased...)

Every year I make my future mother- and sister-in-law custom gifts (usually a horse and an owl, respectively.)  This year it occurred to me that I could create them digitally and have another LMRtian with a 3D printer print them for me, giving me a chance to spread a few bucks around.

Sketchy businesses -- my 3D parts modelling log...

Well, currently there's not a day that goes by without me reading someone talking about 3D printing, 3D printers and whatnot. Also, I've been reading of how easy SketchUp is to work with, so given my failure to make anything of Blender around almost 10 years ago... I decided to give SketchUp a try.

Note: Newer designs are at the top (for chronological reading start at the bottom of the post)

Project Reprap Rostock Rosblog (Hopefully not ROSFLOP!)

Thought I would start a blog documenting my rostock build. Hopefully this will help some other noobs work out the minutae of a project involving so many disciplines!

Rostock Build Blog.

 

For years there have been many great versions of DIY desktop manufacturing tools, and one of the most fun to build (and watch while it prints) is the Rostock 3D printer, which uses delta kinematics to equate its motion. 

Requesting Info from 3D Printer Gurus

Hello LMRarians,

I can't wait any longer, I have to commit to get a 3D Printer.  
I have seen all the Printer Guru's create their own versions from RepRap or purchase Makerbot or other systems and create amazing parts.

I was wondering if I could get a summarised list of Pros & Cons from experts who have created or used these marvelous devices. 

Hopefully, someday soon I'll be able to join the Richard Gear family !

Getting Started with 3D Printing

LMR is a great place to work together, learn and build. When you put cool new tools and tech in the hands of the community here, we can make awesome new things! When I first started wanting to build a 3D printer in 2009, there honestly wasn't much documentation out there to learn from  like today, and lots of my questions were left to the Great Google. Here is an attempt to at least collect some info for those starting on the 3D printing path...

FreeBOT (work in progress)

Project

FreeBOT - Is a Biped robot designed in Google Sketchup and printed out on a 3d print. My aim is to make it Free to everyone to print and improve. Since I can't afford a NAO.. this was the next best thing :-)

Design of 3D printed enclosure

We are currently working on the new version of our BeagleBoard-xM based robot. The main reason for redesign was the lack of wheel encoders which prevent us from developing more sophisticated navigation algorithms. That is why we decide to use Dagu Rover tracked chassis. However, not all our electronic could be fit in to the chassis, hence the need for additional enclosure on top of it.

This is an additive rapid prototyping machine that can print lots of its own parts, it replicates!
