Mini Metal Maker LEARNING page is now online on the Mini Metal Maker home page. View episode #1 and learn how to turn a hand-drawn image into a 3D printed metal object. The learning page includes an instructional video and accompanying materials such as links and file downloads for activites shown in the video. 

 

 

Printing human teeth

This is a short video featuring an experiment we did to see if is is possible to print human teeth from a digital file with the Mini Metal Maker. It is a crude first attempt, but we found that the detail and repeatability is quite compelling for this application.

 

Getting your machines up and running

February 28, 2015

It has been quite a month. First of all, I am pleased to finally announce that all but two lingering machines have been shipped to,and received by, their recipients. (If you haven't received your Mini Metal Maker and you were expecting it, please confirm your address with me. I don't want to ship to an empty building in Bolivia!) 

Preparations to ship machines: Please confirm your address :-)

January 2015

Hello supporters of the Mini Metal Maker project! We are just 2 weeks away from shipping out our full MMM production prototypes. If you are expecting to receive the full machine (and you know who you are) please write to me with your full name and address. I think some of you may have moved during the past 13 months, and I'd hate to ship to the wrong address. Please confirm your address in a message here with "Confirming Address" in the subject line. Thank you again and I will be in touch! -David

First orders placed with fabricators

September 2014

We have ordered the first round of five official Mini Metal Maker pro machines from the fabricator. They'll be the first five of the 30 full machines that we will be shipping out to you, our supporters. Once we make the last little adjustments (no doubt, to holes that don't quite line up, etc. ) we'll order the remaining 25.

You can have it in any color, as long as it is fire-engine red.  >:-)

Mini Metal Maker - DIY Instructions Released

August 2014

MMM-DIY pre-release

September has gone and so I have decided to release the DIY plans for the Mini Metal Maker in their current ALMOST-FINISHED state. I will have some additions and amendments, but the current release includes a set of 3d print files as well as a parts list and assembly layout.

Also, we do not yet have a release of the software. I will include a summary of a workable open-source toolchain and settings to use in my next update.

MMM Production Prototype & MMM-DIY

August 2014

MMM DIY Version & Production Prototype Version

What an interesting full month this has been in terms of the R&D and finalizing of the designs for the Mini Metal Maker. September is the month for getting all the DIY plans and the printed parts kits out to contributors. Of note to me has been the process of designing for DIY (do it yourself) vs the process of creating a production prototype.

Any color (as long as it's awesome red!)

3D Scan to 3D Bronze

May 2014

We produced a proof-of-concept print that involved a 3D scan, some digital manipulation, a print with bronze clay, some clay clean-up, kiln firing, and a final polish. I think you will find the results quite compelling.

I made a scan of Lindsay with a Cube Sense 3D scanner:

 

Layering Limit Solved: thicker clay, stronger motor.

Layering Limit Solved!

As part of our R&D involving extruded metal clay, we have been looking for ways to make printed structures as tall as possible without clay deformation or slumping. Our first approaches involved relatively soft clay and the use of a fan and allowing drying time on a layer-by-layer basis. This practically limited our layering to around 15-20 layers. 

Prize Prints in Progress

May 2014

 

For those of you who are expecting to receive 3d metal prints as your prize, the prints are nearly complete! The first round of prize prints are the keychains pictured above. The second round will be custom-printed objects of your choice. Please stay tuned if you are in the second group: I will be in contact soon.-David

T-Shirts on their way!

February 2014

The t-shirts to those of you in that prize category are on their way very soon. It was a wonderful opportunity to do some pen-and ink line art.  So there you go: hand drawn by the inventor himself! :-D  The last are being screen printed today here in Pueblo at Screened Effects.  I think they do a pretty darn good job. 

We did it! - Indiegogo Campaign Successful!

December 27, 2013Our Indiegogo Campaign was more than a success! With your enthusiastic support, we raised over $34,000USD, with our origial goal set at just $10,000.  Many thanks to those of you who have made this possible. Please stay tuned to updates, as our activities will now be transitioning into R&D mode and to getting all of the prizes out.We are elated and relieved, and I feel like I could sleep for a full two days. Thank you again, David Hartkop & the Mini Metal Maker Project  :-)
