World Maker Faire 2013: Innovative New 3D Printer Design

Nicholas Seward at ConceptForge gave us a demonstration of "WALLY", an innovative new 3D RepRap design at Maker Faire.

WALLY uses a SCARA/pantograph approach that totally eliminates linear rails, appears to be more compact, and is able to print parts for a next generation copy/clone that is 20% larger than itself. According to Seward the process can be repeated with each generation being as much as 20% larger than it's predecessor.

The part print quality was a bit rough, but Seward explained that the prototype WALLY on display had only been running for 3 days. He expects the print quality to match other 3D printer designs on the market after he has a few weeks for fine-tuning.

WALLY features a 3/8" water jet cut basalt bed with a laser cut registration grid; Anubis hotend equipped with a FEP Bowden tube (similar to Tantillus) that minimizes the print head mass resulting in smoother prints; linear motion drive utilizing 100lb test braided fishing line (another design approach similar to Tantillus); and is wall mountable.

The print envelope is 200 mm in diameter by 150 mm tall. The printer is designed to use 1.75mm PLA filament, though it could probably be modified for use with other filament sizes or types.

Seward estimates that WALLY will cost USD$450 for a "print your own" version and plans to offer a full kit priced around USD$600.

World Maker Faire 2013: 3D Printed “Pot Head”

It's surprising how rapidly the capability and capacity of affordable 3D printers has increased.

There were several exhibitors at Maker Faire in NYC last week showing off printers with print envelopes large enough to print really big objects. Of course the print times can be extremely long, and there is also the issue of warping with large parts. Still, the results were very impressive and encouraging.

Using 3D Printing for Practical Designs

IPhone Lens 3D printing

Design World has an online webinar scheduled for next Tuesday, December 4th, featuring Chong Pak of Olloclip explaining how they used 3D printing technology to design and manufacture their 3-in-one lens system for the iPhone camera. According to the webinar registration webpage:

"Olloclip has created the ultimate 3-in-one lens system for your iPhone that fits in your pocket and takes your picture taking ability to the next level. Product design in the most recent years has been impacted tremendously by 3D printing and Olloclip’s camera lenses are no different. Whether it’s wide angle, fish eye or a macro picture view, this development in camera phone technology has been made possible by Objet 3D Printing. Please join Chong Pak of Olloclip and Objet Geometries as they discuss product design within the iPhone era and how 3D printing can help engineers design, create and ultimately bring products to life faster.

Attend this webinar to learn about:
-Olloclip and their fast hitting iPhone accessory
-3D printing and the design process
-Objet’s multi-platform capabilities"

Hobby Lathe Produced by 3D Printing (Video)

Sublime (Brad) at Tantillus.org printed a fully functional hobby lathe using PLA plastic capable of cutting metal parts. Each of the parts necessary to build the lathe was small enough that they could be produced on an affordable 3D printer within the budget of most robot hobbyists.

The lathe design was the result of contributions from many people, though Sublime added his own touches/improvements. The surprising thing for me was that it is definitely possible to bootstrap from a low-cost 3D printer to create other tools that most robot hobbyists want for their home workshops.

I'll be posting more about Sublime's work and the creation of the Tantillus 3D printer in subsequent videos.

Makerbot User Group NYC Meetings Available via Ustream

makerbot user group

Just discovered that there's a regular Makerbot User Group meeting in New York City and the meetings are shared live via Ustream.

Archived videos of meetings are available online, though it looks like they just started adding content. Could be a treasure trove of information and inspiration as more meetings are added in the future. 

I won't embed the stream here because it tends to auto play in some browsers, but you can access it via the via link below.

Workhorse MakerBot 3D Printer At iheartengineering

iheartengineering found that the key to producing large parts without warping was to maintain a stable ambient thermal environment.

This was especially true because their offices are located in a converted brick warehouse building with concrete floors, lots of drafts, and inconsistent heating during the winter.

To deal with the unstable office temperatures, and to make sure that any objectionable vapors given off by the MakerBot were exhausted outside the building, they constructed a simple housing and venting system.

3D printer

As a part of the venting design they needed a part to mate between the housing and off the shelf ducting. So they did what any self-respecting engineering firm would do - they quickly designed the part they needed, using open source CAD software of course, and printed it out on the MakerBot.

The special housing allows them to run the 3D printer continuously for hours, and sometimes for days, on end. The stable temperatures result in consistent prints as well as allowing them to produce parts as large as the MakerBot workspace will allow.

Affordable 3d Printers Hit The Market…? (Video)

3d printer

Last week I visited the iheartengineering headquarters in Brooklyn and was surprised to find that they have managed to build a rapidly expanding business around the print-on-demand model and unique product designs. Besides their abundant creativity, the heart of their business is a first generation MakerBot 3D printer that manufactures parts as orders come in the door (or over the internet).

It's not unusual for them to keep the printer running for hours, and sometimes days, at a time when orders peak. They've developed some special techniques for producing large parts with some unique fill patterns that I will post more about later.

Most important, the work, and the business model, that iheartengineering is pioneering convinced me that all the buzz about 3D printing generating a rebirth of manufacturing and creativity in the U.S. is much more than just hype. It is a practical and achievable goal, one that may soon be a reality for a growing number of start-ups.

Endless Robot 3D Prints Full Scale Tables and Chairs from Recycled Waste (Video)

robot 3d printer

OK- all the buzz and furor about small 3D printing technology, like the Makerbot, is great, and it will be wonderful when all of us have the ability to create any necessary, or unnecessary, object at home, at will. But, what's at the other end of the scale - bigger, better, and even more ecological? How about a 3D printer robot that recycles waste of all types and uses it to print big stuff, like furniture? Wouldn't that be cool?
