RoboGames Awards

RoboGames Awards (on)


We’ve been helping out RoboGames with getting the award designs ready for next weekend. We just got the final prototypes done and handed over for production and we’re loving how they turned out! The awesome official artwork by Doctor Popular (below) features prominently on the medals, lit by throwie-style LEDs hidden between layers of acrylic. You want one of these around your neck, don’t you?



The event runs Friday-Sunday, June 12-14 at Fort Mason in San Francisco. Get your tickets now!


We’ll be bringing CandyFab to show off and lots of kits and pretty LEDs for sale. We hope to see lots of you there next weekend!

The CandyFab 6000

CandyFabLogo-color

Today we are relaunching the CandyFab Project with a new logo and a new wiki site, wiki.candyfab.org.

But more importantly, we are unveiling this new machine, the CandyFab 6000:

CF6k

It’s a brand new CandyFab– still in beta. A clean break, designed from the ground up with almost no parts in common with the original, the CandyFab 4000. All new mechanics. All new electronics. All new software. Smaller but still big: the build volume is more than 10 liters, but it’s now small enough to fit on a desk top.

second

Here’s one of the first objects that we fabbed on the CandyFab 6000: a drilled sphere, about two inches in diameter and layer thickness of 1/15 inch. There’s plenty of room for improvement, and finally we have a machine that can be improved.

Window-2

The machine is designed so that it can be made from scratch– i.e., without dumpster diving for old HP pen plotters. Three axes of quadrature-encoded DC servo motor control. Timing belts and acme lead screws. Food-safe sugar containment. The body is made from laser-cut plywood with acrylic highlights and stainless steel hardware. (Steampunk-compliant brass thumbscrews where appropriate, too.)

Zuccherino

The new modular electronics control platform is called Zuccherino– that’s italian for “Sugar cube.” One Arduino-compatible circuit board per axis. (Our prototype above shows X,Y,Z, Heat, and Air axes, plus a master board.)

It’s an expandable system for all kinds of motion control projects, and we’ll be making kit versions of all of the Zuccherino boards later this summer.

We’ve also got new cross platform control software — called CandyFabulous underway, and it’s looking sweet.

Printing

And… oh can it fab sugar. In the photo here we’re partway through printing an hollow torus eight inches in diameter.

Where from here? Check out more details at CandyFab Project and wiki.candyfab.org.

The CandyFab 6000 is destined to be an open-source kit project. We will be releasing CandyFab kits later this year, and once we have a first stable release, complete plans will be made available online, both in terms of software and hardware.

Finally, you can see the CandyFab 6000 first hand– this weekend at Maker Faire! We’ll be showing it off at booth #293, in the Expo Hall.

Evil Mad Scientist Laboratories and CandyFab at MakerFaire!

Maker Faire.Attention SF Bay Area folks: Evil Mad Scientist Laboratories and CandyFab are coming to Maker Faire! Space-time coordinates: San Mateo, CA, May 3-4, 2008.

We’ll be there in force with (amongst other things) a tabletop BristleBot Arena and great progress to show off on a lot of our upcoming projects: Next generation interactive LED coffee table panels, the debut of Peggy 2.0, and the brand new design for the CandyFab 5000, all of which we’ll be writing much more about this summer. Find us in the south hall, past the Tesla coils.

Great things are coming to Maker Faire, and you can come visit, get a sneak preview and chat.

We’ll sure hope to see you there. Advance tickets are on sale at a discount through Friday April 25.

CandyFab @ Dorkbot: 8/15/07 @ TechShop

symmetric view 2

On Wednesday, August 15 we’ll be giving a presentation about CandyFab at a meeting of Dorkbot SF, our local spinoff of
Dorkbot NYC.

Dorkbot chapters organize monthly talks and events for artists, scientists, and engineers centered around the theme of “the creative use of electricity.”

The meeting will be held at 7:30 PM at TechShop, a San Francisco Bay Area “open-access public workshop,” located just off of 101 in Menlo Park, where you can go use a wide range of tools and machines to make things. We’ll be bringing the CandyFab machine along, and– if everything goes right– demonstrating its use. So if you’re in the SF bay area, this is a great chance to come and take a close look at the CandyFab 4000, smell the caramel, and ask questions. Besides our talk and demo, there will be a couple of shorter presentations on other dorkbot-ish topics, and an introduction to TechShop. (Tours of Techshop will be available at the end of the meeting as well.)

Everyone is welcome to come to the meeting; there is a $5 suggested donation for the venue at the door.

[Link] See you there!

UPDATE: The event was great! (Read more here.)

Printing complex shapes: A sugar chain

Sugar Chain We made this chain of twelve giant links on the CandyFab 4000 to demonstrate the fabrication of a complex object, the sort that is difficult to make by conventional machining processes. You can see the 3D model and some build pictures for this monstrosity over at CandyFab.org.

This object also highlights the relatively large build envelope of the CandyFab– significantly larger than that of most other low end (i.e., under $50k) 3D fabrication systems.

PS for Chemistry geeks: insert joke about long-chain hydrocarbons here.

 

CandyFab.org : The CandyFab Project

CandyFab.org

Today we are spinning off one of our projects and launching a new web site: CandyFab.org. The new site is intended to help foster a community around the idea of accessible, low-cost, and open-source three-dimensional fabrication technologies.

The first major goal of The CandyFab Project is to completely re-engineer the CandyFab within the coming year. We plan to produce an open reference design in hardware and software for what will become the CandyFab 5000S– a low-cost solid freeform fabrication machine that can be built with commercial off-the-shelf parts.
If you’d like to participate in designing, constructing, or using machines like this, we’d love to hear from you. Hop on over to CandyFab.org.
