Arcology Now - 3D printing geodesic buildings

When Brian Kordesal contacted me over facebook in April to present his idea, I was not even sure it was 3D printing at first, but I was quickly convinced. Idea is ingenious and simple. Arcology Now buildings are already being constructed and used as opposed to 3D building technologies which are just "around corner". It is also human assisted 3D printing technology, where human operator is needed to assemble finalised components.
Since it is based on geodesic principles, it could be very scalable and produce some amazing structures.

From Arcology website:
Our first product is our Universal Constructor. It's a house printer. We design structures as simple surfaces in any 3D editor (Blender3D, Maya, 3DS Max....). Then our software compiles a structure to match the 3D surface our designer created.
The resulting structure is cut out using a CNC plasma tube cutter and a press to flatten the ends of the tubes. The software writes detailed instructions on how to bolt the whole structure together. A team of builders can frame a two story house in a day.
After the frame is up we shrink wrap it with industrial shrink wrap. We then run all the utilities on the outside of the shrinkwrap. We spray on closed cell polyurethane foam. This is a rigid insulating foam layer about six inches thick. We then apply stucco to the exterior shell. This seals it from the elements. Instant house in any shape!
The software already fits standard sized windows and door openings... it will actually make any sized/shaped opening you want. Our goal is to have it also designing all the interior walls and flooring soon. Imagine a bamboo plywood floor with a laser etch mural that covers your entire floor, then encased in clear epoxy.
That's our style. We use low cost materials, advanced software and robotics to make amazing, livable works of art... at affordable prices! It's Moore's law meets construction costs.

UConduit h-bot 3D printer

Yet another cool h-bot made from steel electric conduit.

From project web page:
What is the UConduit? 
The UConduit 3D printer is an h-bot 3D printer, with a frame built from electrical conduit (steel conduit that you can find at the hardware store). It was designed by SSD member Lee Miller and is open source hardware via the Creative Commons Share-Alike license. It is hosted on github at All printed parts are designed using OpenSCAD (which is an open source CAD environment) so that parts can be freely compiled and modified.

Why electrical conduit?

There are many options for framing. Most higher-end 3D printers these days are using aluminum t-slotted extrusion or specialty laser cut parts. While I think these options are achieving excellent results, I wanted to build a printer that also had a solid frame, but went back to the hardware store mentality of the earlier Mendel and Prusa printers. Conduit is extremely inexpensive ($3.50/5ft) and plenty stiff for a printer. It created some extra challenges in design work, but has an additional payoff.

The printer is held together using o-rings and compression flanges. Each end has two rubber o-rings. There is a “hard clamp” and a “soft clamp”. The hard clamped o-ring creates a pivot point and firmly holds the conduit in place. By adding a second “soft clamped” o-ring on each end, vibrations are very effectively damped. As a result, the printer is not only fast, but also super quiet! As a physicist, I’ve used this type of connection to create vacuum-tight seals on tube furnaces, which is where I first got the idea. Additionally, wiring can be neatly routed from the top to the bottom of the printer (using the conduit for its intended purpose!).

What is an h-bot?

Think etch-a-sketch! I’ve never deconstructed an etch-a-sketch, but I’d guess that it probably works in a similar way. Two motors are connected to a single belt, which is wrapped in an H shape. If you turn one motor and hold the other fixed, the print head moves at 45-degrees. Combinations of the two motors turning the same way or in opposite directions gives movements in the x and y directions. An advantage to this geometry is that all of the motors in the UConduit remain fixed. Because motors are the heaviest objects in a printer, the inertial forces are significantly reduced by keeping them stationary. I worked with SSD member Free Beachler to modify the popular open source 3D printer firmware “marlin” in order to accommodate the h-bot geometry. I’m very pleased with the results so far, but 3D printing is very competitive in the maker world right now, so you be the judge!

Designing and printing objects with enclosed magnets

MstrJames gives great tutorial on how he designed and printed door handle with enclosed magnets. Key thing is to pause printing and insert magnets in enclosures and then continue printing over them.

BENDLAY - new clear and bendable 3d printing filament

Kai Parthy is at it again, after Laywoo -3d and Laybrick filament here is BENDLAY! Clear, resilient and food safe.

From video description:

what to print with?
• straps and belts
• thin wall bottles
• light-transmitting objects
• bathing shoes or sandales

• Outstanding is the opacity, near to plexi-glass.
• Bendlay is very nice to print between 215° to 240°C,
• 240°C is dedicated for best layer adhesion at fast printing speeds
• thermal stability similar to PLA (65 - 70°C)
• Bendlay is an modified Butadien and not made by nature, but may be used for household and food products
• the water absorption is only 30% of the ABS
• while bending, the clear color will not change into white (white fracture) as ABS or PLA do
• good adhesion to ABS and PLA
• soluble in break cleaner, acetone will make Bendlay crumbly

32,80 EUR for 0,75 kg of 3mm, available at:

The Turbo Entabulator

3d printed mechanical computer. Looks cool and it is powered by hand. No practical application :-)

From video description:

This is a (nearly entirely) 3D-printed, entirely mechanical computer. The machine has three single-digit, base-10 registers for memory, and is running a 4-instruction program that computes the fibonacci sequence. In the video, it starts out with the registers reading '1, 1, 0', and computes the fibonacci sequence up to '8' before overflowing. For higher resolution photos and a write-up, see:

Stratasys buying Makerbot!?

Is this true? Tectonic shift in DIY 3d printing market...

the Brooklyn-based 3D printing company, is in talks with Minneapolis/Israel-based Stratasys regarding a possible acquisition by the latter, according to a source close to the matter. While Makerbot founder and CEO Bre Pettis refused to comment on speculation, and in fact told reporters “We’re not going anywhere” at a factory opening on Friday, persistent rumors of a sale or new funding have followed the company this year.
Stratasys makes high-end, professional-grade 3D printers for industrial applications. For example, the Liberator 3D-printed pistol was built on a Stratasys machine. Stratasys does not yet have an entry-level model for average users, a niche in which Makerbot has generated $50 million in revenue this year.

Form 1 3D Printer: The First of many. from Robert Vignone on Vimeo.
This is a time-lapse video I made to document the process of printing out my Benedict Cumberbatch model. I will have a follow up video showing the final cast in (hopefully bronze!) or at the very least matte grey which will show off the details much much better. The print took about 12 hours from start to finish in the printer.

I sculpted the model in Mudbox, Prepped the model for 3d print in ZBrush and Meshlab and printed through the PreForm software. It was a good learning experience, overall a big success considering it is the first 3D print I have ever done myself.

Thanks for watching, feel free to follow me here, on Twitter, or check out my site for more updates (lots of good stuff coming real soon)
