RevoMaker Multi-directional 3D Printing with Embedded Electronics

RevoMaker uses hacked standard 3-axis FDM 3d printer and a laser cut cube core to print on its six sides. Cube core element can contain electronic components so ypu can make compex geometry objects with active components.

From project description:

We present “RevoMaker”, a self-contained 3D printer that creates direct out-of-the-printer functional prototypes, using less build material and with substantially less reliance on support structures.
By modifying a standard low-cost FDM printer with a revolving cuboidal platform and printing partitioned geometries around cuboidal facets, we achieve a multidirectional additive prototyping process to reduce the print and support material use. Our optimization framework considers various orientations and sizes for the cuboidal base.
The mechanical, electronic, and sensory components are preassembled on the flattened laser-cut facets and enclosed inside the cuboid when closed. We demonstrate RevoMaker directly printing a variety of customized and fully-functional product prototypes, such as computer mice and toys, thus illustrating the new affordances of 3D printing for functional product design.

How to Make a Concrete 3D Printer

Muhleman developed a concrete powder bed 3d printer that uses hacked Shapeoko CNC router mechanism.

It uses sand and cement mixture and a liquid soil hardener called polypavement as binding agent. Powder bed is loaded manually :-) but a mechanism could be developed in the futre.
Printed objects are rough but the concept is interesting for artistic purposes and concrete furniture where you can get more complex organic forms.

Full construction guide with plans and operational instructions can be found at:

Here is a video of it in action:

Aurora Flight Sciences 3D Printed UAV with Jet Power

Project description:
Aurora Flight Sciences, a Virginia-based manufacturer specializing in advanced UAV systems, is pushing the envelope of UAV design by teaming up with Stratasys to create the world’s first jet-powered, 3D printed aircraft.
Using 80% 3D printed parts, the UAV is composed of Stratasys’ ULTEM™ 9085 lightweight material to achieve flight speeds of over 150 Mph. The high-speed system boasts an impressive 9 ft wingspan and weighs in at only 33 lbs.

Repairing fridge light switch with 3d printing

Nicholas Durdan, well known for using his 3d printer to repair broken parts on his Ford Focus made a DIY 3d printed replacement for a broken fridge light switch.

It is a perfect example of how home digital fabrication is changing the nature of replacement part economics.

Identify the broken part...

... design the replacement piece ...

3d print and replace!

How are large city and terrain map models 3d printed and assembled?

Here are two projects that demonstrate how you can make very large models of cities or terrain by connecting smaller pieces in larger frame.

3D Printed Model of San Francisco

Video description:

Behind the scenes 3D printed model of San Francisco:
Connex 500 printed 3d model of a portion of San Francisco. The model was created to aid real-estate developer Tishman Speyer in telling the story of urban development in the rapidly changing SOMA neighborhood. It can help with urban planning and building construction decisions that are better understood with the kind of physicality that only a real-world 3D replica offers compared to digital images or digital models.

3D Printed terrain map of Canton Bern in Switzerland printed this terrain map of Canton Bern in Switzerland, made in scale 1:25'000 out of 340 tiles. 4.9 x 4.5 x 0.17 m. ca. 75kg PLA used, 12'000h total print time on 7 Ultimaker printers during 7 months.
