Video of new 3d printed cruiser skateboard

From video description:
Tas Oszkay, Mo Harmon, and Jac Currie are graduate students at UCLA's school of Architecture and Urban Design who re-imagined skateboard product design using ( Solid Concepts' 3D Printing to manufacture an incredible board in one unit. Their board is an involved aesthetic dialogue between form and function. The design reveals heavy influences from the team's organic inspiration, Radiolaria. From a machining perspective, the complex mineral shell of radiolarians is nothing short of a nightmare. The patterns of the organism from under a microscope weave into each other, looking roughly similar to a dried up piece of sea reef. The team took the basic design of the silica skeletons unique to radiolarians and further complicated it through layering using CAD software.
Their board is self identified as a cruiser, meant for gracing the beach front or getting about campus. They think in the future they might look into trick boards; 3d Printing is a technology capable of being extremely light, and that would factor well into such a venture. But for now, they're experimenting with the more relaxed board.
Here is the post about first 3d printed skateboard project:

3D Printer in Minecraft

Virtual 3d printers made inside popular indie Minecraft game that use in-game physics and building elements. They took a lot of time to develop and build. Kudos to you builders!

Printupy 3d printer by 2PrintBeta

From the Printupy product page:

This 3D printer is the quintessence of the state-of-the-art technology - a professional looking desktop accessory:

  • Input: direktly via USB or independent from the PC with a SD-card
  • Price: 1200 euro for single extruder version, 1500 euro for dual extruder version

Advantages of a timing belt driven Z-axis:
Most 3D printer systems use a lead screw or a threaded rod as drive for the Z-axis. Backlash and imbalance cause errors in X- and Y-direction when moving the Z-axis. These errors are visible as vertical pattern on the printed object.
When using two timing belts as attachment for the Z-axis these errors can cleverly be avoided. Consequently the Z-axis is nearly error free, thus the layers of a printed object lie perfectly on top of each other.

There will be single and dual extruder versions, currently they are on pre-order: First delivery in February 2014.

Video of the early beta prototype:

Here is a new video of Printupy production model in action:

Solidator large volume DLP 3d printer

Looks like the Form 1 is getting some (larger) DLP competition.

From Solidator Kickstarter page:

Size matters.
Solidator features a huge build area that is 3-4 times larger than that of most other commercial stereolithography printers and even a lot higher than those of the most FDM printers. No longer will you be limited to small prints - the 588cm² print area yields objects that are truly massive by comparison.

Speed sells.
Whether you're rapid prototyping or simply impatient by nature, speed is king. Using DLP-Stereolithography and specially formulated materials, Solidator hardens an entire 0.1 mm layer all at once, without the typical moving heads or lasers that do nothing except waste your precious time. This makes Solidator the fastest liquid plastic resin printer around, without sacrificing quality.
Resolution impresses.
Solidator can print features as small as 270 microns (0.0106 inches) and layer heights of 100 microns (0.0039 inches). This leads to impressive results. Just compare the object resolution with my fingerprint:

The Hardware

The patent-pending design is realized in laser-cut steel parts, precision-cut aluminum profiles, linear guides, motors, optics, electronics, acrylics, and a special liquid plastic resin container. All parts are sourced from the USA and Europe and will be assembled and tested here. The machine will be shipped preassembled to you with minimal final assembly required.
We've tried to take ease of use to a whole new level. Solidator supports Wireless LAN, Ethernet and USB keys so there is always a convenient way to get your 3D model onto the device no matter where you work. And with a built in 3.2” touch screen for user interaction, you can even print without a computer handy. As a light source we use a high power DLP projector that is calibrated and fully automated. There is no dangerous laser that requires you to wear safety glasses. The red protection cover helps to keep away sunlight from the liquid plastic and should be used whenever possible to extend the life of the material.
Technical Specifications
  • Build Volume: 280x210x200 mm (11.02"x 8,26"x7,87")
  • Z-Motor resolution: 10 microns (0.000393")
  • Typical layer height: 100 microns (0.00393")
  • Minimal layer height depends on the material used. 
  • The Z-Motor is able to go down to 10 microns layers. We will write an update on the actual value for each material. Expect this to be around 30 microns.
  • XY-resolution: 270 microns (0.01063")
  • Number of Voxels in Build Volume: More than 1.5 Billion Voxels
  • Speed: 10 seconds per 0.1 mm Layer
  • Footprint: 620x600x480 mm (24.4"x23.6"x18.7")
  • 3.2" Touch Screen supports standalone printing
  • Job transfer methods: Wireless LAN, Ethernet, USB
  • Software support: Windows XP/7/8, MAC OS X, Linux
The Software
The printer comes with Solidator Studio, our software solution for 3D rapid prototyping. You can open 3D models in “.STL”, “.OBJ” and “.3DS” format and place them into the scene to print. The software includes an industry leading GPU-accelerated slicer and automated support generation. Files can be transferred to the printer via WiFi, LAN or USB Stick. The software is tested on and available for Windows XP/7/8.x, Mac OSX and Linux Ubuntu.

The Materials
We have developed a special liquid plastic resin (similar to nail polish) with our resin providers. The prints in the pictures are printed with these resins that are specially designed for Solidator. Resin prices start at an industry leading $50 USD per liter (excluding shipping) and will be available from our partners. Compare that to some other stereolithographic printers that charge $150+/liter, and you'll see the advantage of Solidator.
The Solidator Resin we currently use is extremely hard, too. The hardness of the printed parts (at 0.1mm layer height) is 85D (shore hardness) - this is about the same value as PLA (about 85D) and more harder than ABS (about 75D) and certainly harder than POM (about 80D). The melting point of the printed parts is about 110°C (230 °F).

Is it legal? Is it copyright violation? Does it void guarantee? I don't have a clue ...


Update 5:

Da Vinci announced that hey will start to sell cheaper user replaceable ABS refill filament for their custom cartridges. It will be their filament and they will deliver it with a chip enabling the printer to recognize new spool. The refill will be sold in 25 - 27 USD range for 600g.
The company also announced that they will start to sell PLA filament also.

Daily 3d printing - custom baby mask for asthma medicine nebulizer

Louis Cordoba designed and 3d printed custom nebulizer mask for his asthmatic child.  Regular mask was too big for his baby boy so he made a smaller one with better fit so that child could be administered with correct dosage of medicine. It took 3 hours to print using 20 grams of PLA.
