faBrickation a new approach to rapid prototyping of functional objects, such as the body of a head-mounted display. The key idea is to save 3D printing time by automatically substituting sub-volumes with standard building blocks — in our case Lego bricks.
When making the body for a head-mounted display, for example, getting the optical path right is paramount. Users thus mark the lens mounts as “high-resolution” to indicate that these should later be 3D printed. faBrickator then 3D prints these parts. It also generates instructions that show users how to create everything else from Lego bricks.
If users iterate on the design later, faBrickator offers even greater benefit as it allows re-printing only the elements that changed. We validated our system at the example of three 3D models of functional objects. On average, our system fabricates objects 2.44 times faster than traditional 3D printing while requiring only 14 minutes of manual assembly.

A couple of months ago I was sourcing parts to build a Delta printer and while I was doing I realized that I would prefer to have a big horizontal print area instead of a vertical one, so the concept for RepRap Tuga was born.
This concept should respond to this points:
- Static motor arrangement
- Speed of movements (X and Y)
- Big horizontal build volume (rectangular 400x180mm)
The resulting printer dimensions are aprox. 830x500x500mm
- Bellow 500€ cost
Some Weak points:
- Large horizontal printer size (double of the print bed).
- No heatbed for the first version
- Possible x/y axis wobble
Future Design Goals:
- Arms mechanism untested in this arrangement.
- Small version (250x120mm print bed)
- Try Vslots
- Replace side acrylic panels with printed ones (maybe prints holds to a wall)
- Put both horizontal carriages using the same smooth rods.
After his studies in mechanical engineering at the Vienna University of Technology, Jan Torgersen started his phd work at the Insitute of Materials Science and Technology. Jan's field is Additive Manufacturing Technologies; the technology involved in 3D printing. He developed a new printer that is able to produce nano-scaled objects suitable for numerous applications in photonics, surface modifications and biomedical engineering. This printer is currently the fastest of its kind and brings the technology closer to industrial applications. How it works got illustrated recently by a video that went around the world, showing the construction of a racing car model in the scale of a human hair.
In the video, a race car with dimensions of 330x130x100µm3 is fabricated. The structure consists of 100 layers, each made of an average of 200 polymer lines. It is finished in 4 minutes and resembles the CAD file at a precision of ±1µm.
A Spanish company called Natural Machines has invented a way to print food using a 3D printer.The $1,400 printer, called 'Foodini', builds up layers of different ingredients, then pumps out the final product ready for cooking.The machine uses capsules of fresh, unprocessed ingredients and is intended to get more people preparing additive-free food in very little time.Al Jazeera's Sonia Gallego reports from Barcelona.

Rather than mechanical endstops the RappiDelta Jr. utilises slotted optical sensors which prove more repeatable homing and ultimately better prints. One of my stretch goals is to be able to offer auto bed leveling to further enhance the functionality and ease of use.This delta projects wants to deliver cheap simple printer, with few easily assembled printable frame parts.
The remainder of the mechanical parts can be assembled quickly and easily with a couple of hex keys.
Once assembled the printer can print on a 17cm diameter circle and up to 17cm tall. These dimensions have been chosen based on my experience of what is actually reasonable to print as well as being based on a similar size to other entry level printers. In future you can increase the build volume by using longer uprights, and if required longer delta arms. The basic model has no bed heater and as such is limited to printing PLA (this is actually my preferred plastic!) but other options are available to allow the printing of ABS and other plastics that need bed heating. There is also an option to have an SD Card reader and LCD control panel to allow printing without a PC, something that I have found invaluable when developing my prints as it allows on the fly adjustments.

| DeltaTrix print results |
The theoretical printing area is 280mm (11 inch) in diameter. As a square this works out as (almost) 200x200mm (8"x8"), which suits the used 'MK2A' heated bed. As it is also useful to be able to remove items, the gap between the uprights is just over 295mm. The maximum build height is around 280mm (11").
Main features:
- Linear delta robot layout provides a mechanically simple motion platform for moving the print head only, not the workpiece.
- Off the shelf RAMPS electronics allow for easy replacement in case things go wrong.
- Using a LCD display and SD memory card (supplied in our kits), the DeltaTrix 3D Printer can operate on it's own. It does not need to be attached to a computer.
- There are several (Open Source) options in terms of software. At the moment we are using Repetier on the PC, a modified version of Marlin as the firmware on the RAMPS electronics, and the standard Arduino IDE for tweaking the firmware.
- A heated bed with glass print surface, allows for PLA and ABS to be used as filament.
- In terms of filament, the DeltaTrix 3D Printer is designed to accept 1.75mm PLA and ABS on a variety of 1kg reels, as long as it is of good quality.
- Igus linear slides with pretension are used, providing a robust and durable bearing solution from a highly reputable manufacturer. The strengthening ribs on the uprights keep the rails straight and sturdy.
- The current design print head assembly uses a single Reprappro Hot End, with a nozzle size of 0.3 or 0.5mm. The assembly also has a fan and integrated duct for cooling the top of a print.
- Quick changeover print head assembly. Useful for swapping between two print head assemblies, eg. one for ABS and one for PLA. The prototypes use connection blocks, but the kit will have proper connectors. Please, note: the standard kit only contains parts for one off print head assembly.

Create it REAL, a Danish 3D printing technology provider is pleased to announce the first worldwide 3D printing real time processor. After 2 years of research and developments, our team have succeeded in producing a range of chips that are going to boost the 3D printer industry.
Speed is the key breakthrough - the 3D RTP v450 can reach up to 450mm/sec which is some three times faster than typical desktop printers on the market today. 3D printer manufacturers will be able to solve the speed issue - which is blocking market adoption - without changing current designs and mechanics.
The chips are initially targeting Fused Filament Fabrication printers, but are also ready to support SLA technology (Stereolithography) and will support SLS (Selective Laser Sintering) in a near future.
Create it REAL partners will appreciate the ease of integration in their current range of printers. Using only the 3D RTP chip (installed on a standard dim socket), or the full motherboard including all the controllers for the different printer parts, OEMs will be able to release new versions of their products quickly.
Finally, Create it REAL also offers an optional intuitive software to print 3D files, optimized to take advantage of all the features included in the 3DRTP chip. If needed, OEMs can get a complete tailor-made package to meet their exact needs and make sure they offer unique value to their customers.
“Our objective is to support all the 3D printer players, from small start-ups up to large OEMs, and to offer them easy to integrate, state-of-the-art technologies so they can spend their time and resources on their most important assets: their customers” says Jeremie Pierre Gay, Create it REAL’s CEO.
Key Features Summary
• Worldwide first 3D printing real time processor
• Boost 3D printers speed up to 450mm/sec
• 3 different versions to address the different market needs from desktop to high-end
• Improved print quality thanks to smoother X,Y,Z (simultaneous control)
• Integrated temperature control for optimum filament extrusion
• Supports 3 motors, up to 2 extruders, 1 heated bed, 2 fans and 6 limit switches (start/end positions)

The development kit will be available end-January 2014 for 3D printer manufacturers eager to integrate Create it REAL technologies into their products.
Today the Computer Vision and Geometry Lab of the Swiss Federal Institute of Technology (ETH Zurich, Switzerland) announced on December 3, 2013 recent research results turning a normal smartphone into a mobile 3D scanner. 3D scanning aims to capture the geometry of the 3D world, however most existing solutions require a complicated setup, are often hard to use and might not always work outdoors. The technology was demonstrated publicly for the first time today at the International Conference on Computer Vision in Sydney, Australia.
Instead of taking a normal photograph, a user simply moves the phone around the object of interest and after a few motions, a 3D model appears on the screen. As the user keeps moving, additional images are recorded automatically and used to extend the 3D model. As all calculations are performed directly on the phone, the user gets immediate feedback and can select additional viewpoints to cover missing parts of the 3D model. This is an important advantage compared to solutions that batch process all the images in the cloud at a later time.
The app also makes it possible to visualize the state of the 3D scan from different viewing angles, allowing the user to cover all the areas of the object he is interested in. Having a solution on a mobile phone enables the acquisition of 3D scans on-the-fly anywhere. Our approach works in a wide variety of settings, including low-light conditions such as inside a museum. A user can capture a 3D model of a museum piece and interactively study it at home later. After reviewing the model, a user might decide to upload his 3D data to a cloud service to further refine the results.
By using the inertial sensors of the phone, the scanning process can be made simple, intuitive and robust. After the 3D capture is started, the system automatically determines the correct moments to extract camera images based on the user motion.
Contrary to image-only 3D capture solutions the app is able to determine the absolute size of the scanned 3D object, as well as the vertical direction. Because of the complexity of the calculations needed to reconstruct hundreds of thousands of points, the graphics co-processor (GPU) of the phone is used to enable a faster reconstruction and increase interactivity for the user.
The technology also allows the 3D capture of faces, giving a third dimension to portraits, profile pictures or images of loved ones.Source:
Having a convenient way of getting 3D models of everyday objects, users will now be able to copy real-world objects by scanning a full 360 degree model of an object. The resulting 3D model can be used for visualization or augmented reality applications, or even be used for 3D printing, potentially at a remote location, effectively enabling the user to replicate an object.
The patent pending technology was developed exclusively by ETH Zurich and can run on a wide range of current smartphones.
