• Turntable: The most basic and lowest cost 3D scanning systems use laser point or line projection onto an object positioned and rotated on a turntable. Prices range from a few hundred dollars up to low thousands. As a handheld solution, Fuel3D holds a significant flexibility advantage over these systems, as they are fixed position and the object being scanned is limited by turntable size.
• Sweeping laser line: To enable scanning of larger objects, scanners are available that project a laser line, which sweeps across a stationary subject. With a few exceptions, prices for these technologies are typically in the $20,000 – $50,000 range. Fuel3D has a very strong price advantage over all these systems, with the added benefit of handheld flexibility and color capture.
• Hand-held: 3D scanning systems have been developed to enable maximum scan flexibility for working around objects of almost any shape and size. Prices of hand-held solutions are now as low as $15,000 – $30,000. In addition to Fuel3D being much less expensive, we are not aware of any of these handheld systems that collect color data in addition to 3D geometry.
• Microsoft Kinect: Some low-cost handheld scanning solutions are being developed using the Microsoft Kinect platform. These systems are typically quite low-resolution resolution, so while they are good for capturing environments, they do not have the data precision or resolution for detailed object capture like Fuel3D.

Anna Kaziunas France met with SoftKinetic's Chief Marketing Officer Eric Krzeslo at their suite in the LVH to ask him about their new partnership with MakerBot to enhance their 3D camera technology for 3D scanning that was announced Monday at CES 2014. SoftKinetic is provides 3D vision and and gesture recognition technologies for the consumer electronics, automotive and industrial markets; who license their intellectual property.

Patented DepthSense® 3D Imaging time-of-flight CMOS sensor is smart enough to understand the most subtle of everyday human gestures and the shape, size and behavior of objects. It measures how long it takes for infrared light to make the trip from the camera and back – the time-of-flight – and gives the 3D DepthSense camera power to turn raw data into real time, 3D images, as well as greyscale confidence and depth map images.

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.
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.

The setup uses 39 Raspberry Pi + camera units. They all listen to a network broadcast to fully synchronized take 39 photos. The photos are then uploaded to a local SAN for further processing.
The 3d modeling is done using the free cloud service from Autodesk called Recap (recap.autodesk.com).

I always wanted to know, how much better a professional 3D scanner is, compared to my cool Carmine 1.09. You can use the 3D scanning Software Artec Studio with both entry-Level 3D Scanners like the Carmine 1.09, or Kinect and professional 3D Scanners like Artec Eva, or Artec Spider. Therefore I used this software to give you an impression what you can do with hobby scanners and what is possible with professional 3D scanners.
Please have a look at the amazing interactive 3D model from the Artec Eva scanner at: http://viewshape.com/shapes/7tckylse0l8

FABtotum is a multipurpose tool, the first Low Cost Desktop Personal Fabrication device that can operate a wide range of Computer controlled (CNC) manufacturing processes.
Print, Cut, Mill, Scan, Manipulate. Rinse and repeat!
A seamless interaction between the physical and the digital world.
While Current 3D printers are defined as Personal fabricators, there is so much more to personal fabrication than 3d printing alone! FABtotum allows anyone to explore the endless possibilities of a multipurpose fabrication device.
Thanks to a sturdy structure and unconventional tecnical solutions FABtotum is capable of subtractive machining without compromising 3d printing volumes or printing speeds.
Switching to subtractive mode is easy: just remove and tilt the double sided printing plane and expose the milling plane with built in fixtures to secure your workpiece.
Along with 3/4 Axis Subtractive Machining, Fabtotum is capable of 3-axis hybrid Additive / Subtractive manufacturing, meaning you can work in dual mode without loosing the position or having to move the workpiece.

• 3D milling on light materials (Balsa, Foam, light wood)

• PCB milling : make your own circuit boards!

• Engraving

• 2.5 D Profiling (cutting) on light materials (balsa,Foam,Light wood)

• CNC Pre-Drilling

• 4 Axis machining on light materials.

• 4 Axis Engraving 

Digital Aquisition:
FABtotum is capable of scanning solid objects thanks to a built in laser scanner (quick scan, medium quality) and one dimension (Z) touch probe digitalizer (hi-accuracy, very slow).
Using this feature you'll be able to unlock a whole lot of potential: scan and print duplicates of solid objects, create new objects with foams or modeling clay and scan them for further editing in a modeling software of choice, or print them in additive mode or cut/mill in subtractive mode.
Most 3d scanners cannot acquire small objects (such as a coin) and a physical digitalizer cannot acquire complex objects without at least 4 axis of freedom.
FABtotum can do both.
Scanning objects means you'll never run out of stuff to print, you'll be able to experiment with shapes or reverse-engineer objects around you, scanning and then duplicating a modified version!
