Create 3D Models From your Photographs with Autodesk 123D Catch

New iPad App 123D Catch Turns Pictures Into Printable 3-D Renders | Popular Science

Autodesk, one of the premier 3-D printing companies out there right now--they make AutoCAD, the pioneering software--has a new app out for iPad that aims to make 3-D printing easier. Just snap a bunch of pictures of the object you want to reproduce from different angles, and the app, cleverly named 123D Catch, creates a 3-D rendering automatically.



Turn Your Photos Into 3D Models With Autodesk 123D Catch For Apple iPad - Forbes


Complementing the desktop and newly released web versions, the 123D Catch app allows users to capture the world around them in 3D while on the go.  Imagine the potential for photos of vacation memories, family or other mementos brought to life in 3D. Captures made in 123D Catch can also be used as the foundation for further 3D modeling, 3D animation, or used to create a 3D printed object. Some cool real-world uses below.
[...]
Real world uses of Autodesk 123D Catch:
  • AfricanFossil.org is a fossil preservation project with Kenyan Paleontologist Louise Leakey. This cool project is in its infancy to document specimens in the National Museums of Kenya and in labs around the country.
  • Coral Reef protection – there’s a team documenting how coral reefs deteriorate using 123D Catch and then stitching together the pieces.
  • Cities and physical locations of all types can use reality capture tools with 3D drones to take photos and video to model an area or building or roadway.

Nanoscale 3D printing

Fast 3D printing with nanoscale precision | KurzweilAI

Printing three dimensional objects with very fine details using two-photon lithography can now be achieved orders of magnitude faster than similar devices in a breakthrough by Vienna University of Technology (TU Vienna) researchers.

The 3D printing process uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. The focal point of the laser beam is guided through the resin by movable mirrors and leaves behind a hardened line of solid polymer a few hundred nanometers wide.

Additive Manufacturing Technologies : Projects


Additive Manufacturing Technologies refers to manufacturing techniques which build up three-dimensional structures by sequentially adding material. Usually this is done by decomposing a part into thin layers and sequentially stacking up layer-by-layer. 

Additive Manufacturing Technologies : Two photon polymerization

Two-photon polymerisation (2PP) is a technique to fabricate three dimensional structures with resolutions down to 100nm (see St. Stephan’s cathedral and Tower Bridge). An fs-pulsed laser (usually emitting at 800nm) is focussed in the volume of a photopolymerisable formulation. Polymerisation only occurs in the focal point, where the intensity of the absorbed light is highest. This technique is the first AMT capable of fabricating true 3D structures without the necessity of layer-by-layer manufacturing.

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.

The Urbee Hybrid: the First 3-D Printed Car | Fast Company


Think hybrid cars are futuristic? How about a hybrid car that has literally been printed out? Stratasys and Kor Ecologic recently teamed to develop Urbee, the first car ever to have its entire body 3-D printed with additive manufacturing processes (by printing layers of material on top of each other until a finished product appears).


Huge 3D Printer Makes Buildings Out of Sand [VIDEO]

We’ve seen 3D printers before, but none quite this ambitious. Italian inventor Enrico Dini’s D-Shape is on a scale large enough to print entire buildings out of simple components: sand and an inorganic magnesium-base binding material.

WikiHouse: Open Source Home Building

WikiHouse – the open source house « Ponoko – Blog
http://blog.ponoko.com/2011/08/25/wikihouse-the-open-source-house
  • WikiHouse is a new project trying to make house construction open source. With WikiHouse anyone could download plans to CNC mill and assemble a house.
Printable homes coming soon, thanks to WikiHouse | Geek.com
http://www.geek.com/articles/geek-pick/printable-homes-coming-soon-thanks-to-wikihouse-20110817
  • Computerization has had a major impact on just about every aspect of manufacturing and fabrication. It’s also led to a democratization of the process, enabling enthusiastic DIYers with a bit of know-how (and a little extra cash in their bank accounts) to create some pretty amazing things with devices like 3D printers, desktop laser cutters, and programmable CNC machines.
  • It’s this last piece of equipment that WikiHouse wants to help you put to good use. The goal of WikiHouse is to allow people to freely download “open source structures” which can be opened and modified using Google Sketchup. The plans’ building components are designed to be milled from 18MM sheets of plywood, and the resulting pieces can be fitted together like a giant puzzle. They’re even labeled during fabrication, making it perhaps a bit more like building an Ikea desk (though that can be puzzling at times). In addition to marking pieces for easy assembly, the CNC will even cut a wooden mallet that can be used to ensure a tight fight between panels.

  • Download houses and components which are created and shared by an open community of designers from around the world. Individual parts can be combined or adapted using the free program Google Sketchup.
  • Click 'Make this House' from within Google Sketchup and WikiHouse generates a complete set of milling drawings from your model, which can be used by a CNC cutter to fabricate the house parts.
  • The parts are cut by a CNC mill using locally-sourced material. This is 18mm plywood, in the standard sheet size of 2440mm x 1220mm (8' x 4').
  • Set out the parts for each section onto the ground, assembling it like a double-layered jigsaw. You won't need any power tools.

EADS Airbike a 3D-Printed Nylon Bicycle

DailyTech - EADS ALM Process "Grows" Airbike Demonstrator

EADS can use the process to grow any part

EADS is known mostly for its work in the aerospace industry [...] has announced a new breakthrough in manufacturing with a demonstrator product called the Airbike.


The Airbike was constucted from a powder allowing complete and complex sections to be formed out of the powder as one piece. Things like the wheels, bearings, and axle were incorporated within the growing process and built at the same time. The product can also be built to rider specifications and needs no adjustment.

EADS calls the process Additive Layer Manufacturing or ALM. [...]

EADS Global Website EADS Global Website

The revolutionary manufacturing process is known as Additive Layer Manufacturing (or ALM) and it allows single products to be grown from a fine powder of metal (such as titanium, stainless steel or aluminium), nylon or carbon-reinforced plastics from a centre located next to Airbus’ site at Filton. Similar in concept to 3D printing, the bike design is perfected using computer-aided design and then constructed by using a powerful laser-sintering process which adds successive, thin layers of the chosen structural material until a solid, fully-formed bike emerges.




These parts were 'grown' from a nylon powder

Additive layer manufacturing for aerospace parts: News from ES Technology

The ability to produce components in a range of materials including hot-work steels, stainless steel, cobalt chromes and Inconel, plus titanium and aluminium alloys, presents the aerospace industry with large potential for direct part production using ALM.
Component designed by Material Solutions and manufactured on the Concept Laser M3 linear laser ALM system.

ALM has already been used to produce small and medium-sized aerospace components, and having realised the potential of the process, aerospace manufacturers are seeking to produce larger, more complex parts.

3D Bioprinting of Human Skin and Body Parts

Collected from: YouTube - Bioprinting

Like an inkjet printer, biological materials can be printed at home - SmartPlanet

[...]
Vladimir Mironov envisions a day when doctors might be able to print out new skin for a burn victim or print out a new organ for patients awaiting a kidney transplant. Mironov of the Medical University of South Carolina said he made the printer run on an open-source platform called Fab@Home. It could potentially print biological materials for surgical implants or print out robotic parts for cosmetic testing so animals don’t need to be used.

The printed material can’t really be implanted in humans yet, Mironov said, adding that more animal tests are needed. But imagine if you could take cells from a donor, culture them and put them into an ink and basically grow a new organ. This would avoid rejection issues associated with transplants and eliminate the need for a synthetic implant.

At the press conference, the device printed a silicon model of a human ear cartilage. It took about 20 minutes to print out an object shaped like an ear.
The object can be printed layer-by-layer. Once it is incubated, it can be implanted.

BBC News - 'Printing out' new ears and skin


Hod Lipson: 'People have been trying to expand the range of materials that can be fabricated using a 3D printer'
 
The next step in the 3D printing revolution may be body parts including cartilage, bone and even skin.

Three-dimensional printing is a technique for making solid objects with devices not unlike a computer printer, building up line by line, and then vertically layer by layer.

While the approach works with polymers and plastics, the raw ingredients of 3D printing have been recently branching out significantly.

The printers have been co-opted even to make foods, and do-it-yourself biology experiments dubbed "garage biotech" - and has most recently been employed to repair a casting of Rodin's sculpture The Thinker that was damaged in a botched robbery.
