The basic principles of design are being transformed by exciting new realities in materials and production methods that borrow principles from nano and bio technologies, but at a macro scale.

While the new generation of 3Dadditive printing technologies are currently limited by the few plastics and soft metal consumables that form the objects they create from CAD files, 4D is showing enormous promise.

Advances in the nano biotech world are being applied at a macro scale, using exciting new materials that can be programmed to change their form over time. I spent some time earlier this week with Carlos Olguin, who runs the Bio/Nano/Programmable Matter group at Autodesk, and spoke with Skylar Tibbits of MIT, and Shelly Linor and Daniel Dikovsky of Stratasys yesterday to find out more about the ways this nascent industry is taking shape and how they all work together.

The fourth dimension in 4D printing refers to materials that are able to change and mutate over time when exposed to water, temperature changes and/or air to self assemble. 4D object formats will soon have API's (Application Programming Interfaces) that enable designers to define the characteristics of the materials they are made from, which are then printed using sophisticated chemical calibrations to enable specific attributes and functionality.

Like the home brew computer movement in the 1970's that enabled DOS and early PC's, the new "4D" frontier today (Skylar Tibbits is the originator of the modern 4D concept) is an intriguing mix of participants. Autodesk, who are becoming central in the life sciences area, providing design tools for nano scale that originated from their ubiquitous architectural and mechanical design tools, now finds the micro world influencing the macro. Academia is at the forefront of exploring this emergent world in collaboration with Autodesk and others, with an aim of democratizing the space with standards and APIs that coders and designers can use.

Stratasys have been in business since 1989, and their maturity in 3D printers and 3D production systems for office-based rapid prototyping and direct digital manufacturing solutions are an important part of this new movement. They merged with Objet Geometries late last year and are central to the manufacturing process. Organovo make biological 3D printers: their "bioplotter" can shape living tissue using living cells, and will ultimately be able to "print" living organs — and they are now collaborating with Autodesk to create 3D design software. These companies are all individually interesting, but the blending of their disciplines makes for some truly fascinating innovations.

According to Carlos Olguin of Autodesk, the goal is to democratize the space to enable lay people without multiple PhD's in chemistry and life sciences to experiment. Stratasys' global education director Shelly Linor discussed with me the ASTM F2915 xml standard "Additive Manufacturing" file format (.amf ), which standardizes the attributes Autodesk and others need to design around. These file already describe the geometrical attributes of objects — now they are being used to define material consistencies and blends. Autodesk will soon launch "Project Cyborg", and you can download 123D, a movie phone 3D object scanner, today.

The synergies and collaborations between these companies and the Self Assembly labs at MIT, headed up by Skylar Tibbits and other academic groups, are identifying all sorts of promising areas of exploration — but perhaps the most interesting aspect of all this is the advances in 4D materials, which enable new ways of thinking. The concepts of self repairing jeans made from biological materials, flat packed vacuum wrapped furniture that self assembles when exposed to the atmosphere, and objects that assemble and disassemble depending on temperature all seem like science fiction, but are being explored today. Like printable human organs, we are years away from actualization, but the goals are in place to enable innovation.

When polymers and plastics first appeared in the late 1950s, there was a resulting explosion of innovation (the modern Lego toy brick was patented on January 28, 1958. It took another five years to find the right material ABS (acrylonitrile butadiene styrene) polymer to mass produce it). However, attempts at creating 4D objects with then-relatively crude chemistry experiments ultimately resulted in a few new toys and little else except some media buzz, while plastics mass production transformed the world.

Today, we are entering a new age that is the inverse, where the self assembling natural order of the universe is harnessed to enable small scale manufacturing of objects created by a new generation that will be "matter programmers, not computer programmers", as Skylar Tibbits put it.

This is already happening — Autodesk own Instructables, Thingiverse and defcad are increasingly busy, while the open source community is gathering 3 and 4D momentum. Tools such as vox.cad cross-platform open source voxel modeling and analyzing software (a voxel is a 3D volumetric pixel) are widely used today at MIT and inside the printer companies.

The materials are the most important component in all this. Despite all the current hoopla about home 3D printers, the cost of consumables and size constraints make the new generation of questionable value over lower small run manufacturing costs at a more industrial scale, as this blog post by Jonas Benzen argues. Today, 3D printers are mostly used for prototyping and industrial design in soft modeling materials.

Some of our printing concepts are an outmoded paradigm — the real advances are sure to come in the chemistry of the materials. As Daniel Dikovskey of Stratasys explained, it's the blend of multiple materials that are an important element of the material programming interface. This form of modern alchemy that programs properties into the materials to be created is the important new paradigm. Design principles that take advantage of the mutable properties of these amazing new materials are slowly taking shape, and while today's materials are limited, there is an explosion of activity and rapid advancement. Within four to five years, we should see highly sophisticated materials that can be programmed and printed, the result of a flowering of collaboration in a rapidly evolving and currently open, inclusive business space.

  • Good grief, what a bunch of technobabble.

    The materials science you are talking about is in its infancy, and is a whole lot more complex than discovering polymers. Each kind of physical transformation you are talking about will require its own major breakthrough. You aren't going to find a chemical process like polymerization that's going to give you temperature sensitive chemistry, photosensitive chemistry, air-sensitive chemistry, or water sensitive chemistry all in one shot.

    • Oh and

      It doesn't mention how Autodesk loves to rip its own customers off, by claiming perpetual ownership of the software the customers bought.

      ADSK bullies customers by trying to control what you do with their software after you've legally purchased it, and that's inexcusable. Screw Autodesk. Don't vote with your money for a company that treats you like a tool.

  • Horrific misuse of "4D"

    Good grief. How can you so horrifically use 4D? D=Dimension, not "whatever I want it to be."

    Objects that are "are able to change and mutate when exposed to water, temperature changes and/or air to self assemble" are cool and innovative, but not a new "dimension."

    • Minkowski vs Euclidean

      Four dimenesional Minkowski Space vs four dimentional Euclidean space.

      Now we can add four dimentional Stratasys Space to the mix which has nothing to do with the first two.

      And here I thought that 4D was "smellevision"

    • It's the Sales department

      They figured they wanted to go one better than 3D.

    • This is ZD, remember.

      Ziff-Davis loves to make up terms instead of doing legitimate writing. These hacks are basically spammers at this point, spewing out "articles" as a vehicle for the ads that they're buried in.

      Garbage.

    • 4th D

      The article is poorly written, the 4th dimension here is actually time.

      • Which,

        In this universe, is all it CAN mean.

  • blends of materials

    - this isn't an 'all in one shot' discovery, it's finding ways to program materials made up of different properties in different parts of their make up. Programming in rigidity or flexibility requires blends of different materials at designed points. The chemical combinations are what make this possible.

    This isn't like the discovery of ABS polymer, more about programming properties as materials are created. Overused phrase but you have to Think different' about this

  • Idiots.

    Time is the 4th dimension. Anything that changes over time is interacting in the 4th dimension. Consequently items that 'self assemble' when exposed to air ared 4 dimensional.
    Andrew Castle
    • Look,

      CHANGE over time is wholly beside the point of measuring time. If there is NO change over time, if the materials NEVER change from when they were printed (which of course is an impossibility) then the forth dimension does still exist, it just shows a bland continuation of the same-same.

      But time is still there, and in light of that wholly spurious fact, ALL 3d printers are in fact already 4d printers, as they COULD NOT EXIST IN THIS UNIVERSE, but for their time dimension.

      for the fact that nature does not patent its inventions.

  • Application Programmers Interfaces

    is the best joke ever.
    API's are Application ProgrammING Interfaces - they are not interfaces between programmers, they are interfaces used in programming.
    All these articles written by bloggers/jornalists are worthless. These people do not know what they are writing about, and the results are laughable.

  • Just add water???

    Add water and POOF it's a "REAL" pool table?
    .
    I "REALLY" doubt that will happen.

  • Thought this might be an informative article...

    ... not an infomercial for Autodesk. This whole 3D / "4D" printing thing is very interesting - the very beginnings of Star Trek-style replicators. But unless ET decides to cough up a few shortcuts to the process, it will be a long time before we see much of anything useful in the home. Note to ZDnet: please put a disclaimer at the front / top of your informercials. Thanks. :-p

  • footing the bill in a post GFC world

    Who is providing funds for this kind of bluesky level research (when so many folks are having trouble making basic ends meet?). Is it the CPU buying customers? Is it the people paying student fees to universities?
