3D Pen – Draw 3D Art!

The world’s first 3D printing pen: Yours for just $75

The 3Doodler, 3D printing pen

Come September, if everything goes to plan, the world’s first 3D printing pen will go on sale for $75. The pen, called the 3Doodler, essentially allows you to lift your flat sketches off the paper — or, if you wish, to actually draw in three dimensions.

3Doodler is a Kickstarter project, and in under 24 hours it has obtained more than $500,000 in pledges — significantly more than its $30,000 target. As you can see in the video below, the inventors have already created an impressive prototype — and now it’s time to bring the 3Doodler to market. The target price is $75 for a September 2013 release. The inventors say they have already located a Chinese manufacturer who is capable of meeting these targets. The final device should 24mm (1in) thick and weigh less than 200g, with an external power brick that accepts 110-240V.

In essence, 3Doodler is a standard 3D printer, but your hand controls the print head instead of a bunch of computer-controlled motors. (See: What is 3D printing?) Inside the 3Doodler is a filament feeder (which accepts ABS or PLA plastic), a heating element, and an extruder — and that’s about it. The melted plastic comes out of the extruder and very quickly sets. As far as we can tell, the plastic oozes out of the extruder at a set rate — so depending on whether you want a thin (weak and flexible) or thick (strong and rigid) line, you move the 3Doodler quickly or slowly. For strength and flexibility, you just go back and forth over the same section, building up a web of plastic tendrils (like in the Eiffel Tower above).

Judging by the massive support for 3Doodler on Kickstarter, it’s safe to assume that people are really excited at the concept of a freehand 3D printer. It’s not hard to see why, though, if you were a child who dreamt of drawing sketches that literally jump off the paper. The actual reality of freehand 3D printing might be a little more complex than most users bargain for, but to that end the inventors have teamed up up with professional artists to provide 3Doodler backers with templates/stencils that you can simply fill in. The Kickstarter page also seems to lack any evidence that 3Doodler is capable of drawing straight lines, but hopefully it’s just a matter of using a ruler.

Moving forward, this could be a very exciting stepping stone for inventors and hobbyists alike. While 3D printers have revolutionized rapid prototyping tool, the 3Doodler is even faster; it adds a whole new dimension (!) to back-of-the-napkin brainstorming. To begin with, I suspect it will be quite hard to create meaningful sketches with a 3Doodler, but in time — and with a whole range of usability tweaks and add-on accessories that I’m sure will follow — the 3D printing pen might become as ubiquitous as the 2D Bic ballpoint.

Printing Food

3D printers are the technology that will change everything ab0ut our lives.  I was just having dinner with friends and said if you can put polymers in a 3d printer and print out three dimensional objects, why not put food paste, texture, flavor packets and coloring and print food?  In essence, you could transmit a “recipe” to a printer as easily as a structural diagram, and food is just as easy to layer as polymer.  I had no idea it would be tried so soon.  Get drunk late at night and want to head to Taco Bell?  Want a pizza delivered during the big game?  Why not print one out?  Go to pizzarecipe.com, pick out your favorite, download to the printer, voila!  Star Trek Replicators now.

A single 3D-printed burger currently costs over $300,000 to make

3D printing might be the wave of the future, or it might just end up a niche hobby that’s pretty cool but ultimately too expensive and complicated to ever take off. Whatever that fate may be, startup Modern Meadow is throwing its hat into the 3D printing ring, but rather than printing plastic trinkets or gun parts, it plans to print edible meat.

We’ve mentioned Modern Meadow – a company that is practicing a variant of 3D printing, called 3D bioprinting — before. Instead of using resin like standard 3D printing, or a material more easily sent through a printer for food-printing like melted chocolate that then hardens, Modern Meadow uses material somewhat creepily called “bioink”.

In order to print live cells, the engineers perform biopsies on animals and collect stem cells, or other special cells. Because stem cells are basically magical (this not a technical term), they can not only turn into other cells, but replicate themselves. Once they replicate enough times, the engineers load them into a bioprinter cartridge, which creates something of a bioink — a material made of many live cells. When the bioink is printed, the living cells link together and form living tissue.

Modern MeadowWhen using 3D bioprinting a hamburger as an example, Professor Gabor Forgacs — part of the father and son founders of Modern Meadow — notes that the actual shape of the food isn’t too much of a hurdle, as it’s simply a round, relatively 2D patty. Another benefit to producing edible meat is that the live tissue can die afterward, as consumable meat normally isn’t living tissue, so a method of preserving the tissue’s life isn’t really required.

Though it might be easier to print edible, dead-tissue meat, Modern Meadow is facing a couple fairly large hurdles. For one, convincing the world to eat lab-grown meat might not be so easy. Another significant hurdle is that though Modern Meadow hasn’t grown something like a burger or steak as of yet, the price of one would be astronomically high. Another team of researchers at Maastricht University in the Netherlands has been growing animal cells to produce strips of lean muscle, with the goal of creating an artificial hamburger. Though the team doesn’t use bioprinting, they do use a somewhat related process of having stem cells replicate and create live tissue in a mold. Unfortunately, creating an entire burger would currently cost over $300,000.

If this all seems a little nutty, Modern Meadow has managed to raise some backing from prominent figures, such as Peter Thiel, who was one of Facebook’s early investors. There’s no word yet on when the company will be able to print a burger (or even a slider!), but if it can, it will be interesting to see how much it’ll cost, and if people can be convinced that “synthetic” meat is truly edible.

Human Enhancement Dangers

In my opinion, the two technologies that will effect us the most in the immediate future, are 3d personal printer manufacturing, and human enhancement.  We are nearing a time when we can replicate or build nearly anything in our home, and in which we will no longer be human.  We will start human, but will be updated to receive technology, correct defects, and enhance our abilities.  Here is a cautionary story on the latter topic:

Scientists raise the alarm on human enhancement technologies

The Royal Society, along with the Academy of Medical Sciences, British Academy, and Royal Academy of Engineering, recently concluded a workshop called Human Enhancement and the Future of Work in which they considered the growing impact and potential risks of augmentation technologies. In their final report, the collaborative team of scientists and ethicists raised serious concerns about the burgeoning trend, and how humanity is moving from a model of therapy to one in which human capacities are greatly improved. The implications, they concluded, should be part of a much wider public discussion.

Specifically, the report expressed concerns about drugs and digital technologies that will allow people to work harder, longer, and smarter. The resulting implications to work and human values, they argue, may not necessarily be a good thing. It’s quite possible, they argue, that employers will start to demand (either implicitly or explicitly) that employees “augment” themselves with stimulants such as Aderall.

Scientists raise the alarm on human enhancement technologies

Similarly, the workshop considered the potential for other smart drugs that can enhance memory and attention, as well as physical and digital enhancements such as cybernetic implants and advanced machine-interfacing technologies.

From the report:

Work will evolve over the next decade, with enhancement technologies potentially making a significant contribution. Widespread use of enhancements might influence an individual’s ability to learn or perform tasks and perhaps even to enter a profession; influence motivation; enable people to work in more extreme conditions or into old age, reduce work-related illness; or facilitate earlier return to work after illness.

At the same time however, they acknowledge the potential efficacy and demand for such technologies, prompting the call for open discourse. Again, from the report:

Although enhancement technologies might bring opportunities, they also raise several health, safety, ethical, social and political challenges, which warrant proactive discussion. Very different regulatory regimes are currently applied: for example, digital services and devices (with significant cognitive enhancing effects) attract less, if any, regulatory oversight than pharmacological interventions. This raises significant questions, such as whether any form of self-regulation would be appropriate and whether there are circumstances where enhancements should be encouraged or even mandatory, particularly where work involves responsibility for the safety of others (e.g. bus drivers or airline pilots).

Indeed, the details of the report, while most certainly reasonable, are also exceedingly obvious. In a way, it’s as if the workshop participants are late to the show and only now trying to get the word out. And in fact, given the popularity (and rampant misuse) of stimulants such as Provigil and the tremendous interest in nootropics (i.e. cognitive enhancers), the report does seem long overdue.

The panel’s recommendations, such as further investigations into ensuring safety, affordability, and accessibility are most certainly welcome. And their suggestion that some of these enhancement technologies — whether they be pharmaceutical, regenerative medicines, or cybernetics — should be regulated by the government is spot on. Given the potential for personal misuse — not to mention the potential exploitation by employers — would most certainly necessitate the need for regulatory oversight.And perhaps most encouragingly, rather than reacting hysterically and calling for an outright ban on enhancement technologies, the panelists have outlined a roadmap for getting these technologies integrated into our lives in a safe and effective way.

Personal Manufacturing Through 3D Printing

There is a revolution coming in the way we live that has already started.  You are of course familiar with taking a file and printing it on your printer.  It makes a two dimensional image, first in black and white, now in amazing color.  But imagine using a printer that prints in THREE dimensions.  Instead of ink, it uses steel, plastic, fibers, rubber, or other materials.  You design and object on a computer file, then “print it” using these materials.  You need shoes, put in the rubber, plastic, etc., download your own shoe design and size to the printer, print them out and put them on your feet.

Sound crazy?  It is here right now.  As prices come down, expect the next generation of our children to grow up, buy a design online, customize it, and print manufacture their own items at home.  It is the closest thing to a Star Trek style replicator we have come up with so far.  Here is a video that explains the process:

Three dimensional printing will bring personal manufacturing to the world.  Amazing.
