Doctors have been employing 3D-printed tissue for years now. But even though the hype around 3D bioprinting has raised expectations that it will save lives and shorten donor wait lists, fully functional printed organs are not feasible yet. While we won't be seeing blood pumping printed hearts any time soon, getting a new nose could become easier.
 
Student Creates Super Fast ‘Membrane Based’ 3D Printer – Prints 40 x 40 x 100 mm Objects at 10 Microns in 12 Minutes
Student Creates Super Fast Membrane Based 3D Printer Prints 40 x 40 x 100 mm Objects at 10 Microns in 12 Minutes - 3DPrint.com

It is truly amazing how quickly the 3D printing space is developing. Just two weeks ago we stood stunned as a company called Carbon3D unveiled a new breakthrough 3D printing process called CLIP. This process can supposedly print objects 25-100 times faster than other SLA 3D printers. Then just a week after that, Gizmo 3D unveiled another super fast SLA-based 3D printer which looks to challenge Carbon3D as far as speed and resolution go. Then just earlier this week we reported on a Chinese company, called Prismlab, which has shown off their incredibly fast SLA line of 3D printers, rumored to be able to print 2,712.27 cm3 of material per hour.
 
I find this technology simply amazing. No more warehouses or transportation costs. You could go down to the Print Mart and get a part for your car or lawnmower, washer, whatever you need. Eventually it would be cheap. You pay a fee for the tech specs and the print.

If you have ever thought that having a 3D printer would be cool only to look at the price of 3D printers and decided the purchase isn't in your budget, the da Vinci Junior 1.0 3D printer might change your mind. This is the most affordable 3D printer on the market and sells for $349. With many other 3D printers running into the thousands of dollars, the Junior 1.0 is priced well for the masses.
 
China to install 3D printers in all its 400,000-plus primary schools
China appears to be heading towards a 3D-printed future after sources from within the government revealed that, over the next two years, the country is to offer each of its 400,000-plus primary schools a 3D printer.

In a country where production of goods is the highest in the world by a considerable margin, this would appear to show that the government has intentions of overtaking many of the other world’s most powerful nations in terms of their youth education.

We've only just begun to see the huge impact 3D-printing technology will have on manufacturing, and the aerospace industry is a prime example. Earlier this year we saw the first example of a 3D-printed jet engine, now GE has announced the first 3D-printed part certified by the US Federal Aviation Administration (FAA) for a commercial jet engine. The fist-sized T25 housing for a compressor inlet temperature sensor was fabricated by GE Aviation and will be retrofitted to over 400 GE90-94B jet engines on Boeing 777 aircraft.
 
Mattel hopes you'll design 3D-printed toys

Admit it: when you were a kid, you wished that you could design the toys that the stuffy manufacturers refused to build. Well, you're about to get that chance. Mattel and Autodesk are teaming up to let you design and customize 3D-printed toys through a "dedicated online hub" in the second half of the year. It's not clear just what freedom you'll have, although it wouldn't be shocking if you could craft your own Hot Wheels cars or Barbie accessories. They're likely to carry a premium over off-the-shelf toys, but they could be worth it if they encourage kids to create toys, not just play with them -- and hopefully, prevent the disappointment you probably felt when you were growing up.
 
Disney Research 3-D printer can combine fabrics, wiring
April 20, 2015
[+]
A team from Disney Research, Carnegie Mellon University and Cornell University have devised a 3-D printer that layers together laser-cut sheets of fabric to form soft, squeezable objects such as phone cases and toys. These objects can have complex geometries and incorporate circuitry that makes them interactive.

“Today’s 3-D printers can easily create custom metal, plastic, and rubber objects,” said Jim McCann, associate

3d printing technology is interesting. The idea that you draw some device then print is very promising.

3d printing is great for prototyping and mold manufacturing, but for metal 3d printers to be a real replacement to casting/cutting there is some issues:
1) is the mechanical properties -yield & ultimate tensile strength- of printed metal parts are comparable to that of casted and heat treated parts? as to my knowledge the layer-by-layer approach may cause the strength not to be equal in all directions. Are the mechanical properties predictable?

2)is 3d printed metal parts really printed?
i mean isn't it necessary to apply heat treatment and grinding/polishing steps?
if these extra steps are necessary, isn't casting still a faster and more reliable alternative?

a real advance in the field should answer the previous issues, just announcing that some devices are 3d printed (without answering the reliability of these devices or the extra steps) is not an advancement in my opinion.
 
’4-D printing’ objects that morph based on stimuli like water and heat

Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong(UOW) are developing 3-D printed materials that morph into new structures under the influence of external stimuli such as water or heat. They refer to this process as “4-D printing,” where the fourth dimension is time.
The researchers are currently exploring a use in manufacturing a valve that actuates in response to its surrounding water’s temperature.

The development of 3D printer technology has been rapidly accelerating, boosted in a large part to the open source community and world-wide sharing of information. There are now literally dozens of brands of 3D printers on the market at all price points, but Buzz Technology Limited, out of London, is looking to stand out from the crowd with its Industrial Revolution III printer (or IR3 for short) that can embed wiring within plastic components using conductive material.

It's one thing to 3D-print something as advanced as a jet engine, but it's another to fuel it up and push the start button. That's the step that GE Aviation took when It recently fired up a simple jet engine made entirely of 3D-printed parts in a test stand normally reserved for commercial jet power plants.

Unveiled at Rapid 2015 in Long Beach, California, TE Connectivity’s exercise in 3D printing demonstrates the ability to design a motorcycle on a computer, print it in plastic, add tires and a motor, then take it for a spin. In fact it may take a little more than that to actually end up with a complete functioning motorcycle; nonetheless, the concept is nothing short of exciting.
 
Lots of links to what other people are doing, or want to do, or hope to some day be able to do, but is there anyone here with actual hands on experience with gcode, or steppers, or electromagnetic interference causing false triggers, or beam deflection, or any of the other things you need to deal with when building or running one of these machines?

Australia is wasting billions of dollars of potential value by shipping its world-beating titanium reserves out of the country as raw ore. That's why CSIRO's Lab 22 is making millions of dollars' worth of 3D printing facilities available to Australian businesses in an effort to kick-start a local additive manufacturing revolution that could add billions of dollars' worth of value to the country's raw titanium exports.

I didn't say they didn't work. I was just wondering if this thread amounted to more than an endless list of links to advertisements and press releases found on the web. I enjoy working with a CNC. It's one of my retirement hobbies. I have a mill, but other than having a spindle instead of an extruder, they are basically the same type setup. I guess I was just looking for more than a list of what is available on the market.
 
3-D printers poised to have major implications for food manufacturing



The use of 3D printers has the potential to revolutionize the way food is manufactured within the next 10 to 20 years, impacting everything from how military personnel get food on the battlefield to how long it takes to get a meal from the computer to your table, according to a July 12th symposium at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists (IFT) in Chicago.
The price of 3D printers has been steadily declining, from more than $500,000 in the 1980s to less than $1,000 today for a personal-sized device, making them increasingly available to consumers and manufacturers Although they are not widely used in food manufacturing yet, that availability is fueling research into how they can be used to customize foods or speed delivery of food to consumers.
"No matter what field you are in, this technology will worm its way in," said Hod Lipson, Ph.D., a professor of engineering at Columbia University and a co-author of the book Fabricated: The New World of 3D Printing. "The technology is getting faster, cheaper and better by the minute. Food printing could be the killer app for 3D printing."
