83 year-old woman got 3D-printed mandible 3D printed mandible (credit: University of Hasselt) The University of Hasselt (Belgium) has announced that Belgian and Dutch scientists have successfully replaced a lower jaw with a 3D printed model for a 83 year-old woman, 3Ders.org reports. According to the researchers, It is the first custom-made implant in the world to replace an entire lower jaw. Normally it takes a few days to produce a custom implant, but with 3D printing technology it takes only a few hours.
There's nothing like being able to hold something in your hand and inspect it. You can look from all angles close or far and can use your sense of touch to aid in understanding completely what you've got. That's exactly the approach Hawaiian neurosurgeons at the Tripler Army Medical Centre are taking. They're able to plan their surgeries more easily and accurately. Another interesting capability is using the 3D model to explain the upcoming surgery to family members in a more meaningful way. Neurosurgeons Are 3D Printing - Fabbaloo Blog - Fabbaloo
Organovo, the bioprinting startup that hopes to eventually print whole replacement human organs, has struck agreements with two pharma companies to assist in drug testing. Organovo will print tiny scaffolds on which human tissue can grow into lifelike shapes. These shapes tend to be better grounds for drug testing, as cells in a simple petri dish tend to behave differently than they do in a human body. Testing efficiency should improve.

Scaffolds are three dimensional structures Scientists at the Fraunhofer Institute have developed a new way to 3D print bioscaffolds. Scaffolds are three dimensional structures on which organic material (cells) may grow into properly formed tissue structures. Typically the scaffold then dissolves, leaving the newly formed tissue. The new process involves hitting a liquid concoction mixture of polymers and proteins with a microchip laser pulse - but one only picoseconds in duration. The extremely short pulse is sufficient to cause reactions that solidify the liquid, but not long enough to damage any of the biomaterial.
3D Printing biomaterial with stem cells Earlier this week our design of the week featured Icarus Had a Sister, by Masters & Munn. While we're certain you'll agree the work is astonishing, we also must tell the incredible story of how it came to be, as revealed during a long conversation at the close of the 2013 3D Printshow. The work may have been recently completed, but in fact it germinated some nine years ago, while André Masters made a critical life transition. You see, Masters was a traditional model-maker, one who made expert models with his bare hands, skill and plenty of workshop tools.
More Metal - This Time Saving Lives! Both ProMetal and Sintef have been working on metal printing processes, quite different from traditional plastics and powders of other 3D print processses. One of the barriers to more common use of 3D printing (aside from cost and print time) is the robustness of the printed objects. If only they could be printed in something stronger, like, say, metal?
Objet's Clear Bio-Material Commercial 3D printer manufacturer Objet has released a new very interesting print material: MED610, which is a transparent bio-compatible substance. You might think that making a clear, safe substance would be easy, but it's not. In order to qualify for such a designation numerous tests and certifications are required, and that's the tough work that Objet has completed. According to their description:
Printing Blood Vessels - Fabbaloo Blog - Fabbaloo Printing solid objects is pretty easy: you just extrude/fuse/sinter/flash the layers and you've got your whatever-it-is-you-wanted. It's easy because typically these 3D prints are a uniform material all the way through. Occasionally experiments are done with multiple materials and one commercial 3D printer maker (Objet) has a technology that can print mixes of two different materials, but by and large 3D printed objects are pretty simple in structure.
Organ Printing Pondered - Fabbaloo Blog - Fabbaloo We encountered several reports dealing with the fantastic idea of printing human organs using 3D printing technology. The premise is to deposit cells in the appropriate shape. Various prototypes have been attempted, including liver tissue, branched vascular trees and cartilage. The bad news is that the experts predict it could be decades before such technology is ready for common use.
transform medical 2D CT or MRI data into usable 3D models We ran across an interesting video that talks about Materialise's ventures into the medical manufacturing space. We've posted about medical uses of 3D print tech before, but Materialise specializes in this niche, and have for quite some time. Materialise produces 3D software specifically designed for this market: Mimics, which can transform medical 2D CT or MRI data into usable 3D models.
Did you ever take a very close look at your fingers? They are incredibly complex machines, with not only shape and texture, but also motion. Imagine if fate caused the loss of one or more of them? There are solutions today, such as those produced by Didrick Medical, who make a kind of finger-harness that fits over the hand and implements an "active-function artificial finger prostheses". The design permits a variety of finger loss scenarios to be resolved. This is their "X-Finger" product. Fingers Restored By 3D Scanning - Fabbaloo Blog - Fabbaloo
New Scientist reports on a medical breakthrough using 3D printing: exact replicas of finger bones have been produced. Christian Weinand of Berne Switzerland has been testing a new technique in which a 3D model of a finger bone is fed into a 3D printer, and an exact duplicate is printed. By using a suitable print medium (in this case "tricalcium phosphate and a type of polylactic acid - natural structural materials found in the human body") the resulting artificial bone can be inserted into the body and take over for the failed bone. 3D model of a finger bone
Objet's 3D printers seem to be taking hold in various medical applications, according to information passed our way. Here are four interesting approaches: Biorep Technologies creates tools for diabetes researchers and has created a "Pinch Valve" for indexing fluids and avoiding contamination of equipment and fluids, as well as a silicone membrane petri dishArch Day Design creates tiny objects that interlock inside arthroscopic surgery patients to guide the microscopic tools. Ivivi Technologies uses Objet tech to rapidly create prototypes for a variety of non-invasive medical applicationsOrchid Orthopedic Solutions uses 3D tech to rapidly develop new implant applications for the orthopaedic, dental and cardiovascular markets. medical applications & Equipment
