At the daybreak of speedy prototyping , a coarse postulation was that 3D printing would transform manufacture , spurring a consumer revolution that would put a printer in every home . That has n’t quite happened—-and like so many emerge applied science , speedy prototyping has found its foothold in a astonishingly different field : Medicine .
The following studies and projects exemplify some of the most fascinating examples of “ bioprinting , ” or using a figurer - controlled machine to foregather biological affair using constituent ink and super - tough thermoplastics . They range from rebuild major section of skull to print scaffolding upon which bow cells can arise into new osseous tissue . More below — and look out for more3D printing weekcontent over the next few twenty-four hour period .
Osteofab is a Cartesian product made by a British company calledOxford Performance Materials . OPM got into the clientele by sell a high - performance polymer often used in aesculapian implant — a thermoplastic resin called polyetherketoneketone — in raw form . But over the past few years , the troupe has also open up the software of the stuff , principally through additive manufacture . In February , anAmerican patient receive an FDA - approved skull patchmade of the material , which had been carefully molded and print to jibe 75 percentage of his alone skull geometry . [ Osteofab ]
Dude Has 75 pct of His Skull Replaced By 3D - Printed Replica
A big problem with the thought of “ printing ” young skin is how hard it is to revivify a fussy hide tone in every kind of light : Because our skin is so unparalleled , thin , and mutable , it ’s hard to perfect an accurate replication . There are too many interesting studies to discuss in a short paragraph , but two highlights : Wake Forest scientist James Yoo is work on machine that can actuallyprint skin now onto burn victimsas part of a Defense Department - funded grant , while scientist at University of Liverpool are using cautiously - calibrate 3D scanner they ’re using to entrance samples of each subject area ’s be tegument , which allows them to print a more accurate plot of land .
The enquiry is on-going , but the team plans to create a “ skin database ” of the appropriate samples , which could be tapped into from remote hospitals without the cameras needed to capture a subject ’s own skin . [ Gizmodo;PhysOrg ]
There ’s Now a 3D Printer That Can Replace Human Cartilage
create prosthetic ear , noses , and chins are often a painful , expensive , and arduous experience for patient role and doctor both . A UK industrial designer namedTom Fripphas spent the past few years collaborating with University of Sheffield scientists to 3D print a cheaper , easier - to - make facial prosthetic . Their unconscious process involves 3-D scan a affected role ’s boldness ( much less invasive than casting it ) , model a replacement part , and printing it using paint , starch , and medical mark silicone .
An added fillip : When the prosthetic wears out ( unavoidably , they do ) , the part can be inexpensively re - printed . [ The Guardian ]
Last week , Fripp and the squad at Sheffield unveiled the consequence of testing the same process — on eyes . Prosthetic eyes are expensive to make , since they ’re hand - painted , and can often take months to complete . Fripp ’s printer can become out 150 eyes an time of day — and the details , like iris color , size , and bloodline watercraft , can be easily customize found on each patient ’s want . [ PhysOrg ]
As electronic devices — from droning to medical implant — get smaller , scientist have struggled to manufacture battery small enough to power them . But a squad of Harvard railroad engineer is 3D print microscopical batteries that are as small as a slice of moxie . The team explains :
… the research worker created an ink for the anode with nanoparticles of one lithium alloy oxide compound , and an ink for the cathode from nanoparticles of another . The printer deposited the inks onto the teeth of two gold comb , creating a tightly interlaced heap of anode and cathodes . Then the investigator packaged the electrodes into a lilliputian container and meet it with an electrolyte answer to fill out the bombardment .
They could eventually power medical implant — like these ones — that are being held up by power issues . [ Harvard ]
3D - printed implant — like jawbones — have been around for several year . But a fistful of research worker are experiment with print actual replacement bone . For good example , a University of Nottingham scientist named Kevin Shakeshaff has developed a bioprinter that make a scaffold of polylactic acid and gelatinlike alginate — which is then coated in adult stem cells . According to Forbes , the scaffolding will disband and be replace by novel bone increment within roughly three months . [ Forbes ]

We may be able toprint organs , but part of the trouble with these manufactured tissue paper is make a functioning circulative system to go with it . Günter Tovar , a German scientist who heads up the Fraunhofer Institute for Interfacial Engineering and Biotechnology , is lead a project called BioRap that ’s developing 3D - printed blood vas using a commixture of synthetic polymers and biomolecules . These printed systems are being tested in beast — they are n’t yet ready for human race — but they could finally enable printed Hammond organ transplant . [ Fraunhofer Institute ]
