Amid the tough-edged replicas of superheroes and navy tanks that embellished the expo's 3-d printing space stood a device that prints tiny medical implants that dissolve within the human body. some other printer makes use of a aggregate of conductive inks and filaments to print quadcopters already embedded with the electronics that permit them to hover in the air. One corporation displayed a prototype of a 3-D-revealed clinical tool which could automatically sew up sufferers after surgery.
The message those businesses are sending couldn't be clearer: three-D printing isn't always just for makers anymore. an increasing number of, this cutting-edge technology is turning into a ought to-have device for medical doctors, researchers and engineers, in step with Nick Liverman, CEO and founder of vintage world Labs (OWL), a Virginia-based totally agency that designs dissolvable 3D-printed implants.
"[Most] 3-d printers are made to print what's already obtainable — a version model of the Eiffel Tower or a chess set. but you'll use our printer to build things that aren't developed yet: theories, studies. it's office work that now can grow to be real," Liverman advised live technological know-how.
OWL's MC-1 and MC-2 printers have been both on display at CES. The machines use a manner known as stereolithography (SLA), in which lasers harden layers of liquid plastic, or resin, into three-dimensional shapes. This approach sets OWL's printers aside from other 3-D printers in the marketplace, along with MakerBot's Replicator or the Ultimaker 2, that use a process referred to as fused deposition modeling (FDM), now not SLA.
In FDM, heated plastic is released layer by means of layer onto a platform to create a 3D object, a process that consequences in a far much less distinct product with a rougher finish than objects created the use of SLA. other 3-d printers on the market also use stereolithography to construct what Liverman calls "high-resolution" items. however OWL's machines are more superior than those printers, in step with Liverman, who said that his organization's machines print objects that are 2 hundred times extra correct, or truer to their original design, than items created with different SLA printers.
OWL is currently using its top notch-correct printers to deliver complex ideas to existence. as an instance, most cancers researchers who need to deliver localized treatments to sufferers are using OWL's machines to construct what Liverman called "microfluidic gadgets." Such devices are especially unique, containing tiny channels that flow into prescribed drugs right into a affected person's body.
"you could additionally build custom implants, like tissue scaffolds," Liverman said. "you may inject stem cells into the scaffold which you construct with the printer and then you can, for instance, do a cartilage replacement on a knee." [7 Cool Uses of 3D Printing in Medicine]
at some stage in cartilage replacement surgical treatment, the scaffold containing the stem cells would be implanted within the knee, where the stem cells grow to update the missing cartilage, Liverman stated. The scaffold, which is outlined with what Liverman known as "bioreabsorbable material," sooner or later dissolves harmlessly in the frame. OWL is currently running on obtaining long-term FDA popularity of the resins utilized in its printing technique. this will permit the business enterprise's customers, which encompass NASA and Virginia Tech, to print such scaffolds and other medical-grade devices and use them in actual-global settings, no longer just in the lab.
OWL wasn't the only innovative 3-D printing corporation hawking its wears at CES. Harvard-based startup Voxel8 was there, too. The organisation's 3-d printers have two extruders — one that prints in conventional plastic filaments and every other that squirts out incredibly conductive ink.
"Coming off the printer isn't only a plastic form but a fully functioning digital tool," said Voxel8 co-founder Daniel Oliver.
At CES, Voxel8 showed off a quadcopter revealed with its gadget. The flying toy changed into built in layers — the structure of the tool changed into published in plastic with cavities carved out for the control common sense board and the automobiles. The printer then used conductive ink (which takes the place of wires) on top of the plastic, connecting these electric components. The ink, along with the imbedded electronics, eventually got included up with greater layers of plastic.
Of direction, Voxel8's printer is designed to do greater than just print tiny drones. The employer will also be freeing new printing substances with a purpose to try its hand at printing resistors, sensors and, for destiny fashions of its printer, even lithium-ion batteries. those items are further to the custom circuit forums that Voxel8's printers have already perfected.
"we're speakme about printing out a circuit at your desk in much less than 30 minutes," Oliver stated. This represents a substantial development over earlier options for printing custom circuit forums, a process that, Oliver stated, traditionally ought to take up to a month to complete.
Engineers and developers will now not handiest be capable of recognize their designs an awful lot faster with a Voxel8 printer, they'll also be capable of attempt out unconventional geometries for their electronics, Oliver stated. for instance, in place of trying to get a square circuit board to healthy interior a curved object, it'll now be feasible to customise the form of a circuit so that it suits inside objects of any shape or length.
