When it comes to designing a home from the ground up, home builders often have a difficult time showing customers the completed results from drawings alone. Customers want to see how their house will look – before it is actually built, so they can make needed changes beforehand.Thanks to 3D printing technology though, that is now possible. The Plan Collection is an online house plan provider that has recently announced that they are incorporating 3D printing into their business, to allow customers to receive a 3D printed model of their prospective homes – in a smaller scale. It gives the homeowners a 3D printed model of their home, which is like a physical blueprint that they can actually see.
The 3D-printed liver replicas, made of transparent material threaded with coloured arteries and veins, could help surgeons prevent complications while performing liver transplants or removing tumours, a path-breaking research shows.
Till date, surgeons look at a magnetic resonance image (MRI) or a computed tomography (CT) scan to visualise the liver and plan the operation.
"We provide the surgeons with a physical model that is 100 percent identical to what they would encounter in surgery when they operate," Nizar Zein, chief of hepatology at the Cleveland Clinic in Ohio, was quoted as saying.
It takes away some of the potential surprises that would be found at the time of surgery.
To create the artificial liver, the researchers combined the MRI and CT scans that patients have already undergone and then recreated the 3D shape of the organ.
These models were anatomically accurate in terms of volume and location of vessels in the liver.
Using these models, the team created the 3D-printed organs using a transparent polymer, then dyed the main blood vessels and the bile ducts.
The researchers are now developing similar methods to guide complicated surgeries, such as hand and face transplants, and pancreatic tumour removals.
The new liver replica could also be used to train medical students in the techniques needed for surgery, Zein added in a study published in the journal Liver Transplantation.
Relevantly, a US company in January claimed to have developed the world's first multi-material full-colour 3D printer capable of making objects of hard, soft and flexible polymers.
The 3D printer developed by Stratasys features "triple-jetting" technology that combines droplets of three base materials, reducing the need for separate print runs and painting.
Video transcript: Riding high on the wave of new food 3D printers such as the chocolate, vanilla sugar, mint, sour apple, cherry and watermelon flavoured output of the Chefjet Pro by 3D Systems that will launch later this year, the Michelin-starred Barcelona restaurant Dos Cielos has announced that its chefs are experimenting with some 3D printed fine cuisine.
Twin team Javier and Sergio Torres are turning to new food tech in the form of Natural Machines' food 3D printer — The Foodini. More will surely follow but these pioneers are the first with the unique capacity of 3D printers to create extraordinary and refined shapes to complement their restaurant's panoramic skyscraper views and 'full sensory experience' ethos.
The duo are using the 3D printer as an intricate artistic food preparation device, rather than 3D printing whole dishes in one. According to the pair, they are thankful that their hands won't become obsolete, as the machine can't make food taste good; it doesn't cook it for you. What it does is help with the visuals and helps to create shapes that wouldn't have been possible before. The twin team has already ordered a [3D printer] as they have so many ideas to try out. We here at 3DPI.tv can't wait to see the results!
Scientists have designed an artificial heart membrane that may one day revolutionize pacemakers.
Using a 3D printer, high-resolution images and computer modeling, researchers at the University of Illinois and Washington University created a 3D replica of a rabbit’s heart then used it as a template to produce a thin, flexible sheath of silicon that fit snugly around the heart. Next they fitted the custom-made pouch with a web of sensors and electrodes that monitored the heart and kept it beating in a steady rhythm.
Lead researcher John Rogers, a materials scientist at the University of Illinois, said the device acts like an artificial pericardium, the thin, outer sac that wraps around the heart like a tailored garment.
“The goal was to create a membrane that fit tightly but not so tightly that it interfered with the normal beating of the heart,” he said.
A new bioprinting method has created intricately patterned 3-D tissue constructs with multiple types of cells and tiny blood vessels. Researchers are hopeful that printing living tissue will soon be possible.
3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes. With the new technology for creating cells and blood vessels, the scientists behind the project regard this as the foundational step toward creating 3D living tissue. Currently when scientists have tried to print layers of tissue, cells on the interior starve for oxygen and nutrients, and have no good way of removing carbon dioxide and other waste. So they suffocate and die.
This new research has focused on tiny, thin-walled blood vessels that nourish the tissue and remove waste.
Getting this right is key to creating living cells. In theory, the ability to form functional vascular networks in 3D tissues before they are implanted not only enables thicker tissues to be formed
Video Transcrip: Hospital officials at the Kosair Children's Hospital have stated that 3D printing was used to support an infant pediatric heart patient for the first time recently. Doctors operating on baby Rolande, a 14-month-old with heart defects studied a three dimensional replica of the child's heart to aid successful surgery outcomes. The infant's heart was riddled with defects before the surgery at the Hospital and his surgeon, Dr. Erle Austin, said that he had anticipated that the surgery would be tricky and thus sought a model that offered more detail than traditional 2D scans.
Dr. Austin's team contacted the University of Louisville J.B. Speed School of Engineering, which used a 3D printer to create a polymer model of the heart to provide vital insight ahead of the planned surgery.
Once he had a model, it was clear what needed to be done and how he could do it. The Cardiothoracic surgeon was able to reduce exploratory incisions, reduce overall operating time and also even ensure that Roland would not require any sequential or consequential follow-up operations for this relatively high-risk surgery.
Roland, the son of Par Tha Sung and Sang Ceu Lian of Owensboro, Kentucky, U.S.A., was born with heart problems that included a hole in his heart, as well as misaligned aorta and pulmonary arteries, which, if left untreated, would have been fatal.
The engineering team behind this wonderful application of 3D printing created the model and end-use 3D print in just 20 hours on a MakerBot Replicator 2X desktop 3D printer.
3D printing has hit the streets in Taipei, Taiwan with the mobile plastic shredder and 3D printer called the “Mobile Fab.” The Mobile Fab is a bike that’s equipped with a mini-factory of sorts. Complete with a shredder for plastic, a filament extruder, and a 3D printer.
The goal of the Mobile Fab project is ‘to promote 3D printing on the streets’ using material from recycled plastic products like old bottles.
While most 3D printing filament replacement cartridges are expensive, the Mobile Fab can turn recyclable bottles into free 3D printing material, and it can all be done immediately – on the streets.
Han Kaiyu, the co-creator of the Mobile Fab, along with three friends, founded the “Fabcraft Design Lab” last year. The Mobile Fab was then created out of that lab.
The environment that we interact with on a daily basis is made up of just as many invisible, immaterial elements as physical objects. Internet data, your tracked run or route to work, sound and CO2 levels, time or any other kind of algorithmic or ambient information surrounds us constantly – and although we cannot see this data, there are certainly many ways in which it can be illustrated. The digital structures on which we rely are only becoming increasingly important. And with this in mind, understanding and representing this information has started to fascinate more and more people.
In sync with this development of interest is a development of technological tools. All sorts of tracking, scanning, calculating and measuring devices can be used to make sense of the invisible information that surrounds us, and what often intrigues is the chance to make these invisible processes material. Alongside particular software and hardware platforms, 3D printing is certainly allowing us to make solid representations of the digital or ephemeral world, so let’s take a look at some of the projects that are working towards this aim.
3D printing is considered additive manufacturing. In this process, layers of material (plastic, wood , metal, sand, sugar, or even chocolate) are laid down in a pattern, one layer at a time, until the 3D object is created.
At end of last year, an evolved version of the garbage recycling bike was seen on the streets of Taipei in Taiwan. It takes PET bottles and plastic bags and turns them into fashionable 3D printed products in about half an hour.
This bike, a mobile mini-factory is called the Mobile Fab. It consists of a plastic shredder, a filament extruder and a 3D printer. Its goal is 'to promote 3D printing on the streets' using material from recycled plastic bottles.
This week saw Stratasys release two new dental specific 3D printing items: the Objet Eden260V Dental Advantage 3D Printer for dental and orthodontic labs; and VeroGlaze, a dental material for natural looking dental models .
