Could 3D printed microscopes improve water testing?

Manual tests for safe drinking water can be slow and error-prone. A team of academics is trying to change that

WaterScope creates 3D printed microscopes to test water quality.Like many people, Alexander Patto was keen to move away from academia after his PhD. He wanted a job that would have a tangible impact on the world, so when an opportunity came up to investigate water testing in the developing world, he jumped at the chance. Together with a team of academics from the University of Cambridge, Patto, a biologist, worked on a simple way of testing bacterial contamination in drinking water.

“The current systems are very slow and complex,” says Patto. To get a robust result “there is a lot of manual sampling”, which can also lead to “a lot of human error”, he says. “What we’re trying to do is make it very, very simple, so that anybody can do a test, regardless of their skillset [and the] resources available, and still get a result that is scientifically robust.”

Recognizing the need for evidence-based recommendations in the sector, these guidelines have been developed over a period of two years, in review of over 500 recent papers published on the topic.

As the abstracts states, “The recommendations provide guidance for approaches and tools in medical 3D printing, from image acquisition, segmentation of the desired anatomy intended for 3D printing, creation of a 3D printable model, and post-processing of 3D printed anatomic models for patient care.”

3D printing part of an ‘unparalleled period of invention’

3D printing technology applications come alive in applications ranging from developing packaging machinery to producing personalized medical devices to printing custom medications in a patient’s home.

The FDA acknowledges that “advances in material science, digital health, 3D printing, as well as other technologies continue to drive an unparalleled period of invention in medical devices.”

The perspective comes from a Nov. 26, 2018 statement by FDA Commissioner Scott Gottlieb and Jeff Shuren, Director of the Center for Devices and Radiological Health, outlining transformative new steps to modernize FDA’s 510(k) program to advance the review of the safety and effectiveness of medical devices.

3D method uses patients’ own cells to repair tissue damage

OCTOBER 17, 2018: A technician at OrganOvo works with a bioprinter in one of the labs clean rooms to create a 3-D tissue sample. Courtesy of OrganOvo.Patients waiting for an organ transplant may soon have a new treatment option — print out the organ or tissue they need using a revolutionary form of 3D printing that may one may day eliminate the need to wait on transplant donations.

Organovo, a biotech company in San Diego is leading the revolution in bioprinting and Boston area researchers are weighing the benefits of 3D-printed tissue.

“It’s about personalized and customized treatment,” said Xuanhe Zhao, a professor of mechanical engineering at Massachusetts Institute of Technology. He said 3D printing could eventually eliminate the need for transplant donations.

Lessons for medical device manufacturers using 3D printing

Last month, legal practitioners, industry, and academics gathered at The Legal, Regulatory and Business Conference on 3D Printing to discuss the legal, regulatory, and business issues that arise when products are manufactured using 3D printing or additive manufacturing techniques, rather than traditional manufacturing methods.

During the conference, 3D printing was described as the digital revolution, the fourth industrial revolution, a game-changer, and a disruptive innovation. Although the conference focused on all different types of 3D-printed products and uses, it is safe to say that the printing of medical devices falls under each of these descriptors, and may comprise some of 3D printing’s most innovative uses.

Scientists successfully printed 3D human heart tissue

3D printing to disrupt healthcare

Medical technology continues to advance all the time, with life-saving procedures and medicines that were previously unheard of. Now, Global Data believe that 3D printing could be as disruptive to healthcare as the internet has been to retail.

Article pictureThe company initiated a study for its Disruptor Tech database, and the results revealed that 3D printing could revolutionise the supply chain by limiting the gaps between sourcing, production, and distribution. 3D printing has the ability to create ‘clinical trial ready’ devices without the need for expensive tools, computer-aided manufacturing, and computer numerically controlled manufacturing. As a result of this, price is lowered and waiting times are also reduced.

3D Printing gives rise to external organs

Printing accurate models of organs is reducing recovery time and healthcare costs.

16By taking advantage of 3D printing technology, doctors are presented with tangible, accurate models of organs. This is helping both doctors and students to perform better. Some programs and labs have been started in hospitals to try and adopt 3D printing technology. According to doctors, the program has empowered med students to invent their own solutions to healthcare challenges and helped tighten design cycles. Their products draw from training and experience with actual patients, striving to make a difference in the quality of care for future generations.

The following was derived from an interview from an interview with Todd Pietila, Materialise’s business development manager for hospital 3D printing. He talked about what models are printed, how they help, regulations, and more.

Printing body parts in hospital shows 3D tech’s growing reach

Three-dimensional printers are letting doctors in Minnesota make simulated body parts in a hospital and a Brooklyn startup create rocket engines designed to put satellites into orbit, executives said Thursday at an event hosted by General Electric Co.

The unusual locations for additive printing, highlighted at the first such event GE has organized, showed how quickly the technology is moving beyond plastic prototypes to everyday industrial use.

Companies are now routinely printing titanium engine parts, customizing dashboards of high-end cars, turning out jewelry and eyeglass frames and developing rocket engines.

The Medical Industry and 3D Printing: A Perfect Match

Medical device designers and manufacturers have many special needs that 3D printing can help meet.

3D printing, also known as rapid prototyping and additive manufacturing, is slowly making the leap from a method of making prototypes to one that can also make functional parts. But even in its current state, doctors and biomedical engineers can make good use of 3D printing in a wide variety of links in the medical-device value chain, according to Stratasys, one of the leading manufacturers of 3D printers and a presenter at the MDTX Show.

For medical R&D. 3D printing does live up to its original name of rapid prototyping. It lets biomedical engineers move more quickly from design to physical object and from verification to validation, and then the final design. They can mock up a non-working version to test the fit and form of instruments and implants. In many instances, 3D printing also lets them build functional parts for testing. The prototypes are created quickly compared to previous times when they were hand-crafted by skilled modelers. This speeds up the design phase by letting the engineering team go quickly through several iterations on a design, incrementally improving it or rejecting different approach. Prototypes can also be given to physicians for feedback, and they intuitively understand 3D prototype faster than by trying to understand how a 2D model on a computer screen will look and feel.
