3D printing scalability: more than a hardware problem (Authentise Weekly News-In-Review – #114)

One of the major hindrances to 3D printing’s expansion right now is scalability. How can a process tailored and designed for customization also be an ideal candidate for the highly systematized environment of a production facility? How can it be employed to retain its features like agility and flexibility while providing the level of performance required to make a business profitable? The answer is multifaceted, and it has to do with the technology itself as well as the infrastructure that we build around it. Researchers are working towards designing printing techniques that are both reliable and efficient at various scales, and significant strides have been made in that regard. In parallel, one must consider the surrounding pieces of this puzzle, such as an automated pipeline and a smart, data-driven decision-making platform. It just cannot work if you couple 3D printing technologies with the old way of making factories work. In many respects, we must rely on AIs and robotic systems to make informed decisions. We are already starting to make this vision come to life, with IIoT networks feeding into simulations and triggering automated processes. Authentise is the leader in data-driven automation for production scale 3D printing: we already use machine learning algorithms to drive our estimation processes and thorough automation features throughout our 3Diax platform, and are excited to show you more of what we are working on very soon!

Israeli company announces tiny triumph in micron-level 3D printing

Nanofabrica micron-level 3D-printed part

Startup Nanofabrica (Tel Aviv) announced that it has developed an AM platform that provides an end-to-end bespoke process for manufacturers seeking micron and sub-micron levels of resolution and surface finish. Nanofabrica’s AM process is based on digital light processing (DLP), which is combined with adaptive optics to achieve repeatable micron levels of resolution. This tool in conjunction with an array of sensors allows for a closed feedback loop.

Scalable platform 3D prints bone

3D printed construct

Researchers from Syracuse University have achieved significant progress towards the engineering of large-scale bone tissue scaffolds. Stephen Sawyer and colleagues have designed, built and tested a scalable platform for the structured growth of bone mineral using only a commercially available 3D printer and inexpensive materials. The design surpassed previous difficulties associated with the supply of oxygen to bone growing cells. Traditional designs relied on oxygen diffusion through the cell containing structure, which had, until now, limited the size of bone structures that could be built.

Brain code can now be copied for AI, robots, say researchers

Modeling robotics on the human brain

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), the University of Cambridge, Japan’s National Institute for Information and Communications Technology (NICT), and Google DeepMind have argued that our understanding of how humans make intelligent decisions has now reached a critical point. Robot intelligence can be significantly enhanced by mimicking strategies that the human brain uses when we make decisions in our everyday lives, they said.

Redifining Medical Customizability (Authentise Weekly News-In-Review – Week 07)

Hi all and welcome to week 6 of Authentise News-In-Review!

This week we are going to talk about customization for medical applications. AM’s freedom of design makes this one of technology’s core benefits, but nowhere is this more true than in the medical arena. We’ve long heard about custom prosthetics but it can go much further than that. Personalized medicine is taking giant steps to practicality thanks to AM and new “bioinks” are enabling new treatments that could mould to specific patients’ scenarios, like dodging intolerances or adding particular vitamin supplements. Laboratories can study diseases in custom made samples thanks to 3D printing’s power to change design, physical properties and materials on the designer’s whim.

Let’s dive in.

A new 3D bioink for PolyJet 3D printed pills

Researchers at the University of California in Los Angeles (UCLA) have developed a viable bioink for 3D printed pills.  In this study, Giovanny Acosta-Vélez, Chase Linsley, Madison Craig and Benjamin Wu favour the inkjet technique over other 3D printing technologies for its speed and ability to print at room temperature. The temperate environment ensures that active pharmaceutical ingredients (APIs) aren’t damaged in the process, and speed is of course preferable for mass production. The 3D printable bioink from UCL is made from hyaluronic acid – a key ingredient in skin, connective tissues and the nervous system. A photoinitator is added to the acid so that it solidifies when in contact with light. This mixture is used to fill preformed tablets displaying the properties of an atypical oral tablet.

Porous 3D printed scaffolds help Rice University scientists tackle bone cancer

Scientists at Rice University in Houston have used 3D printing to create porous, bone-like scaffolds that can be used to study bone cancer tumors. They found that the size and orientation of individual pores affected how cells proliferate in the absence of blood. According to bioengineer Antonios Mikos, the 3D printed polymer bone scaffold contains artificial pores that constrain the flow of fluid and apply shear stress to tumor cells […] The scientists believe that this model could be vital for finding out more about bone cancer and potential treatments: “We aim to develop tumor models that can capture the complexity of tumors in vitro and can be used for drug testing, thus providing a platform for drug development while reducing the associated cost,” Mikos said.

3D Printing the Future of Surgery

One of the most hotly anticipated areas for 3D printing to impact is medicine. A myriad of stories have appeared pointing to all manner of exciting innovations in the medical field. Sadly many of the “3D printed ear/nose/heart/ etc.” stories have been rather disingenuous or are at the very least very optimistic. To give you a more accurate view of the possibilities of 3D printing in medicine we’ll look at one particular area: surgery.
