What is the future of AM going to look like? (Authentise Weekly News-In-Review – #106)

With AM, as with any other exponential technologies, it’s very hard to make a sound prediction on its future development, even in the next 5 years. However, there are clear indications that certain roadblocks will most likely be surpassed. Industrial settings will see reliable and large-scale AM technologies being pushed to the high standards required to being widely adopted. New materials with exciting properties will enable new, unthought of applications and provide sustainable new ways to drive AM production forward. All the while, new engines with record number of AM parts will keep being produced and new crucial precedents will be set for future developments to build upon.

HUST Researchers Iron Out Cracks Of 3D Printed Bulk Metallic Glass

A team of researchers led by Professor Ning Li at the Huazhong University of Science and Technology (HUST), China, have discovered a way to scale-up 3D printing of bulk metallic glass (BMG). With a unique atomic structure, BMG alloys are highly resistant to wear and corrosion while maintaining the melted malleability of glass. However, micro-cracks that occur during 3D printing present a severe disadvantage to BMG utility. At HUST, Professor Li, Jianji Zhang, Wei Xing, Di Ouyang and Lin Liu have developed composite iron and iron-nickle BMG alloys that suppress these deal-breaking micro-cracks, with findings that provide general guidelines for processing BMGs via selective laser melting (SLM).

A group at the Swiss Federal Laboratories for Materials Science and Technology, Empa, is investigating ways to 3D print cellulose. As the most abundant organic polymer in the world, the material is sustainable, and biocompatible, presenting great potential for medical research. Recent progress made at Empa demonstrates how to 3D print cellulose nanocrystals (CNCs) as a material reinforcement. Experimentation also shows how to tune the orientations of these CNC “building blocks” to achieve different properties in a finished object.

Why manufacturing agility is the real game changer (Authentise Weekly News-In-Review – Week 87)

AM is being touted as the next manufacturing revolution, but all things considered, it’s just another tool on the belt. What’s really exciting is the paradigm that AM, alongside other technologies, bring to the board: true manufacturing agility. The ability to react to new or changing requirements on the fly, not being constrained by location or methodology. This means having adaptive factories, with tools that bridge and compensate the lackings of each other. Metal casting is still very much being used and will be for quite some time. This transformation is being fueled by the digital thread that permeated the manufacturing industry. Cloud-based platforms and modular designs, both in terms of hardware like the MachineBuilder or software like our very own 3Diax solution, offer unparalleled flexibility and efficiency to the user. These technologies enable problem-solving to be taken to a whole new level, decentralizing production capabilities yet interweaving a smart network of data and manufacturing hotspots.

The Battle of innovation and tradition: Metal Casting vs Metal 3D printing

Additive Manufacturing is very often referred to as the new industrial revolution. From 3D printed car parts to airplanes or houses, 3D printing is changing the world around us. But how does the innovative and fairly young technology perform compared to classical Metal Casting which has been used for centuries?

Meet 3D MachineBuilder, a Web-Based Platform for speeding up Custom Machine Design

Canadian company Vention is offering a solution in 3D MachineBuilder. This cloud-based design and build system brings hardware and software together into the same digital workflow, potentially speeding the development time of custom industrial equipment and prototyping by five times over.

The company’s public assembly library offers hundreds of open-source designs created by the company’s engineering team as well as current users. According to CEO and founder Etienne Lacroix, Vention is different because it’s the first digital manufacturing platform dedicated to machine design.

U.S. Marines 3D Print F-35 Part To Save $70,000

A team of U.S. Marines 3D printed a part for the F-35 stealth fighter saving $70,000 in costs for a whole new landing gear door.

The component is a small part mounted on the door pressing it into the latch. It was designed and 3D printed by Marines from Combat Logistics Battalion 31 (CLB-31) in Carderock, Maryland.

Sam Pratt, a mechanical engineer at the Carderock’s Additive Manufacturing Project Office, provided further technical assistance to the team.

“YOU CAN’T BUY THE PIECE SEPARATE FROM THE LANDING GEAR DOOR WHICH IS A COST OF $70,000. BY HAVING THE CAPABILITIES TO PRINT IN THE FIELD, WE WERE ABLE TO REPLICATE THE PART FOR A COST OF ROUGHLY 9 CENTS.”
