Small scale printing poised to make a big impact (Authentise Weekly News-In-Review – Week 102)

3D printing is usually making the news for big plane components or successful rocket tests. Unsurprisingly, there’s a world of small applications in which the technology can, and is, making an impact. Typical subtractive methodologies are pretty limited at the micro level: 3D printing brings customization and extremely high-precision to labs all over the world. Micro-scale printing is on the table mainly thanks to advancements in material sciences, with polymerization and astonishing “implosion fabrication” techniques. Still, it never hurts to have a hand from biological agents who can do the job for you and when it comes to bio-printing, it’s the way to go to obtain functional, “living” materials.

Microlight3D Offers a New Kind of Microscale 3D Printing

For 15 years, Patrice Baldeck and Michel Bouriau led intense research and development at the Université Grenoble Alpes. They were working on a two-photon polymerization 3D printing process that would become the basis of Microlight3D, founded in 2016. The process would be the first-ever non-additive two-photon polymerization direct laser writing technology. The benefits of the technology are many. It produces extremely high resolution and smooth surface finish comparable to injection molding. It also offers a great deal of design flexibility and eliminates the need for post-processing. It’s a fast technology that produces robust parts in any shape – 100 times smaller than a strand of hair.

New Shrinking 3D Printer

The idea behind the shrinking 3D printer is to print an object and then shrink it to the required size – a technique known as implosion fabrication. The most amazing part about this 3D printer is that it can be adapted to work with different materials like metals, quantum dots and even DNA. Additionally, complicated shapes like microscopic linked chains can be printed too. In multiple tests, the team found that they could shrink a structure by about 8000 times.

Creating Living Materials Using Bacteria and 3D Printing

In a paper entitled “Programmable and printable Bacillus subtilis biofilms as engineered living materials,” a team of researchers discusses how they used 3D printing to produce custom nanoscale biomaterials from the natural secretion of amyloid fibers from the bacteria Bacillus subtilis. The bacteria generate biofilms by secreting amyloid fibers via a tightly controlled cluster of genes called the tapA-sipW-tasA operon. The researchers were able to genetically modify the TasA protein and introduce functional chemical groups onto the TasA fibers excreted by the bacteria. This means that the bacterial films could be designed to act as functional living materials.

Formnext showed us how the AM industry is maturing (Authentise Weekly News-In-Review – Week 98)

The Authentise team has been exhibiting at Formnext in Frankfurt this past week. We had a blast exchanging views on the AM world and better understanding the industry as a whole. In the times between meetings and booth chats, we had the chance to roam the halls and take a peek at what’s on the horizon. What’s been consistently shown is a maturity and wide-ranging offering of products and services. The AM industry is cementing its stance, partly thanks to proven applications and no lack of R&D investment. As we saw it, Formnext was a chance for progress, not groundbreaking. This is not to say that there wasn’t innovation to be found within its halls, on the contrary. But the players are now pushing for market permeation more than ever.

EOS TO PREMIERE MILLION-LASER POLYMER 3D PRINTING AT FORMNEXT 2018

Leading 3D printer manufacturer and service provider EOS, is to debut a new polymer 3D printing technology at Formnext 2018 in Frankfurt next week. This technology, which is reportedly capable of replacing “injection molding in many contexts,” will be presented alongside a demo of Richard Browning’s 3D printed jetpack, and the company’s new quad laser EOS M 300-4 metal system as a production cell. The new developments from the company are made to increase 3D printer outputs to an industrially-competitive scale, a key theme throughout the industry as we saw at last year’s Formnext, and a chief preoccupation for EOS and its partners.

FIT AG presents ‘Spare Parts on Demand’ additive manufacturing solution at Formnext

SPOD FIT AG

FIT AG has presented its ‘Spare Parts on Demand’ (SPOD) solution at Formnext which employs additive manufacturing to produce industrial replacement components. As most parts that need replacing have been made with traditional methods, they have often passed through an approval process, meaning it isn’t possible to create a 3D printed copy. Deutsche Bahn, a German railway company, encountered this problem when attempting to replace the left sandbox housing in a brake system. The component had been manufactured in cast grey iron, and so the part had to be redesigned and then printed in titanium using EBM. The printed part has so far passed on all tests performed. At Formnext, FIT AG has showcased SPOD as a way for this success to be achieved with more regularity.

nanoscribe microscale

Nanoscribe, a specialist in microscale additive manufacturing, was recently selected as the first place winner of the Baden-Württemberg State Prize for Young Companies. The award, worth €40,000, is bestowed upon companies that demonstrate economic success and make a sustainable contribution to society in some way. This week, Nanoscribe has been showcasing its technology at Formnext in Frankfurt. There, the company is exhibiting the fabrication of structures with micrometer precision in millimeter dimensions for the first time.
