Starting this week, we’re shaking things up a little! We’ll be combining our 3D Printing News Briefs with a more curated weekly list of 3D printing webinars and events to make everything more streamlined and efficient.This weekend, we’re covering sustainable materials and scientific research, and events in the medical and space sectors, as well as an ASTM workshop, a 3D Systems webinar about semiconductors, and more.Read on for all the details! 3D Printing News Briefs EOS Aluminum AlSi10Mg Produced with 100% Recycled Feedstock Demonstration bracket made with EOS AlSi10Mg Global additive manufacturing leader EOS recently made an exciting announcement: one of its most popular metal materials, EOS Aluminium AlSi10Mg, is now made with 100% recycled feedstock – an achievement the company says is an AM industry first.
The material was added to EOS’s Responsible Products portfolio a year ago, when it started using 30% recycled feedstock and gained a 20% reduction in CO2e (carbon dioxide equivalent).EOS says that by increasing the recycled content to 100%, it’s been able to achieve 77% CO2e reduction from the prior material, and 83% CO2e reduction in comparison to AlSi10Mg made with virgin raw material.The updated EOS Aluminum AlSi10Mg offers the same characteristics, properties, and performance in 3D printed parts, like 5% elongation at break and 245 MPa yield strength, so customers won’t need to re-qualify their applications.
EOS has several other Responsible Products, including PA 1101 ClimateNeutral polymer materials, as well as the VIRTUCYCLE Used Polymer Material Take-Back Program.“We’re proud to have developed our first EOS metal material made with 100% recycled feedstock and to have achieved so much in less than a year.We will continue to explore ways to reduce the carbon footprint of our customers‘ applications with every EOS product – from materials and hardware to design optimization – they all add up to a more responsible end-use product for our customers and the climate,” said Sophia Heyl, EOS Product Specialist.
3D Printed Mycelium Biocomposites Research The mycelium biocomposite paste, primarily composed of coffee grounds, can be 3D printed using a hobbyist 3D printer, and serves as the substrate for mycelium growth.Over time, mycelium colonizes the printed structure, bridging small gaps it encounters.This capability enables the creation of intricate geometries, including tall vases with delicate, thin walls.
Credit: Danli Luo, Junchao Yang, and Nadya Peek Speaking of sustainability, a study by a trio of researchers at the University of Washington explains how they transformed recycled coffee grounds into living biocomposites with 3D printing.Danli Luo, Junchao Yang, and Nadya Peek built a custom, open source 3D printing system called Fungibot, made entirely from off-the-shelf components so as to be more accessible and cost-effective.Their unique biopaste, called Mycofluid, is mostly made up of used espresso coffee grounds, mixed with brown rice flour for essential carbohydrates.
Grain spawn inoculates the substrate, while a small amount of xanthan gum ensures that the Mycofluid develops a consistent viscosity so it can be extruded.Finally, water is gradually added to perfectly tune the paste for printing.By combining digital fabrication with natural growth of fungal mycelium, the team’s method creates a strong material for printing compostable products, without having to use petroleum-based plastics.
As for the open source printer, a clear polycarbonate tube is used as a material reservoir for up to one liter of Mycofluid.Then, a printhead with an auger-driven mechanism precisely extrudes the paste in a consistent, steady flow.Once the structure is printed, it’s put in a sanitized environment, and gets a daily misting of water over ten days.
During this period, the living fungal mycelium starts to colonize the 3D printed substrate, fusing the layers and forming a continuous, natural “skin” over it.The final structure has some excellent properties: it’s water-repellant, and while the tensile strength decreases a little, its ductility increases, along with its ability to absorb compressive forces.The living mycelium is also able to bio-weld separate printed parts together, as evidenced by the above images of a vase printed in three segments that later merged into one.
This shows the potential for constructing complex, self-supporting geometries that conventional molding techniques can’t always manage.3D Printed Models for HSV Treatment A schematic illustrating the process of using a 3D bioprinter to generate human skin equivalents, and the two models of HSV infection used by the researchers.Image by Dr.
Tori Ellison.About two-thirds of the global population are affected by the Herpes Simplex Virus (HSV), and while many are asymptomatic, other people unfortunately deal with painful flare-ups.Antiviral medications can lower the severity and frequency of these, but it’s not a cure, and their effectiveness may even diminish over time.
These antivirals, developed with simplified cell cultures, aren’t able to replicate the complexity of human tissue, so they have a hard time addressing how the virus behaves in the human body.But, a team of researchers from the Fred Hutch Vaccine and Infectious Disease Division and the National Center for Advancing Translational Sciences (NCATS) created 3D bioprinted models of human skin as a more precise approach to HSV drug development.By depositing fibroblasts into culture vessels, layering keratinocytes on top, and incubating the cells in different media formulations, they developed two organoid models for different HSV infection stages that replicate both the dermal and epidermal tissues in human skin.
The submerged model simulates an initial infection through a break in the skin, while the air-liquid interface (ALI) model mimics the flare-ups that occur from latent virus reservoirs in the body.The team used the 3D bioprinted models to screen a total of 738 medicinal compounds, including both FDA-approved and novel drugs.One of these drugs was acyclovir, which is the current standard of care for HSV.
A recombinant HSV expressed a green fluorescent protein, while fibroblasts were labeled with a red fluorescent protein, so the researchers could examine the direct effect of the drugs on the virus through high-content fluorescent microscopy; if the green HSV signal was reduced, the treatment was working.They determined that, in comparison to the ALI model, acyclovir was less effective in the submerged model, in which HSV infects mainly keratinocytes.This explains why the drug has is so inconsistent in treating flare-ups: it might not be potent enough to control the virus in keratinocytes.
The researchers identified nearly 20 other antiviral compounds with positive results that could help better suppress HSV infections, while causing minimal toxicity to the surrounding cells.3D Printing Webinars & Events March 10 – 14: AAOS Annual Meeting From March 10-14 in San Diego, California, the 2025 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) will take place.The educational program will include workshops, courses, and interactive lectures focused on the latest orthopaedic breakthroughs across all specialties.
