🤩 Hobbyist 3D Printing

YouTube Recently Updated Content Policy Around Gun Content, Including 3D Printed Guns (3 minute read) - Link

YouTube is introducing new restrictions on gun-related content:

• Videos selling guns or showing 3D-printed gun assembly will be age-restricted (18+).

• Instructions on removing gun safety features and videos of automatic weapons will also be age-restricted.

• Artistic gun representations and public interest videos (news, military footage) are exempt.

3D-printed gun makers are unhappy about the changes. They argue their audience is mostly adults and that age-restricting their content hurts their channels due to how the algorithm surfaces their videos to people with or without accounts. They also find it illogical for news footage of war to be accessible to young viewers while their content is restricted.

YouTube says the policy update reflects the rapid advancements in 3D printing technology.

PrusaSlicer 2.7.5-rc1 Released - Link

The first release candidate for PrusaSlicer 2.7.5 was released on Friday, mainly focused on compatibility with new features in Prusa SLA printer firmware 1.8.0. Below is a summary of the changes introduced:

Sintavia Develops New 3D Printing Processes for Hypersonic Engines (4 minute read) - Link

The US Department of Defense tapped Sintavia to develop 3D printing methods for crucial components in hypersonic propulsion systems. This project focuses on validating 3D printing for hypersonic parts, establishing industry standards,and simplifying manufacturing by reducing the number of parts needed. Additionally, it aims to open doors for small businesses to participate in hypersonic production.

This contract aligns with the DoD's broader GAMMA-H initiative to discover new manufacturing techniques for hypersonic weapons. It follows a similar project awarded to Aerojet Rocketdyne for creating a 3D-printed hypersonic propulsion system prototype.

Restor3d Snags $70 Million in Funding Round - Link

Restor3d, a leader in 3D-printed personalized orthopedic implants, has secured $70 million in funding. This investment will fuel their mission to transform orthopedic care.

The funding will focus on several key areas. First, restor3d will develop new patient-specific implant systems for ankles and shoulders, expanding their existing offerings for hips and knees. They'll also develop a 3D-printed porous press-fit knee implant for their existing portfolio.

Secondly, restor3d will invest in faster 3D printing technology to streamline production and reduce costs and delivery times for these personalized implants. Additionally, they'll invest in software and design automation to expedite case intake, design processes, and overall service for surgeons and patients.

Finally, restor3d plans to expand their educational initiatives, providing surgeons and sales teams with in-depth training on the latest technologies and surgical techniques in orthopedic and reconstructive surgery.
