Additive Manufacturing Brings Marusenko Sphere 3D Puzzle to Life

Everyone had a Rubik’s Cube when I was a kid, or least a Rubik’s knock-off. The news ran stories about people who could solve the Cube in under a minute, twisting and spinning the puzzle in their hands, while the rest of us could barely keep the colors in order. I solved the Cube only by taking the entire thing apart and putting it back together. Some kids peeled off the stickers.

I bet old Ernő Rubik (inventor of the Rubik’s Cube, if you hadn’t guessed) would have loved to have additive manufacturing to provide rapid prototyping services for him when he was designing the Cube. The current generation of 3D puzzles, the Marusenko Sphere, was lucky enough to have 3D printing around to assist with the design and prototype phases, greatly simplifying the production process.

EADS, EOS Pair for AM Sustainability Study

Regardless of how promising a new technology appears, most companies are going to want to test its capabilities before deciding to invest. The volume of research data increases every time another company decides to look at the technology, until eventually the technology is deemed right for the job at hand.

Perhaps taking their cue from companies like GE Aviation or Rolls Royce, EADS has paired with EOS to test the sustainability of parts made using additive manufacturing (AM). The results of that study were recently made public with the publication of a case study that pits direct metal laser sintering (DMLS) against rapid investment casting. Continue reading

EOS and 3D Micromac Partner to Form 3D MicroPrint, New Micro Laser Sintering Company

Bigger isn’t always better. While many additive manufacturing (AM) systems seem to be focused on growing larger and larger build envelopes, you don’t always need bigger parts. Micro laser sintering looks to be growing in popularity for the usual reasons AM is popular: speed and freedom of design.

EOS and 3D Micromac are hoping to hit the peak of the micro interest with the formation of a new company dedicated to micro laser sintering named 3D MicroPrint Continue reading

Rapid Ready Roundup: EuroMold Edition

In the course of my diligent efforts to keep you good people up to date on the state of additive manufacturing (AM), I come across many interesting news items. I’ll gather them up every so often and present them in a Rapid Ready Roundup (like this one). You can find the last Roundup here.

Today’s Roundup is focused on the happenings at EuroMold 2013. We already brought you news of 3D systems new product announcements. We’ll start today with some materials news from Stratasys. The company’s newest material is named Nylon 12, and it works in the Fortus line of AM systems. According to Stratasys, Nylon 12 offers up to five times greater resistance to breaking and better impact strength compared to similar materials. Continue reading

EOS Unveils Two New Additive Manufacturing Systems: the EOS P 396 and the EOS M 400

The news just keeps rolling out from Euromold. Additive manufacturing (AM) systems are on the rise, and EOS is adding to the possibilities offered by the technology with the announcement of two new industrial 3D printers. The EOS P 396 works with plastic material, and the EOS M 400 builds in metal.

According to the company, the EOS P 396 offers improvements over older AM systems by increasing material efficiency by up to 30%. Secondary processing times have been reduced thanks to a new point pyrometer and a low wearing, high speed recoater. The new point pyrometer measures the temperature of the powder surface with the intention of improving coating precision. Primary processing times have also been reduced with the introduction of a new, CO2, 70 W laser. Continue reading
