NASA has announced plans to launch in 2018 the Refabricator, a large recycling and remanufacturing machine intended to shred plastics and metals into reusable material and then use the material to 3D-print new objects — all of this done within the same device.

The Refabricator project is the responsibility of Tethers Unlimited, a space tech firm based in Seattle, Washington Tethers Unlimited received $750,000 in award money from NASA to fund the program. Plans are now in place to have the Refabricator installed into the International Space Station (ISS) by next year.

The Refaabricator project is similar in function to other recycling innovations being sought around the world. 3Devo, from The Netherlands, is one such country pursuing recycling plastics with their SHR3D IT system for shredding and granulating plastics for reuse. The Precious Plastics project, the brainchild of Dave Hakkens, is another such foray into creating localized recycling systems for plastics. Precious Plastics is also being conducted as an open-source operation with free downloads of equipment plans and installation instructions.

Rob Hoyt, CEO of Tethers, commented on the Refabricator project for NASA by saying, “The Refabricator demonstration is a key advance toward our vision of implementing a truly sustainable, in-space manufacturing ecosystem. Astronauts could use this technology to manufacture and recycle food-safe utensils, and turn what is now inconvenient waste into feedstock to help build the next generation of space systems.”

XYZPrinting announces launch of color FDM printing

Taiwanese 3D printer manufacturer XYZ printing, said to be largest seller of 3D printers, has launched a model that produces FDM PLA spool-fed prints in full color with a range of 16 million colors. The Da Vinci Color model printer, which sells for $2,999.95, is looking at a significant section of the market share of schools and small businesses looking to print durable objects in color.

The device is being launched at Berlin’s IFA 2017 show this week, and hopefully more will be revealed on how coloring is applied to digital files prior to printing. The samples being promoted now show a range of colors and coloring intricacy. If everything XYZPrinting says is true, the printer stands to be a game-changer for 3D service bureaus and start-ups alike.

XYZ launches full color FDM printing

Color is achieved by use of inkjet cartridges applying color between layers

The process is a simple one in terms of innovation. The Da Vinci Color is a standard FDM printer that uses ordinary 2D color printing cartridges to deliver color between the layers of polylactic acid (PLA) plastic.

Simon Shen, CEO of XYZprinting comments, “With its 3DColorJet technology, the da Vinci Color is a breakthrough in 3D printing technology as it provides full color spectrum accuracy at an afford able, small business-friendly price, that is unmatched by any other color 3D printer in the market.”

The Daily 3D Detail: Key development made in 3D-printing copper

Key development made in 3D-printing copper

The selective laser melting (SLM) method of 3D-printing is effective for most metals and many alloys, with the unusual exception for pure copper. While copper alloys have been used in the past, using SLM for copper has failed to the high degree of reflection affecting the laser attempts.

A new development being announced at the formnext 2017 trade show in Frankfurt, Germany by Fraunhofer Institute for Laser Technology ILT has changed that outlook. The research project, funded by AiF German Federation of Industrial Research Associations, indicates that by using laser light in the green spectrum range, in the 515 nanometer wavelength, the absorptivity grows, thereby requiring less power needed to achieve consistent melting results.

Because pure copper is more electrically and thermally conductive than most metals and alloys, the need for pure copper parts is substantial and proves to a lucrative aspect of 3D-printing. But copper reflects up to 90% of laser radiation, so only a small amount of the energy is received by the material. Also machine components can be damaged by the reflected radiation, and when the copper transitions to a liquid state, it results in an unstable remelting process.

“We are hoping for a more homogeneous melt pool dynamics so that we can build components with high material density and achieve other positive effects, such as a higher detail resolution,” said Daniel Heussen, a Rapid Manufacturing group research fellow, of the new SLM approach.

Fraunhofer ILT is building its own green laser source as a result of the studies. The project is referred to as “SLM in green,” the goal of which is to produce a laser with an output of 400 watts in the green light wavelength (515 nm). If successful, devices will be able to 3D-print intricate objects in pure copper, which will be a boon for the construction of electrical components.

Competition for NASA’s 3D Printed Habitat Challenge was held at Caterpillar’s Edwards Demonstration and Learning Center in Peoria, Illinois

Referred to as NASA’s 3D Printed Habitat Challenge, the competition has elicited the efforts of five separate teams attempting to best each other in the ever-increasingly more difficult requests. Cash prizes have been given out to the top three contenders in each level of each phase. In the three levels of Phase Two, Branch Technology and Foster + Partners were in the top three of each event. They garnered top prize in level one, a challenge of printing a cone and a cylinder subject to endurance testing; third prize in level two involving the 3D-printing of a support beam (top prize went to South Korea’s Team Moon X); and now the top prize in 3D-printing a dome structure holding 3,726 pounds of ultimate load.

These challenges have brought space structures closer to a viable reality, admits NASA’s Deputy Associate Administrator for Space Technology Mission Directorate Jim Reuter. “The advancement and innovation in additive construction that we’ve seen from these teams is inspiring,” said Reuter. “Meeting the technology goals of this challenge proves that competition can push boundaries, and their work puts us that much closer to preparing the way for deep space exploration.”

Branch Technology and Foster + Partners also credited Techmer Polymer Modifiers for their work in material support.

The Daily 3D Detail: 3D-printing giant LEGO blocks

Posted by Editor On August - 27 - 2017Comments Off on The Daily 3D Detail: 3D-printing giant LEGO blocks

3D-printing giant LEGO blocks

As many parents of young children understand, the commodities markets (gold, silver, pork bellies) shamefully neglect to catalog the ongoing rate of one of the world’s most collectible items: LEGO blocks.

As LEGO blocks continue to hold their dollar value over time, the prospect of 3D-printing them grows. LEGO blocks are originally made of ABS (acrylonitrile butadiene styrene) and can be easily duplicated by most 3D printers. STL (stereolithography) files for LEGO block downloads have been around for years.

As the “world’s most powerful brand” LEGO has a strong tradition based on a singly mindful element of their product. It’s virtually impossible to replicate precisely. Even asian knock-off brands of LEGO blocks fail miserably across the board in terms of ease of use and reliability. And forget about having them work together with true LEGOs.

In terms of legal precedent in the LEGO trademark, a number of companies have been sued for infringing upon the LEGO design of their interlocking blocks. LEGO patented their definitive shape of the bricks with their inner tubes in 1958, but the latest European Court of Justice ruling in 2010, stated the eight-peg design of the original Lego brick “merely performs a technical function [and] cannot be registered as a trademark.”

Knock-off companies like Wise Hawk are shameless in their marketing and produce inferior products

So printing one’s own blocks are likely to run into the same quality control issues that plague all other attempts at replicating LEGOs accurately. But printing them at five times the size? That’s a different animal altogether.

Mantis, a two-ton hexapod built by Matt Denton

Meet Matt Denton. Denton’s claim to fame is being the creator of the six-legged two-ton human-scale hexapod called Mantis. His latest contribution to the world is his giant-sized LEGO block creation, a five-times scale model of a LEGO go-cart, model no. 1972. Designed as a LEGO kit in 1985, this buggy cart with dual wheels and working rack-and-pinion steering took 168 hours to make — approximately seven days of printing. The end result weighed 5.1 kilos and cost a little over £100.

In his video series in two parts on the 3D printing of the blocks, Denton explains his tricks of the trade to replicate the LEGO creation in its massive size off a Lulzbot Taz 5 printer. Using extensive brimming to minimize warping at the edges, and foregoing support material in key spots were some of the techniques Denton employed. The video is extensive in construction detail, explaining which parts should be built in sections. No doubt this will not be the first of these mega-size LEGO creations, as anyone with a 3D printer can follow Denton’s lead through his step-by-step instructions.

It’s only a matter of time now until giant LEGO blocks becomes its own sub-Reddit thread. In the meantime, investing in LEGOs still proves to be a viable retirement plan for most parents.

The Minion chess set is sure to please young players

We love All3DP.com and their extensive lists. Known for ranking printers or presenting DIY projects, All3DP.com has been a favorite website of printrs for years.

Their most recent list is a celebration of 3D-printed chess sets and the selection is impressive. Whether you prefer conventional designs or unique assortments of chess pieces, this list is well-worth a scrolling and bookmark.

Our new favorite STL download

The takeaway from this list is it is inevitably incomplete. Chess sets are a popular choice for beginner printrs and modelrs and there is no limit to the imagination that can occupy 16 squares on a chess board. Hopefully exposure of this list will generate even more download options and more follow-up lists to come.

Once you’ve downloaded and printed your set, you may consider traipsing over Chess.com and playing the built-in AI interface. Ranked from levels 1 through 10, the AI is ready to match you at your skill sets and challenge you appropriately. Most can handle levels 3 and 4, whereas grandmasters find themselves stumped by level 8. No one, apparently, is smart enough to beat the computer at level 10.

In addition to gaming, the Chess.com site also offers tips and strategies and a variety of resources for chess enthusiasts.

The Daily 3D Detail: Urine in Space

Posted by Editor On August - 25 - 2017Comments Off on The Daily 3D Detail: Urine in Space

Researchers provide possibility of printing 3D objects by harvesting astronaut urine

Urine in space may be used to create 3D printing inks

Researchers from the Blenner Research Group of South Carolina’s Clemson University have introduced a novel way of creating 3D printing ink in space from human urine. The discovery, a process of harvesting yeast bacteria that feed on the urea present in human urine, may be the answer for providing raw materials for use in constructing objects in space.

Bear Grylls understands the value of urine in unforgiving environments

The Blenner Research Group presented their results today at the 254th National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world’s largest scientific society, featured nearly 9,400 presentations this week in Washington, D.C. on a wide range of science topics. Of these presentations, the prospect of harvesting construction material from urine garnered worldwide attention.

“If astronauts are going to make journeys that span several years, we’ll need to find a way to reuse and recycle everything they bring with them,” says Mark A. Blenner, assistant chemical and biomolecular engineering professor at Clemson University.

Urine in space may be used to create 3D printing inks

The process requires gene splitting and the use of the yeast called Yarrowia lipolytica. By employing CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology to the yeast DNA, the researchers believe they will be able to convert the hydrogen and carbon molecules, which result as fatty acids and are seen as beginning molecular building blocks, into constructible material. The research, funded by NASA’s Space Tech Research Grants, is looking at editing the DNA so that the yeast are able to produce polyester globules instead of the fatty acids.
