3D printer essential maintenance guide

Teaching Tech shared this video on Youtube!

In my Q&A video I had a request to cover 3D printer maintenance. Prevention is better than cure so I present this guide on items to check and attend to to keep your 3D printer running at its best.

4 Incredible Examples Of 3D Printed Homes

Building a house has always been a time consuming, expensive and labor intensive task. With 3D printing, this traditionally difficult process is changing with the technology now increasing efficiency and lowering costs. In the last few years full scale 3D printed homes, bridges, cabins, and large scale structures have been popping up more and more. These projects present new and unique design concepts and help expand affordable housing. 

3D printing helps make the process much less expensive and time consuming. Because 3D printed structures are relatively quick to produce, this makes them an ideal solution for emergency and low income housing. It also allows for the use of unconventional shapes and textures that would be highly expensive to create otherwise. 3D printing is also more environmentally friendly, as it is possible to print using raw soil and waste from the rice production chain or print using our overabundance of plastic. 

There are many intriguing examples of completed and ongoing 3D printed house projects appearing all over the world. Here are just a few of those.

The Gaia Earth House

In Italy, Crane WASP Technology created Gaia, a house made out of natural materials from the surrounding area. They developed a compound composed of 25% of soil taken from the site (30% clay, 40% silt and 30% sand), 40% from straw chopped rice, 25% rice husk and 10% hydraulic lime to print the house. It has almost no environmental impact and does not need any heating or air conditioning in winter or summer.

The Succulent Ceramic Tiled Shed

After a housing shortage in the San Francisco Bay Area, restrictions on accessory dwellings were loosened allowing people to build extra housing in backyards. A company called Emerging Objects created a 120 square foot 3D printed backyard shed, the front of which is completely covered with 3D printed succulent planters. The roof and the rear and side facades are covered in a 3D printed ceramic screen composed of 4,500 ceramic tiles.

The 45 Day Villa

In China, a company called HuaSheng Tengda printed a 400 square foot villa live and on-site in 45 days. The 250mm thick walls of the villa were printed using 20 tons of C30-grade concrete making it highly durable. It was even found to be able to withstand an earthquake up to a level eight on the Richter Scale after seismic testing.

New Story + ICON’s 3D Printed Community in Tabasco, Mexico

New Story, a non-profit organization building affordable and secure homes for those in need has partnered with Austin, Texas based ICON to create a community of 3D printed homes granted to families in extreme poverty or unsafe shelters. These 500 square foot homes feature 2 bedrooms, a living room, kitchen and bath and were each printed in 24 hours over several days by ICON’s Vulcan II.

These projects illustrate the wide range of possibility that 3D printing offers the architecture world. It shows that it is becoming more and more possible to create secure, environmentally friendly and affordable homes for more people not only expanding design innovation and opportunity but providing relief for those in need.

An Introduction to Oligomers for 3D Printing Inks & Coatings

Oligomers for 3D Printing Inks & CoatingsIn the world of 3D printing, the word photopolymer gets (increasingly) thrown around a lot. But what is a photopolymer, really? Yes, it’s a liquid that’s ‘cured’ into a solid via light, but what makes it do that? Here, we’ll discuss the polymerization process and the two primary ingredients of photopolymers: monomers and oligomers. Additionally, […]

Ford and EOS combat wheel theft with 3D printed lock nuts

Ford Motor Company and EOS are combating alloy wheel theft with unique 3D printed locking wheel nuts designed using a driver’s voice.  A singular soundwave collected from this vocal recording is converted into a 3D printable pattern indented into the nut and key components, which can not be loosened with standard tools. “It’s one of the worst […]

Additive Composite and Add North 3D develop 3D printing filament with neutron shielding capabilities

Swedish 3D printing material developers Additive Composite Uppsala and Add North 3D have collaborated to develop a polymer composite material for radiation shielding applications.  The material, named Addbor N25, is a combination of boron carbide and nylon, and has been developed and produced as filament optimized for 3D printing. The radiation shielding capabilities are provided […]

Delft University of Technology & Maaike Roozenburg 3D Print Chinese Porcelain

China is famous for its blue and white porcelain, delicately and artfully produced and painted. Crafted mainly in the southern Chinese city of Jingdezhen and purchased by travelers visiting the East Asian markets, this porcelain also served as a popular export—from the 1600s on; in fact, up to 35 million pieces may have been exported by the Dutch East India Company.  Now, designer Maaike Roozenburg is working with Delft University of Technology, not only to preserve an important heritage but also to bring forth beautiful 3D samples of originals for everyone to enjoy. A few years ago 3D printing maven Olivier van Herpt developed 3D printing for porcelain and the world’s first porcelain 3D printed pieces can be seen in The Gemeentemuseum in The Hague. Now Maaike and the University of Delft have come up with a way to scan and recreate ancient objects.

“The whole history of porcelain is fascinating,” says Roozenburg. “It’s this magical white material and something they invented in China. There was an obsession with it. Everyone wanted it, and in China, they started to really produce porcelain especially for western markets. All the royals in Europe loved it.”

Artists in the Netherlands were particularly fond of the Chinese porcelain and its classic design, and they created Delftware, an imitation which became its own brand.

“In the 17th century, ceramic Delftware vases decorated the gardens of royal Het Loo Palace in Apeldoorn,” Roozenburg says. “But they are all gone. Archeologists found some bits and pieces, and scientific proof that they were there, together with drawings and paintings.”

“Thank God, at the time, royals gave these vases as presents to other royals!” says Roozenburg, commenting on the fact that only two were found—one in Erddig Hall in the UK, and the other in the museum of Schloss Favorite in Germany.

Unfortunately, administrators would not allow any vases to be taken out of the respective castles, so Roozenburg and his team traveled to them, bearing Artec 3D scanners in their backpacks and overcoming a variety of challenges, including scanning problems due to the reflective nature of the glass (overcome with the performance of the Artec Eva scanner).

The team also made practice vases first, using Styrofoam models to practice on:

“You don’t want any surprises when you’re in a castle in Britain and realize you have to improvise!” said Roozenburg.

“I think what’s amazing about scanning is that, by rendering physical objects that are really fragile, valuable, and have to stay within a museum into digital data, you can experiment with them,” says Roozenburg. “It gives new opportunities to work with historical objects that you otherwise would not be able to touch.”

Because handling of the objects is such a major issue due to worries over disintegration or items being broken, they created a round platform with a small motor—allowing the vase to be rotated and scanned via the Artec Eva, mounted on a tripod. Next, they used the Artec Space Spider for detailed ornamental parts like lions heads and shells. Once scanned, files were processed in MATLB and then 3D printed.

“The best thing is, in the end you can’t see that there was any new tech used. The finished work of 45 vases look like the originals, like they are brand new coming from the oven in the 17th century,” says Roozenburg.

With 3D scanning, users around the world are able to enjoy the benefit of making parts that need to be replaced, or that in some cases have become obsolete; here, everyone involved in the project is able to work with pieces that are hundreds of years old—and able to be handled without worry once they are transformed into 3D form.

“It’s culture,” says Technical University scanning expert Naagen. “We should make it accessible to people all over the world.”

Scanning equipment from Artec3D has been behind some of the most exciting projects involving artifacts over the past few years, involving archiving work with museums, preserving the first World War 1 monument, and much more.
