3D PRINTING RESEARCH

Concrete as a material

The Philippines’ Lewis Grand Hotel is home to the world’s first-ever operational commercial structure created using 3D-concrete printing technology by Andrey Rudenko and his team. The 3D-Printed hotel suite measures 10.5 meters by 12.5 meters with a height of 4 meters, and includes two bedrooms, a living room, and a Jacuzzi room with a giant 3D-Printed Jacuzzi.  Printing was completed on September 20th, 2015.

The same designer built a 3d printed castle in his backyard. It measures 3m by 5m.

Material options ( opaque and solid)

  • Brass
  • Colorful Sandstone
  • Porcelain
  • ABS Plastic

BRASS:

Polished Brass goes through extensive hand polishing to give it a smooth, shiny finish. It is perfect for jewelry and precious products.

Raw Brass has a rustic matte look, with rough surfaces and some tarnishing (color spots). It is great for antique-looking objects, functional parts, jewelry prototypes, and metal models that you’d like to polish and finish yourself.

Shapeways’ Brass consists of 15% zinc, 5% tin, and 80% copper.

PORCELAIN:

Cleaning excess powder from the 3D printed molds is our biggest limitation in manufacturing porcelain. The mold is an inverse of the product itself, where solids of the product are empty space. Laser sintering the mold leaves its interior full of loose powder. We carefully blow it out with compressed air through the flat base of the model, but tight cavities far from the base opening are hard or impossible to clean. This means that models which are complex and have multiple holes in walls or long wires become increasingly hard to print. If you need to troubleshoot, try making the model solid and based on a single “core”.

Because of the molding process, some surfaces may contain seam lines and marks from the funnel. We do our best to repair the surface of the model but because this is done manually there may be some trace memory of these marks left on the surface.

COLORED SANDSTONE:

Sandstone is the only material capable of full-color 3D prints. Produced on Z-Corp printers, it is perfect for figurines, life-like models, avatars, and other products that lend themselves to colorful, high-quality printing. Models are created by printing binder material and colored ink layer-by-layer into a bed of gypsum-based powder. After printing, the models are finished with a cyanoacrylate (super glue) sealant to ensure durability and vivid colors. The final product is a hard, brittle material that works great for figurines and visual models, but isn’t well suited to functional parts or daily handing. Models should be handled carefully, and not exposed to water as it will cause fading.
