S-Max  is a large volume sand casting 3D printer by ExOne used to additively manufacture molds needed for industrial metal casting. This machine does not print directly in metal but makes casts and cores to pour in molten metal by jet binding fine powder. It works similary to your desktop inkjet paper printer but it applies special Furan resin binder to layers of silica sand, cerabeads or zirconia which are "glued" together making a solid 3D cast. Since there is no heat transfer issues, laser … [Read more...]

This 3D Printed Column Can Withstand an Earthquake

A California-based company claims it created a column that can withstand an earthquake without being damaged. The company, called Emerging Objects used 3D printing technology to create this pillar, and the structure is the essence of its strength. The pillar was 3D printed in different parts, and each part is hollow, therefore creating a high strength-to-weight ratio. Creating an object that was earthquare-resistant was not the initial plan of the team, but they found out that the column … [Read more...]

ESA Works on a 3D Printed Lunar Base

The European Space Agency (ESA) and London-based architectural firm Foster+Partners are working on a way to 3D print a lunar base. For this project they will be using local soil - regolith - instead of plastics, in order to reduce the amount of brought materials and lower the overall costs. The idea is to create a weight-bearing dome with cellular structured walls to provide for shelter against micrometeoroids and space radiation. The base needs to be sufficient to take in up to four … [Read more...]

The Story of Enrico Dini – The Man Who Prints Houses


I came across this interesting interview from the Dutch technology magazine 'De Ingenieur' with Enrico Dini and translated it for you to read.   He was the first to built a working 3D printer for printing buildings and became world famous as "The Man Who Prints Houses'. Enrico Dini had the brilliant idea of producing ​​layered art structures and parts of buildings but the development of his machine and promotion of his ideas cost him his private life. Yet he pushed on through. For … [Read more...]

What? Can you print ice tea?

Ice Tea

Some new crazy materials have entered the 3D printing world recently. The most bizarre one has to be ice tea. Open3DP, a site sponsored by the Solheim Additive Manufacturing Laboratory out of the University of Washington’s Mechanical Engineering Department has been experimenting with all sorts of materials. Now, they finally have a recipe for printed Ice tea (after some extensive research..). There’s only one downside, binders make it inedible… The real purpose of this invention has yet to be … [Read more...]
