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...]

Russian Company Prints a Thyroid Gland to Transplant on Living Rats

t31

This month, a company based in Russia called “3D Bio printing Solutions” became the first in the world to 3d print a thyroid gland for an animal with their own patented bio printing technology. The company’s focus is set to transplant the 3d printed thyroid gland to living rats suffering from a disease called “Hypothyroidism”, a medical condition caused by an overload of iodine in the body. 3D bio printing solutions aim to successfully transplant the artificial thyroid and publish the results … [Read more...]

FDM Extruder Hot Ends with Inductive Heating

induction heat extruder 1

If you have a desktop 3D printer based on FDM / FFF technology you probably know how the extruder heating works and that the design principle has not changed for many years. The common extruder hot end is based on resistive heating where DC electric current causes heating up of a heater element. This solution is simple, well researched and cheap but it's bulky and takes some time to reach desired temperature. Inductive heating hot end is a more complex system with high frequency AC needed … [Read more...]

Vader Molten Metal 3D Printer

vader molten metal 3d printer 1

You probably know that high-end industrial 3d printers can print metal objects by using laser or electron beams on fine metallic powder but Vader is something completely different. Vader aims at small companies or professional workshop environments by implementing proprietary MagnetoJet Printing (MJP) and magnetohydrodynamic (MHD) ceramic printhead technologies to reduce the machine cost. It uses molten metal and jets it in small droplets onto a surface similary to a standard inkjet paper … [Read more...]

MakerBot Opens Innovation Centre at U.S. University

The challenge for 3D printing companies is to get their technique - which is often perceived as difficult and futuristic by many - to the masses. But how does one do such a thing? 3D printing giant MakerBot thinks the way to go is to put 3D printers in libraries and universities. These are the places innovators and great thinkers go to. Johan-Till Broer, Public Relations Manager of MakerBot estimates the number of libraries in the U.S. with 3D printers and scanners to be 500. In order to bring … [Read more...]

At ETH Zürich's Cartilage Engineering and Regeneration laboratory they have made some notable speed advancements in 3D printing of human cartilage which should lead to implantable replacements for trauma victims. Team of researchers led by Professor Marcy Zenobi-Wong's and Matti Kesti developed a process that would enable hospitals to make a full size nose implant under 20 minutes. Any cartilage implant could be produced with nose, ear and knee implants being the ones most used in surgeries … [Read more...]

3D Printing Speeds Up The Construction of The Sagrada Família

3D printing has proven te be a useful technology for architects. In China, they are building the world's first 3D printed houses, and all over the world architectural artists are using the technique to create fine art pieces. Back in 2013, I did a piece on Contour Crafting, a Californian project aiming to create 3D printed houses in less than a day. In that article, I playfully mentioned that such a technique would be good news for the Sagrada Família team - the team working on a cathedral in … [Read more...]

BoXZY Brings Additive and Subtractive Manufacturing Hybrid to Your Desktop

BoXZY desktop multitool machine

Home 3d printers are incredible machines but they have some limitations. Sometimes you just need some extra tools and capabilities to finish your project. You may want to expand your tool options and experiment with wood carving, making your own milled PCBs for electronics projects or do some metal machining. BoXZY may be the type of machine you will need since it is a multitool with easily replaceable CNC mill, 3D printer and laser engraver / cutter tool heads. Additionally to the tool changing … [Read more...]

Italian Researchers Develop a Technology to 3D Print Eyeballs by 2027

one29

An Italian research studio MHOX recently published a study which suggests that the human eyes could be replaced with 3d printed artificial eyeballs by 2027. According to their team of researchers, the artificial eyeballs could surpass the potential of the organs of sight, surpassing the human needs. The “technology” proposed by the research studio is expected to enhance, heal and correct the vision of those in need, and 3d print fully personalized eyeballs to process and record real time … [Read more...]
