3D Printing

3D concrete printing (3DCP) technology is already known to offer a more efficient approach to constructing buildings. A new type of 3DCP is said to be better, resulting in walls that are a claimed 72% lighter than their conventional counterparts.

Arizona company Rosotics says it's ready to revolutionize large-scale 3D metal printing, with a new "rapid induction printing" approach that can print parts of enormous size – with radical advantages in speed, cost, safety and energy efficiency.

We might soon replace our stovetops, ovens, and microwaves with 3D printers after mechanical engineers from Columbia University successfully created a cooked slice of cheesecake made from a record-breaking seven ingredients.

It's certainly handy to know how fast gears or wheels are spinning, but equipping them with external sensors may affect their performance. That's why scientists have devised a method of 3D-printing wireless sensors right into the things.

Calcium carbonate is an impressive material, in that it combines strength, light weight and porosity. Scientists have devised a new bacteria-based method of 3D-printing the substance, for uses such as bone repair and coral reef restoration.

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.

While multi-material 3D printers do already exist, the filament they extrude is all one material at any one point in the printing process. A new system produces actual multi-material filaments, however, and they boast a very useful helical design.

3D printing technology is used not only to build things as large as houses, but also as small as snowflakes. A new material allows the latter to be much stronger than ever before, and to be printed considerably faster.

A recently finished 3D-printed home has furthered the eco-credentials of the construction method through the use of 100% natural materials, which allows it to be fully recycled at the end of its life.

While 3D printing technology does allow complex metal parts to be produced efficiently, such items often deform when stressed and heated. That may soon no longer be the case, however, thanks to a new technique developed at MIT.

Scientists have developed a new method of providing information on 3D-printed foods, by printing a QR code within the food itself. Doing so doesn't affect the taste or outward appearance of the food, nor does it require the use of any labels.

Although 3D printing technology continues to improve, it's still limited by relatively long print times and low resolution. A new technology could help, by simultaneously utilizing multiple small print nozzles instead of a single big one.

When you played with action figures, you probably tried picturing yourself having the same adventures they were. Well, doing so is about to become easier, as Hasbro is offering to a put a 3D-printed miniature copy of your face on one of its figures.

3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by utilizing sound waves.

Researchers at EPFL have demonstrated a light-based 3D-printing method that's about 30 times faster than conventional additive manufacturing, creating objects in 20 seconds that would normally take more like 10 minutes thanks to photocurable resins.
