Have you ever wondered if objects can be created out of thin air? Yes, they can and 3D printing makes that possible. 3D printing is a process that is used to make 3 dimensional objects. 3D printed objects can be created from plastic, nylon, metal and hundred other various types of material.
3D printing or Additive manufacturing is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes. 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling.

Plug and play simplicity
Voted MAKE magazine’s “easiest to use” and “most reliable” 3D printer. Straight out of the box - you can get started immediately with the Cube's simple setup. Just plug it in and start. The only 3D printer certified for safe at-home use by adults and children.
Print in vibrant colors
The Cube uses material cartridges in 16 different colors including vibrant colors, neutral colors, metallic silver and glow in the dark.Order cartridges
Paleontology has been using the same, solid tools for around 150 years. However, Dr. Kenneth Lacovara of Drexel University decided it was time for the art of digging up dinosaur bones to catch up with technology.
Palentologists can now use the required skills to print in 3D to make replicas of their bone findings to send to doctors and scientists around the world. This way, the discovery can be truly researched without restrictions.
Have you ever wanted to eat your own face? Well, thanks to print in 3D, now you can! The 'Eat Your Face Machine' (EYFM) is a 3D printer developed by David Carr and the MIT Media Lab. The EYFM scans your face and then recreates it onto a block of chocolate. The end result being your face, in chocolate, ready to eat. NOM!
Brazilian footwear company Melissas caught the 3D printing bug and have been creating incredible fashion designs ever since. The shoes are made out of a proprietary plastic called Melflex using injection-molding and 3D printing. Any left over material is saved and used for the next print in 3D project, so the process is nice and green! These invisible shoes were created by Andreia Chaves.
In China, 3D printing has carved out a niche in the advanced and high value-added manufacturing sector that involves complex parts and exotic materials.
Additive manufacturing cuts out the long lead times and design techniques like metal cutting or molding.
Today’s prosthetics and implants for use inside the human body already come in a variety of sizes and designs, but 3D printing can improve them by tailoring devices to each patient’s biology or injury. Bespoke implants mean better compatibility and fewer trips to the hospital, which could potentially ease the strain on China’s already stretched social security system, and it is where Materialise hopes to leverage its expertise in 3D printing in China. The Belgian company is looking to work with doctors to design devices like jaw implants from scans of patients’ mouths, says Francois. The digital models would then be printed in medical-grade titanium.
The long-term impact on supply chains could be profound. As companies start using 3D printers to produce parts on demand, on site and only as needed, a plethora of players—from storage to shipping—would lose out in a shorter, simpler supply chain, while consumers would benefit through localized production and leaner inventories.
same component could be ready in hours
Chief among them is that it can take anywhere from hours to days to print an object. While that may be an improvement for applications like rapid prototyping, it is impractical for larger-scale production. An assembly line in Shenzhen can churn out a product in the hundreds of thousands or even millions in the same amount of time it takes to print a component. “It’s an order of magnitude slower than what it’d need to be,” says Vicari.
The compounds used to print objects are expensive and only a handful can be used due to the required performance standards.
Titanium is popular for printing industry-grade parts because the metal is lighter and stronger than steel
At-home printing will not become widespread until printers become more reliable and the tools for using them more intuitive.
Since the late 90's, 3D printing which is also known as additive manufacturing has been a fast growing method to create prototype of products. 3D printing has been beneficial to various manufacturers and start ups to create affordable consumer goods.
