3D Printing Materials

Industrial 3D Printers

From scale models, gifts and clothing to prosthetic limbs, hearing aids and the prospect of 3D-printed homes, the possibilities seem endless.So you may ask what are the materials that can be used in 3D Printing , well the range is increasing and the possibilities seem to be multiplying rapidly .

3D Printers – How Do They Work?

The 3 Dimensions – Working Principles of Linear Robots

In order to be able to print a physical object, i.e. an object in 3 dimensions, a 3D printer needs to be able to move on 3 coordinate axes (i.e. most commonly referred to as length, width and height). But how do you tell the machine where to put its nozzle at a specific moment? Mathematicians generally refer to the term of “Cartesian coordinate system” in order to specify the position of a given point in 3-dimensional space. But don’t worry, we are not going to do any maths here. Just have a look at Illustration 3 in order to understand what is meant by this. The general convention is to use the X, Y and Z axes in order to map a specific point in a 3D coordinate system.


If thinking in 3 dimensions may seem confusing in the beginning, just think about 2 dimensions to start out. Remember how your inkjet printer used to work? It used only 2 dimensions, i.e. the X and Y axis and may therefore help you understand the process. Once you had finished typing your document, the computer translated the document into coordinates for your printer. A moving head printed the letters on paper, usually on one fixed axis (going from left to right and back – i.e. the horizontal axis) while little motors drove wheels which advanced the paper page on the other axis (up and down – i.e. the vertical axis). The principles are the same for a 3D printer, except that it is able to move in one more direction (depth) and thus is able to physically print objects.

Nearly every 3D printer is built around the principle that its 3 principal axes are linear. This means that their axes are at right angles to each other and that they move in straight lines (that is: they do not rotate). Machines which use this principle are known as linear robots or cartesian coordinate robots, Typical examples of linear robots are 3D printers, but also computer numerical control (CNC) machines.

In order to move along these 3 axes, 3D printers generally make use of fixed rods, timing belts and pulleys, in order to manoeuvre the print head(s) and or the print platform to the exact position needed. These timing belts and pulleys are connected to small motors, which are generally referred to as “stepper motors” .

3D Printer, What can it Print ?

Medical Field :

It's clear that 3D printing has the potential to transform several industries. Take the health field — medical professionals have used 3D printing to create hearing aids, custom leg braces and even a titanium jaw. Even 3D Printed Body parts including Kidneys , Skin , ears are a reality and have been used and demonstarted .

Airwolf 3D printed 201 Prosthethic Hands during a Print-a-Thon that they organized in 2014 !!!

Space :

NASA has tested 3D printers that will let Mars-bound astronauts print what they need as they travel and this includes not just tools but also food !!!!

Construction

The KamerMaker is a 3D printer large enough to print entire rooms and a Chinese company has already created a Giant Printer which can build 10 medium size houses with a concrete mix in a day and is innovating further !!!

Food :

Pizzas ,Candy , Chocolates , Blueberries ,Jello, Cakes , Cookies and the list goes on and on . Hershey & 3D Systems Unveil New Cutting-Edge Chocolate 3D Printer at CES

Transportation :

Cars have already been made in 2014 and many manufacturers have already models on the way , with planns to sell their products in the open market !!!

Clothing :

Yes , when we can have food is Clothing far behind ...have a look at the video .

Could 3D printing eventually change the world and even make mass manufacturing obsolete? We'll have to wait and see
