3D printing is a subset of additive manufacturing. Additive manufacturing is where a part is made by adding material, whereas the subtractive manufacturing process is subtracting (successively cutting) material. In 3D printing, a 3D printer makes a three-dimensional object from a CAD file. There are a variety of materials and 3d printing technologies available, making it easier than ever to create parts for all sorts of industries.

Many people assume 3D printers are a new technology, though you might be surprised to know they’ve been around since the 1980s. However, printers up until 2009 were mostly used for industrial purposes, and were prohibitively expensive to use for most. In our time, businesses around the world are able to utilize 3D printers to produce parts for manufacturing purposes with improvements to 3D printing costs.

3D printing process

3D printing is consist of three processes which are called software, material and printing.

3D printing software: 3D printing relies on a fully-automated software system that controls everything such as material, layer quality, position of workpiece and so on. These systems vary significantly, but all have the same core elements.

3D printing materials: Material selection determines both the mechanical properties of the final part and the specifics of the printing process required to fabricate it.

Different materials would be selected for printing processes according to expectation of behaviours. In the graph, there are several different materials which are used with 3d plastic printing process with the exception of Aluminium. This diagram reveals the compression of stress/strain curve of materials. According to this graph, we can have opinion about that how different these engineering ratios of materials such as young’s modulus, stiffness and so on.

Application constraints come first when selecting a material but, fabrication constraints can equally make or endamage your part. As in conventional manufacturing, some materials are easier to print than others.

3D printing process: This is the physical process by which FFF 3D printers deposit material layer-by-layer in the shape of a part. The particulars of this process affect part quality, precision, and print time.

Markforged 3D printers utilize processes based on Fused Filament Fabrication (FFF, also known as FDM). FFF 3D printing is comprised of three relatively simple components:

Here are some of my projects:

Mark Two

All these geometries are printed with Markforged. Mark Two desktop series printer is used. Carbon fiber and fiberglass are included in some geometries and in this way, stiffness of these parts are increased significantly.
