How it works with example
Additive Manufacturing, works by
building up a part layer by layer from a digital model, rather than by
subtracting material as in traditional manufacturing methods. The basic process
can be broken down into the following steps:
Creating a digital model:
A 3D model of the part to be
printed is created using computer-aided design (CAD) software.
Slicing the model:
Then slicing into hundreds or thousands of horizontal
layers.
Preparing the printer:
The 3D printer is prepared by
loading the appropriate material (e.g. plastic, metal, ceramic, composite) into
the build chamber or onto the build platform.
Printing:
The printer uses the sliced digital
model to build the part layer by layer, following a predetermined path. This is
typically done by extruding melted material from a nozzle, or by sintering
powders, or by photopolymerizing liquid resins.
Post-processing:
After the print is complete, the
part may undergo post-processing steps, such as removing support structures,
sanding, polishing, heat treating, or surface finishing, depending on the type
of printer and the material used.
Here's a simple example to illustrate the process:
Imagine you want to print a small
figurine. You start by creating a 3D model of the figurine using CAD software.
The model is then sliced into thin horizontal layers, which the printer will
use as a guide to build the figurine. You load the appropriate material, such
as a plastic filament, into the printer and start the print process. The
printer will follow the slicing information and build the figurine layer by
layer, using the extruded plastic to create the solid object. Once the print is
complete, you remove the figurine from the build platform and remove any
support structures. The figurine is now ready to be displayed.
Material being used in printing
3D Printing technology can use a
wide variety of materials, including plastics, metals, ceramics, composites,
and even edible materials. The type of material used depends on the specific
application and the desired end-product properties, such as strength,
durability, heat resistance, biocompatibility, or food safety.
Plastics:
There are several types of
plastic filaments are used in printing,
such as ABS (acrylonitrile butadiene styrene), PLA (polylactic acid), PET
(polyethylene terephthalate), and Nylon. These materials are affordable, easy
to use, and have a wide range of applications.
Metals:
Metals such as steel, titanium,
and aluminum can be used in to produce strong and durable parts. Printing with Metal
can be done using a variety of techniques, including powder bed fusion, binder
jetting, and direct energy deposition.
Ceramics:
Ceramic materials can be used in producing
high-strength and heat-resistant parts, such as medical implants and
high-performance engine components. Can be done using a variety of techniques,
including powder bed fusion and inkjet printing.
Composites:
Composite materials can be used to
produce parts with improved strength and durability, such as aircraft and
automotive parts. Composite Can be done using a variety of techniques,
including filament deposition and vat photopolymerization.
Edible materials:
Sugar and Chocolate can be used to
produce custom-made confections and food products. Done using a variety of
techniques, including syringe-based printing and paste extrusion.
