SLA, which stands for Stereo-lithography is
one of the many types of three-dimensional printing. It can be described as the
manufacturing process which helps to create models according to the
specifications and requirements of the client. Models or prototypes created
through this method are replicas of the original idea.
SLA models can be created in a number of
sizes and variety of other specifications. Stereo-lithography is also known as
optical fabrication, photo solidification or solid imaging. It is also the most
common plus extensively used methods of rapid
manufacturing or prototyping. Stereo-lithography or SLA creates solid
three dimensional objects and 3D parts with excellent precision and
high-quality surface finish.
What is the Process of Stereo-lithography?
In the process of SLA or Stereo-lithography, a computer program is generated. It creates a 3D file of the model that is then divided into successive layers. Once the design is complete and the support structures are also added, this 3D file or program is taken to a Stereo-lithography machine for printing.
This machine uses UV laser beam and draws the first layer on a VAT of UV liquid resin. When exposed to the laser beams the resin cures. After the completion of the first layer, the printing platform lowers itself by 0.05 to 0.15 millimetre and the laser traces the next layer by curing the resin and connects it to the earlier layer.
The process goes on and layer after layer is
created until we get a prototype created in the resin. Now the machine lets the
extra resin drain away. The technicians remove the support structures and also
wash the model. Now the model is ready to be painted according to the
requirements of the clients. SLA or Stereo-lithography is faster and
cost-effective as compared to other methods of creating prototypes.
There are numerous renowned companies
claiming of offering the best solutions and support. They have a team of
professionals who leave no stone unturned in offering the best rapid prototyping services. They also have the detection equipment
making them have the ability to use a variety of processing means to endow with
a wide range of application. These companies also endow you with technical
support and possible to complete set of prototype services.
