3D Printing Company Explains Various 3D Printing Technologies
3D printing has become an incredibly dependable production process in recent times. Generally, the applications involving this technique involve complex constitutions and low volumes. The best examples that often match the above are aerospace and medical applications.
In this post, we will list some common technologies used by the average 3D printing company along with their uses and advantages.
Top 3D Printing Company Technologies in Use These Days
Here’s a look at the following well-used techniques in the market at the present:
FDM (Fused Deposition Modeling) - This is one of the most commonly used methods for printing plastic parts. This is due to its low price and quick speed in creating physical models. Whether we talk about an entry-level machine or the best FDM 3D printer in the industry, they all work by extruding a plastic filament and placing it on the platform in several layers.
SLA (Stereolithography) - It is where industrial 3D printing finds its origin. Stereolithography is great for creating parts that require increased detailing, smooth finish, and little tolerance. For this reason, there are several SLA desktop 3D printers for medical applications, such as microfluidics and various models.
SLS (Selective Laser Sintering) - This technology forms solid plastic by combining nylon-based powders. This method provides durable products that are useful in functional testing because the parts are produced from actual thermoplastic substance. Additionally, the parts made through the best SLS 3D printers have greater strength and tougher surface finishes than the ones made through Stereolithography.
PolyJet - This method is capable of creating products with several customizations to various attributes, such as the colours and the substances used in creating the products. This feature makes it perfect for designers who have to create elastomeric prototypes as they can iterate and validate their designs without requiring additional tools early in the development cycle.
On the other hand, this also makes it more expensive, so if you have to produce a simple design using a single, rigid plastic, you may prefer economical options such as SLS or SLA.
DLP (Digital Light Processing) - Like Stereolithography, DLP also uses light to cure liquid resin. The major difference between the SLS and the DLP resin 3D printer UK based companies use is the digital light projector screen used by the latter. SLA, however, involves the use of a UV laser. This leads to quicker build speeds, since DLP 3D printers become capable of imaging a while layer of the model in one go.
MJF (Multi Jet Fusion) - The Multi Jet Fusion technology is similar to Selective Laser Sintering as it also combines nylon powders to create functional components. But it doesn’t sinter the powder with a laser; it instead uses places fusing agents on the nylon powder using an inkjet array.
The various technologies mentioned above come with their unique advantages given their applications. From increasingly consistent mechanical properties through techniques such as Multi Jet Fusion to better surface finishes by stereolithography, each brings benefits and is useful for multiple applications depending on your requirement.
