3D printing techniques have eventually become the most noticeable and remake industry of the era. Due to its range and potential, 3D printers are used in various industries including fashion, food, aeronautics, medicine, construction and device manufacturing. 3D printers are changing the general phenomenon of how things are made. It is expected that 3D printers will grow around 500 percent in coming 5 years.
With its growing impact, it is important to know about the various 3D techniques. One must consider his budget and scope of use before choosing it.
- Fused Filament Fabrication (FFF): This 3D printing technique uses strands of molten plastic thread and extrude it to build a shape. The working of this 3D printer is as similar as a spider weaves its web. This 3D technology is relatively easy to use.
The raw material, plastic filament, is cheap and affordable. Available under a price of $300, these are entry level and standard printers.
Though the cheap raw material leads to low-quality parts yet the parts are more accurately designed as compared to expensive methods.
- You get accurate colors.
- The production speed and surface finish are sacrificed when compared with expensive models.
- Stereo lithography (SLA): This 3D technology constructs objects layer by layer. It traces out the thin pattern of resin and zaps it with ultraviolet rays to harden it. The process is repeated layer by layer until the final product is formed. As each layer binds the other one, the final product that comes out is much stronger and sturdier.
If you are seeking an artwork or any professional model, dental or medical device, SLA technique is ideal.
- The strength of the 3D model is incomparable to any other model.
- It works much better that $500 3D printer.
- Due to constructing each layer, the final cost of the product is too high.
