Our 3D Printing Process Options

Boyi can enable you to quickly and easily obtain high-quality custom 3D printed parts. We have over ten 3D printers, including SLA, SLS, and SLM. This allows for 3D printing of plastics and metals, and provides options for prototype design and production.

stereolithography sla

Stereolithography (SLA)

SLA uses ultraviolet laser to irradiate photosensitive resin and solidifies layer by layer to construct the desired shape. Can quickly create complex models and prototypes, accelerating the product development cycle.

selective laser sintering sls

Selective Laser Sintering (SLS)

SLS is suitable for the production of functional parts. By using laser beams to sinter powder materials layer by layer, high-quality 3D printed parts with complex structures are manufactured without the need for support.

3D Printing Overview

What is 3D printing? How does 3D printing work?

3D printing is an additive manufacturing technology that creates objects by stacking and fusing materials layer by layer, without the need for traditional cutting or material removal methods. It is fast, cost-effective, and can manufacture complex geometric shapes, commonly used in prototype design and lightweight object manufacturing in the engineering field.
Modeling: Create or obtain a 3D model. Slicing: The model is sliced into thin layers. Printing: The object is gradually built layer by layer. Curing/Melting: Materials are bonded together. Cooling/Solidifying: Each layer cools or solidifies after completion. Repeat Layers: Repeat these steps until the entire object is finished.

What is the most popular 3D printing technology?

The most popular 3D printing technology varies depending on its specific purpose and project requirements. For example, the required materials, size of printed objects, complexity, and required accuracy. If you need assistance in finding the most suitable 3D printing process for you, you can consult and plan with our team of additive manufacturing experts.
