SLA (Stereolithography)

SLA is one of the earliest 3D printing technologies to be invented. It uses an ultraviolet laser to cure liquid photopolymer resin layer by layer, producing high-precision plastic components. The surface finish is smooth and fine, with a precision of up to ±0.05–0.1 mm. It offers a wide range of material options (including ABS-like, transparent and heat-resistant materials) and is suitable for applications such as design validation, prototype modelling, jewellery and dentistry.

Working Principle: An ultraviolet laser scans the surface of the liquid resin; the irradiated area solidifies instantly, whilst the build platform descends layer by layer, stacking layers until the part is formed. Once printing is complete, the part requires cleaning and secondary curing.

SLS（选择性激光烧结）

SLS utilises a high-power laser to selectively sinter layers of nylon powder, eliminating the need for additional support structures and allowing for the design of complex internal geometries. It offers excellent mechanical properties and good toughness, using nylon and its composites, making it suitable for functional testing, snap-fit assemblies and small-batch production.

Working Principle: The laser sinter a layer of powder, with the unsintered powder naturally supporting the overhanging sections. After forming, the powder block is removed; the finished product is obtained by clearing away loose powder and can be dyed or sandblasted as required.

FDM (Fused Deposition Modeling)

FDM is a 3D printing technology that melts thermoplastic filament and extrudes it layer by layer. The filament is melted by a heated nozzle and deposited onto the build plate along a cross-sectional path; it cools and solidifies to form a layer, which is then stacked layer by layer until the part is complete.

How it works: The filament is melted and extruded through a heated nozzle, deposited onto the build plate along a cross-sectional path, and then cools and solidifies. After one layer is completed, the build plate descends or the nozzle rises to continue depositing the next layer, with layers stacked one on top of another until the part is fully formed.

SLM（选择性激光熔化）

SLM is a metal 3D printing technology that uses a high-power laser to fully melt metal powder, stacking layer by layer to form dense metal components. With strength approaching that of forged parts and a density of nearly 100%, the technology supports materials including stainless steel, titanium alloys and aluminium alloys, making it suitable for aerospace, medical implants and mould inserts.

Working Principle: Under an inert gas shield, the laser fully melts the metal powder, fusing it layer by layer. After forming, the part requires heat treatment to relieve stress, followed by post-processing such as wire cutting and machining to produce the final component.

如何选择 3D 打印工艺

Selecting the appropriate 3D printing process requires a comprehensive assessment of your part’s intended use, precision requirements, material properties and budget. Below is a brief comparison of the mainstream processes:

✓FDM (Fused Deposition Modelling): Suitable for proof-of-concept and large, simple parts; lowest cost; easy to operate
✓ SLA (Stereolithography): Suitable for high-precision cosmetic parts and jewellery models; smooth, fine surface finish
✓ SLS (Selective Laser Sintering): Suitable for complex functional parts and snap-fit assemblies; requires no support structures and offers excellent mechanical properties
✓ SLM (Selective Laser Melting): Suitable for metal functional parts; strength comparable to forged components

Our 3D printing technology team is always here to assist you. If you have questions about selecting the right 3D printing process, our additive manufacturing experts can provide professional consultation and recommend the optimal process solution tailored to your product requirements.

Surface finishing options for 3D printing

3D printing only

Once the part has been printed, only the support structures are removed; in its raw state, without any post-processing, the surface exhibits a uniform, sandblasted texture.

Drum deburring

This is a batch surface finishing process that uses a tumbling machine to remove sharp edges and burrs from the surface of parts, whilst eliminating external machining marks to create a more uniform appearance. After treatment, the surface feels smooth and has a satin-like matt finish.

sandblasting

This process involves using compressed air to propel sand at high speed onto the surface of the part, creating a uniform matt finish that masks minor imperfections; it is a common post-processing method for SLS, SLM and MJF printed parts.
