GSG-Tech's Online 3D Printing Service

Metal 3D Printing (SLM)

Selective Laser Melting (SLM) uses a high-energy laser to fully melt fine metal powder layer by layer, producing dense and high-strength metal components. Compared to plastic-based 3D printing, SLM delivers superior mechanical performance and heat resistance, making it ideal for demanding applications such as aerospace, medical, and industrial parts. It is especially suited for complex geometries that are difficult to machine using traditional methods.

Multi Jet Fusion (MJF)

Multi Jet Fusion (MJF) builds parts by applying fusing and detailing agents onto a powder bed, which are then bonded using heat. Unlike laser-based powder processes, MJF enables faster production speeds and more consistent mechanical properties across parts. It is widely used for functional prototypes and end-use nylon components that require strength, accuracy, and fine detail.

Advanced Photopolymers

Advanced photopolymer technologies combine high-performance resins with improved curing methods to achieve better mechanical properties than standard SLA or PolyJet materials. These materials offer enhanced strength, durability, and thermal resistance, making them suitable for functional testing and applications where traditional resins may fall short.

PolyJet

PolyJet technology jets tiny droplets of liquid photopolymer onto a build platform and cures them instantly with UV light. Unlike SLA, PolyJet can print multiple materials and colors in a single build, including rubber-like textures. This makes it particularly suitable for prototypes that require realistic appearance, flexibility, or multi-material simulation.

Selective Laser Sintering (SLS)

SLS uses a laser to sinter thermoplastic powder, typically nylon, into solid parts layer by layer. Compared to SLA, SLS does not require support structures, allowing for more complex internal geometries. It is known for producing durable, functional parts that perform well in both prototyping and low-volume production.

Stereolithography (SLA)

SLA uses a UV laser to cure liquid resin into solid layers with extremely high precision. Compared to powder-based processes like SLS or MJF, SLA delivers smoother surfaces and finer details, making it ideal for visual models, transparent parts, and applications where appearance is critical.

Post-processing improves the surface quality, appearance, and performance of 3D printed parts. Our services support both plastic and metal components, making them suitable for prototypes, functional parts, and end-use products.

As-Machined

Provides a cost-effective option with visible tool marks, as the surface is left directly from the CNC machine.

Anodizing

Improves corrosion and wear resistance while allowing for color dyeing, ideal for aluminum components.

Polishing

Achieves a high-gloss finish, reducing surface roughness and enhancing the aesthetic appeal of the metal.

Sandblasting

Uses pressurized sand or other media to clean and treat the surface, creating a uniform matte finish.

Brushed Finish

Creates a unidirectional fine texture, reducing the visibility of marks and scratches on the surface.

Powder Coating

Provides a thick, durable, and wear-resistant coating with excellent color and texture options for various surfaces.

Electroplating

Bonds a thin metal layer to the part, enhancing wear resistance, corrosion resistance, and surface conductivity.

Black Oxide

A conversion coating for ferrous metals that improves corrosion resistance and minimizes light reflection.

Electropolishing

An electrochemical process that smooths and brightens the surface while significantly improving corrosion resistance.

Alodine

A chromate conversion coating for aluminum that provides corrosion protection and improves paint adhesion.
