3D Printing

Selective Laser Sintering (SLS)

Selective laser sintering (SLS) uses a CO2 laser to fuse a nylon-based powder layer by layer until the final thermoplastic part is manufactured.

What is 3D printing SLS?

Selective Laser Sintering (SLS) is an industrial 3D printing process that can produce accurate prototypes and functional production parts in less than one day.

A wide selection of nylon-based materials and thermoplastic polyurethanes (TPUs) allows you to produce durable final parts that require heat resistance, chemical resistance, flexibility or dimensional stability.

How it works?

The SLS machine begins by sintering each layer of the part geometry into a heated layer of nylon-based powder.

After each layer is fused, rollers pass through the bed to dispense the next layer of powder. This process is repeated layer by layer until the build is complete.

When construction is complete, the entire powder bed with packed parts is moved to a branching station where it is raised and then the parts are removed from the powder bed. Perform an initial brushing manually to remove most of the loose powder.

The parts are then sandblasted to remove any remaining powder before finally reaching the finishing department.

Selective Laser Sintering (SLS) Materials:

PA 11 Black (PA 850)	Highest elongation at break of all additively manufactured nylons，Uniform deep-black color that showcases features and provides a clean appearance
PA 12 White (PA 650)	Economical material choice，Strength and stiffness
PA12 Mineral-Filled (PA620-MF)	Highest stiffness of all additively manufactured nylons,Temperature resistance
PA12 40% Glass-Filled (PA614-GS)	Long-term wear resistance,Stiffness and dimensional stability
Polypropylene Natural	Chemical resistance,Durable, low weight material
TPU 70-A	High elongation at break,Flexibility

3D Printing

Stereolithography (SLA)

The SLA (Stereolithography) is formed of thousands of thin layers in the liquid thermosetting resin surface until the finished part is formed by using an ultraviolet laser.

SLA Design Guidelines：

Our basic guide to stereolithography includes important design considerations to help improve part manufacturability, enhance appearance, and reduce overall production time.

What is 3D printing SLA?

Stereolithography (SLA) is an industrial 3D printing process, for creating in just a conceptual model day, the appearance and complex prototype parts with complex geometries.

Use SLA to choose a variety of materials, extremely high feature resolution and high-quality surface finish.

How it works?

The SLA machine begins to draw the layers of the support structure, and then draws the part itself, aiming at the surface of the liquid thermosetting resin with an ultraviolet laser. After imaging a layer on the resin surface, the build platform moves down, and the recoating rod moves through the platform to coat the next layer of resin.

Repeat this until the entire part is manufactured and a 3D solid model is obtained.

The newly manufactured parts are taken out of the machine and entered into the laboratory, where a solvent is used to remove any additional resin.

When the parts are completely clean, manually remove the support structure. From there, the parts are subjected to the ultraviolet curing cycle to completely cure the part outer surface.

The final step of the SLA process is to apply any custom or customer-specified finishing.

Metal 3D Printing

Direct metal laser sintering (DMLS) uses a fiber laser system that draws onto a surface of atomized metal powder, welding the powder into fully dense metal parts.

Direct metal laser sintering (DMLS) is an industrial metal 3D printing process that builds fully functional metal prototypes and production parts in 7 days or less.

A range of metals produces final parts that can be used for end-use applications.

How it works?

The DMLS machine begins to sinter each layer-first the support structure of the base plate, and then the part itself-with a laser aimed at the metal powder bed.

After the cross-section of the powder, the layer to be micro-welding, the build platform moves downward, recoating blade moves through the internet to the next layer of powder is deposited into an inert build chamber.

This process is repeated layer by layer until the build is complete.

After construction, the parts manual brushing to remove most of the initial loose powder, followed by appropriate heat treatment cycles, while still secured to the support system to relieve any stress.

Remove the part from the platform, remove the support structure from the part, and then perform any required sandblasting and deburring.

The density of the final DMLS part is close to 100%.

Advantages of 3D printing：

3D printing is a revolutionary technology that can produce parts that cannot be manufactured directly based on your CAD data. The advantages of this process include the ability to produce strong, complex geometries, internal lattice structures, conformal cooling channels, and other features that cannot be produced by traditional machining. Parts can be manufactured quickly with minimal material waste, making them ideal for next-generation engineering in aerospace, medical, automotive, and other industries.

3D printing has many benefits, especially if you know how to optimize product designs to take advantage of them. E.g:

01. Metal 3D printed parts are completely dense, combined with complex geometric shapes and precise internal features, which cannot be manufactured using traditional processing alone.

02. The design can be completed quickly with minimal material waste while maximizing strength.

03. Multiple identical parts can be built on one platform at a time, thereby greatly improving production efficiency.

04. The conformal cooling channel greatly improves performance and resistance to thermal stress, making it ideal for aerospace and automotive applications.
