Available Materials for SLS

Alumide for Selective Laser Sintering


Alumide is a metallic grey, aluminum-filled polyamide 12 powder, which is characterized by its high stiffness, metallic appearance, and good post-processing possibilities. Alumide is suitable for complex models, prototypes, small series of components, and functional models. 

PA2210 for Selective Laser Sintering

PA 2210 FR

PA 2210 FR is a white Polyamide 12 powder with a halogen-free, chemical flame retardant. In case of fire, a carbonating coating arises on the surface of the part, isolating the plastic below. PA 2210 FR fulfills the flame protection classification UL 94 / V-0 from a wall thickness higher than or equal to 2 mm.

PA3200 for Selective Laser Sintering

PA 3200 GF

PA 3200 GF is a white, glass bead-filled polyamide 12 powder, characterized by an excellent stiffness in combination with good elongation at break. This material is excellent for applications such as final parts within the engine of cars, deep-drawing dies, or other uses that require stiffness, high heat distortion temperature, and low abrasive wear.

SLS 3D Printing Technology Overview

Selective Laser Sintering (SLS), also known as Laser Sintering (LS), uses a CO2 laser to heat and fuse the durable thermoplastic powder to build versatile parts with high elongation at break. 3D printed production parts and prototypes provide lightweight, heat, and chemical resistant solutions.

SLS is one of the most versatile and commonly used additive manufacturing technologies. Common uses of SLS-printed parts are in airplanes, wearables, machine components, and production tools.

Selective Laser Sintering

SLS 3D printing process

The working principle of 3D printing is the same as that of a traditional printer. It’s just that 3D printing does not eject ink, but ejects materials such as liquid or powder.

The rapid prototyping equipment using light-curing and paper stacking technology superimposes the printing materials layer by layer through computer control and finally becomes a reality.

The 3d printing process steps usually include the following main steps: modeling, slicing, printing, and post-processing.

Advantages and disadvantages of SLS 3D printing

A variety of materials can be used. Available materials include polymers, metals, ceramics, gypsum, nylon, and other powder materials.Rough surface. Need post-processing
The manufacturing process is simple. Because there are more materials available, this process can directly produce complex-shaped prototypes, three-dimensional construction of cavity molds, parts, and tools according to different materials.There is a peculiar smell during the sintering process.
High precision. Generally, the tolerance of (0.05-2.5) mm within the entire range of the workpiece can be reached.It is impossible to directly mold high-performance metal box ceramic parts, and it is easy to warp and deform when molding large-size parts.
No supporting structure is required.The processing time is relatively long.
The material utilization rate is high and the price is cheap.The equipment is expensive and more suitable for industrial manufacturing.
