Product Overview


What's SLS Printing Technology
Selective Laser Sintering (SLS) is an additive manufacturing process that uses a laser to selectively sinter (or melt) powdered
material, such as plastic, metal, or ceramic, layer by layer to create three-dimensional objects. It starts with a thin layer of powdered material being spread over a build platform. A high-powered laser is then used to selectively
sinter the powder in a precise pattern, melting it together and solidifying it into the desired shape. This process is repeated layer by layer until the object is complete.

SLS printing is ability to produce complex, intricate, and detailed parts with high accuracy and resolution. The process also
allows for the creation of parts with no need for support structures, reducing waste and allowing for more complex designs. Additionally, SLS can work with a wide range of materials, allowing for the creation of functional parts for a variety of industries. SLS is used in a variety of industries, including aerospace, automotive, medical, and consumer products. It is particularly useful for creating prototypes, functional parts, and complex geometries. SLS can also be used for creating molds and tooling for injection molding.

SLS Printing Applied in Automotive Industrial
SLS printed nylon material is highly resistant and perfect to create functional parts for engine bay parts and many other parts in the transportation sector. SLS printed parts are strong enough to hold the whole engine assembly and handle all heat, vibration, and static loads.

SLS Printing Applied in Medical Industrial
SLS printed orthosis already widely used these days, During the growth of children and teenagers,they always have bad living habits such as incorrect sitting and sleeping posture and long-term with unilateral satchel, resulting in spinal dysplasia.Scoliosis is mostly caused by poor posture. The conservative treatment of scoliosis mainly includes physical therapy,
orthosis and so on. sls laser sintering 3d printing orthosis improves the shortcomings of traditional orthosis in many aspects,
such as low wearing comfort, unsightly, long manufacturing cycle and so on. sls 3d printing has the characteristics of lightweight, fast and accurate forming, and can adjust the material thickness according to the needs of patients.

SLS Printing Applied in Consumer Products
Today, brands face a rapidly transforming landscape of new consumer priorities, disruptive sales models, and logistical uncertainties. But the challenge of producing a high-quality, cost-effective product stays constant. Active transparency and strategic flexibility will be required to maintain brands relevant to consumers. SLS printing can prototype end use parts directly to vertify the idea and test the market respont quickly. Help to reduce the whole product R&D circle

SLS Printing Applied in Industrial Manufacturing Tools
Leveraging 3D printing to create tools for manufacturing comes with a variety of benefits, including better pricing, faster
production, a wider range of materials available. SLS process the nylon material with very good strenth and high physical performace. and not need to process the supports that save lots of time

To choose a suitable 3D printing technology, consider the following factors:
1. Material: Determine the type of material that best suits the intended use of the shoe. For example, if flexibility and durability are important, SLS may be the best option.
2. Design: Consider the complexity and intricacy of the shoe design. SLA may be better suited for detailed designs with fine features, while FDM may be better for simpler designs.
3. Quantity: Determine the number of shoes to be produced. SLS may be more cost-effective for small-batch production, while FDM may be better for one-off or low-volume production.
4. Budget: Consider the cost of the technology and the associated materials. SLS and SLA tend to be more expensive than FDM.

We offer one-stop post-processing services

Bead Blasting
This process consists of shooting an abrasive media, usually a bead (size and type results in different surface finishes), at high pressure at a printed part with compressed air, knocking loose unfused powder while also smoothing the finish of the part. This can be done manually or automatically, with manual bead blasting relying on a foot pedal-driven system for propelling the beads as opposed to an automated tumbler, turntable or conveyer. Manual may be preferred for fragile parts.

Post-processing techniques can range from manual to almost entirely automated. For example, a company may want to smooth their Multi Jet Fusion parts; this could be done with manual sanding, though it would take a long time and be cost-prohibitive. However, it may work for one-off objects or visual prototypes.

Dying: In addition, not unlike other processes, MJF parts can be subject to any number of finishes. Though there is an MJF line dedicated to full-color 3D printing (HP Jet Fusion 580/380 series), these systems are currently designed for smaller batches. When coloring parts that haven’t been printed on those machines, dying can be performed,

either manually in pots of hot water or using automated dying equipment. Dyeing is the most common secondary post-processing technique of MJF users and may be best for parts that are visible or subject to wear, as the color penetrates the surface of the part. Dying white parts, rather than grey, offers a greater range of dying options. Manual dying, which usually involves leaving the part in an 80-100°C dye bath for about eight minutes, is comparatively inexpensive. Automated dying machines, however, may be more efficient, as they use specific programs for mixing the dye bath, as well as conditioning, dyeing, part rinsing, dye disposal, and cleaning.

Chemical polishing
This process uses a chemical to smooth the surface of printed parts without impacting its mechanical properties, resulting in a controllable level of glossiness from matt to gloss to shiny.

Painting and plating are other options for coating Multi Jet Fusion parts. Performing surface smoothing first will help achieve the best results with the least additional effort. Because every industry has its own painting specifications, the best bet is to have samples done with existing painting suppliers. Hydrographs are another method of coating. An image or pattern is floated on water, the part is dipped in it to transfer the pattern over.

Given that a layer of material is applied in the process, hydrographs also result in a smoother surface.Electroplating consists of dissolving a metal in a solution and attaching the metal particles to the surface of the printed part using an electric current. Before this process can be performed on a polyamide part, the part must be made electrically conductive through the use of electroless plating, gas activation, or a conductive coating.

In surface treatment painting, the surface of the material is coated with a layer of paint to provide protection, improve appearance, or enhance performance. The process involves several steps, including surface preparation, application of paint, and curing. Surface preparation is a crucial step in surface treatment painting.

The surface of the material must be clean, dry, and free of contaminants such as dirt, oil, and rust. The surface may also be treated with a primer or undercoat to improve adhesion and promote a smooth finish.
Once the surface is prepared, the paint is applied using various techniques, including brushing, rolling, spraying, or dipping. The type of paint used depends on the desired effect and the material being painted. For example, automotive paint is designed to withstand extreme temperatures and weather conditions, while decorative paint is used to improve the appearance of walls and furniture.
After the paint is applied, it must be cured to achieve the desired result. Curing is the process of allowing the paint to dry and harden, which may take several hours or days depending on the type of paint and the conditions in which it is applied.
In conclusion, surface treatment painting is a popular technique used to improve the appearance and performance of materials. The process involves preparing the surface, applying the paint, and curing it to achieve the desired result.

CNC Machining
CNC is also a good rapid prototyping process, but it can not process parts with complex shapes. CNC can also be used as a post-processing method to assist 3D printing process to achieve higher accuracy. The combination of the two processes solves the problems of complex structures and precision.
