Selective Laser Sintering (SLS) Service

What We Offer

Auto-mobile (Half raw material & Half primer finish)

At INAC US, we’re thrilled to offer Selective Laser Sintering (SLS), a 3D printing technology that brings your most complex designs to life. With SLS, high-powered lasers sinter powdered materials layer by layer to build robust and intricately detailed parts. Whether you’re aiming for rapid prototyping or short-run production, this technology is perfectly suited for creating high-strength components with remarkable accuracy and a fine surface finish.

Alongside the technical expertise of INAC US, you’ll have the freedom to push the boundaries of what’s possible in design and manufacturing. Let us be your partner in innovation.

vs. Stereolithography (SLA)

Advantages of SLS:

  • Strength and Durability: SLS parts are usually stronger and more durable than SLA parts, making SLS more suitable for functional prototypes and end-use parts.
  • No Support Structures: SLS doesn’t require support structures, making it easier to produce complex geometries.

Disadvantages of SLS:

  • Surface Finish: SLS parts often have a rougher surface finish compared to SLA parts and may require post-processing to improve appearance.
  • Limited Material Choices: While SLS offers strong and durable nylon materials, it doesn’t offer the same range of material options as SLA.
  • Less Precision: SLS is generally less precise than SLA, making it less suitable for parts with very fine details.

STEP5: Quality Assurance and Precision Inspection

A quality inspection is performed. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Processing and Finishing

Finishing is done by removing the supports, polishing, and applying transparency treatment. It is also possible to paint and apply plating to the formed product.

STEP3: UV-Laser Print Formation (SLA Process)

Output: The product is formed by irradiating the liquid with a laser beam of UV light and laminating it. The conditions of the external environment, such as room temperature and humidity, must be maintained.

STEP2: Model Program Generation and Support Adjustment

A program for model formation is created. Depending on the shape, it may be necessary to adjust the degree of tilt and the position of the supports.

STEP1: CAD File Submission

Upload your CAD to our online quoting platform.

STEP 3: Rendering and Scene Integration

We can also handle exterior modeling and interior structure design based on illustrations. After creating the 3D models, we can create a rendering to fit a scene. We can deliver images even if we do not proceed with production.

STEP 2: Detailed Design and 3D Modeling

Once the design is determined, drawings and 3D models will be created. The structure will be examined, taking into consideration not only the external design but also functionalities such as mating and sliding.

STEP 1: Initial Design Consultation

The first step is a meeting to discuss the project. Drawings are not required for this meeting. We will create a design from a sketch based on the overall image and concept that you have in mind.

STEP5: Quality Assurance and Inspection

We perform quality inspections. At INAC, where quality comes first, we use CMMs, gauges, and other equipment for precision checks.

STEP4: Post-Casting Finishing

Vacuum casting materials are cured and then taken out of the silicone rubber mold. Then we perform finishing such as deburring and gating, and they are made into finish products.

STEP3:Material Injuction

Liquid casting material is injected into the silicone rubber mold in a vacuum environment. 

STEP2: Mold Preparation

The silicone mold is cut open into a male and female mold, and the master model is removed.

STEP1: Mold Creation

The master model is fixed to a wooden frame and silicone is poured to create a mold.
