SLA 3D printing, or Stereolithography, is a high-resolution additive manufacturing process that uses a focused light source to cure liquid photopolymer resin layer by layer. SLA is known for its exceptional surface finish, fine detail, and tight tolerances, making it ideal for visually critical and precision-driven parts.

There are three primary SLA light-source technologies—MSLA, Laser, and DLP—each offering different advantages depending on speed, resolution, and part size.

At Kemperle Industries, we select the appropriate SLA method based on part geometry, tolerance requirements, surface finish expectations, and production timelines.

SLA Light Source Technologies

• MSLA (Masked Stereolithography)
  Uses an LCD screen as a mask over a UV light source to cure entire layers at once. MSLA offers fast print times and high XY resolution, making it well suited for detailed prototypes and small to medium-sized parts.

• Laser
  Uses a focused laser to trace and cure resin point by point. This method provides excellent accuracy and surface consistency, particularly for parts requiring precise edge definition and smooth curves.

• DLP (Digital Light Processing)
  Uses a digital projector to cure an entire layer simultaneously. DLP combines speed and accuracy, producing uniform layers with sharp detail, especially for smaller, highly detailed components.

SLA 3D Printing Materials

We offer a range of professional-grade resins engineered for visual fidelity, strength, and functional performance:

• Standard Resins
  Ideal for concept models, presentation pieces, and visual prototypes requiring smooth surfaces and fine detail.

• Tough & Engineering Resins
  Designed to mimic ABS-like performance, offering improved durability and impact resistance for functional testing.

• High-Temperature Resins
  Engineered for applications requiring elevated thermal resistance, such as tooling inserts and fixtures.

• Flexible & Elastomeric Resins
  Suitable for parts requiring limited flexibility, snap-fit features, or soft-touch characteristics.

SLA 3D Printing Applications

SLA excels in applications where surface finish, precision, and detail resolution are critical:

• Product Design & Engineering
  High-fidelity prototypes, form-fit validation, and design verification models

• Manufacturing & Tooling
  Master patterns for molding and casting, jigs, and fixtures

• Architecture & Design
  Detailed scale models and presentation components

• Medical & Healthcare

When to Choose SLA 3D Printing

SLA is the preferred choice when projects demand exceptional surface quality, fine feature detail, and tight dimensional control, especially for presentation models or tooling masters.

SLS 3D printing, or Selective Laser Sintering, is a powder-bed additive manufacturing process that uses a laser to fuse thermoplastic powder into solid parts layer by layer. SLS is widely used for durable, functional components and production-ready plastic parts that require strength, complexity, and consistent mechanical performance.

Instead of relying on traditional support structures—such as those required in FDM or SLA—SLS uses the surrounding, unfused powder as its support structure during printing. Each part is fully encased within unused powder throughout the build.

Once printing is complete, the build is allowed to cool, after which excess powder is brushed and blown off, freeing the finished 3D printed part. This process enables complex geometries, internal channels, and nested parts without the need for removable supports.

At Kemperle Industries, SLS is used for functional prototypes, end-use parts, and low-volume production where durability and design freedom are essential.

SLS 3D Printing Materials

SLS materials are chosen for their mechanical strength, thermal stability, and wear resistance:

• Nylon (PA 11 / PA 12)
  Strong, lightweight thermoplastics with excellent chemical resistance and long-term durability, ideal for functional parts.

• Glass- or Mineral-Filled Nylons
  Reinforced materials offering increased stiffness, dimensional stability, and thermal resistance.

• Flexible Nylon Blends
  Suitable for snap-fit parts, living hinges, and impact-resistant components.

SLS 3D Printing Applications

SLS is widely used for parts that must perform under real-world conditions:

• Automotive & Transportation
  Functional housings, ducts, brackets, and snap-fit components

When to Choose SLS 3D Printing

SLS is ideal when projects require strong, production-grade thermoplastic parts, complex geometries without supports, and consistent mechanical performance across all axes.

DLSM 3D printing—often referred to as Direct Laser Metal Sintering (DMLS) or Selective Laser Melting (SLM)—is a metal additive manufacturing process that uses a high-powered laser to fuse fine metal powder into dense, high-strength parts layer by layer. DLSM is used when mechanical performance, thermal resistance, and structural integrity are critical.

At Kemperle Industries, DLSM is applied to functional metal components, complex internal geometries, and low-volume production parts where traditional machining would be impractical or cost-prohibitive.

DLSM 3D Printing Materials

We work with industry-standard metal alloys selected for strength, heat resistance, and durability:

• Stainless Steel
  Corrosion-resistant and mechanically robust, suitable for tooling, housings, and structural components.

• Aluminum Alloys

• Specialty Alloys (project-dependent)
  Materials selected based on thermal, mechanical, or environmental performance requirements.

DLSM 3D Printing Applications

DLSM is widely used for mission-critical and high-performance parts:

• Aerospace & Defense
  Lightweight structural components, brackets, and internal channels

• Automotive & Motorsports
  High-strength components, performance parts, and custom fixtures

• Industrial Manufacturing
  Tooling inserts, heat exchangers, and production-grade metal parts

• Engineering & R&D

When to Choose DLSM 3D Printing

Choose DLSM when projects require fully dense metal parts, high mechanical performance, and complex internal geometries that cannot be produced through conventional manufacturing.

PolyJet 3D printing is a high-resolution additive manufacturing process that jets and cures liquid photopolymer droplets simultaneously, allowing for multi-material and full-color printing in a single build. PolyJet excels at visual realism, fine detail, and material simulation.
