FUNCTIONAL PARTS & PROTOTYPES TOOL FREE IN RECORD TIME

Selective Laser Sintering (SLS)

SLS produces plastic parts using a laser to sinter thin layers of powdered material one layer at a time. The coater spreads an initial layer of powder over the build platform, then the cross-section of the part is scanned, sintered, and solidified by the laser. Simultaneously, the build platform drops down one-layer thickness (typically 100 or 120µm), then a new layer of powder is applied. The process repeats over and over until all the layers are formed. Unlike other additive technologies, SLS does not require support structures.

Additive manufacturing with selective laser sintering (SLS) offers excellent quality and throughput. The technology lends itself to complex design concepts not possible with injection molding. SLS Additive Manufacturing has resolved the issues of long lead time and upfront investment required for injection molding tooling. Calculating the cost of production and quality of the parts, speed-to-market, industrial SLS stands as a viable value-adding manufacturing process.

SLS is typically used for functional parts because of their good mechanical properties and high chemical resistance. The default surface properties of an SLS part are somewhat rough (≈35µm roughness value). The color of the base powder is typically white. The SLS parts can be dyed, painted, sealed, coated, and over-molded. The surface can also be mechanically or chemically treated to improve the roughness and reduce the porosity. SLS parts are well suited for machining to enhance the accuracy and surface finish. The result resembles CNC parts, yet complex with a lead time of additive manufacturing.

BENEFITS AND FEATURES

  • Parts possess high strength and stiffness, in addition to good chemical resistance
  • Available Biocompatible materials according to EN ISO 10993-1 and USP/level VI/121 °C
  • Complex parts with interior components, channels, can be printed without trapping the material inside
  • The fastest additive manufacturing process for printing functional, durable, prototypes or end-user parts
  • The vast variety of materials and characteristics of Strength, Durability, and Functionality
  • Excellent mechanical properties. The material is often used to substitute typical injection molding.

APPLICATIONS

INJECTION MOLDING EOAT FOR LARGE AUTOMOTIVE PARTS

KEY FEATURES
  • Quick connect for fast tool changing
  • No adjustments required
  • lightweight and organic structure
  • Engineered for maximum stiffness with minimum material
  • Internal vacuum channels for vacuum cups
  • lightweight custom grippers

GRIPPER DESIGN

For the molding EOATs, grippers usually pick up the runner and sprue. The traditional tool uses a heavy and expensive mechanical gripper. In this case, the lightweight body and gripper were 3D printed and the lightweight cylinder was integrated into the tool.
More than one gripper was connected to the same actuator.

QUICK CONNECT FOR FAST CHANGEOVER
Our proprietary quick connect system speeds up the changeover of EOATs, improving the efficiency of the production line.

CARTON EXTRACTING TOOL FOR A PACKAGING EQUIPMENT OEM

THE ORIGINAL METAL TOOL WAS CONVERTED TO NYLON 12 USING OUR DESIGN AND ENGINEERING PROCESS.

QUICK OVERVIEW
  • Lightweight
  • Added more optional air channels without impacting the cost
  • No minimum quantity or set up fee
  • 3 days delivery
  • The final price was equivalent to the machined part

DEVELOPMENT INFORMATION

All 3D printed parts are designed using DAFM principles. The use of Topology Optimization provides the optimum material layout according to design space and loading case in which design variables are defined as a fictitious density for each element, and these values are varied from 0 to 1 to optimize the material distribution. The result is an organic structure representing the minimum material required to support the load.
All the air channels can be integrated without worrying about their machinability.
A combination of plastic taping and inserts was used in this application.

A LARGE VACUUM MANIFOLD DESIGNED TO BE PRINTED IN SECTIONS

A LIGHTER TOOL OF 1.5KG. TO CARRY A 3KG. LOAD IS IN CURRENTLY BEING DESIGNED.

KEY FEATURES
  • Incredibly lightweight vacuum manifold
