Injection molding has long been the dominant method for manufacturing plastic components, thanks to its high precision and efficiency. However, recent developments in 3D printing technology have opened up new possibilities, especially for small-scale production. The STEP technology (Selective Thermoplastic Electrophotographic Process) from Evolve Additive Solutions is a groundbreaking method that enables the use of 3D printing with ABS as a viable alternative to traditional injection molding.
What is STEP Technology?
STEP is a patented process that combines the benefits of 3D printing with the quality of injection molding. The technology uses electrophotographic deposition of thermoplastic materials, which are then fused through heat, pressure, and cooling to create strong and accurate components. This method enables the production of parts in ABS and other engineering plastics with high precision and repeatability.
3D Printing with ABS Using STEP Technology
ABS (Acrylonitrile Butadiene Styrene) is one of the most commonly used plastics in injection molding due to its strength, impact resistance, and temperature durability. STEP technology uses real ABS material, making it possible to produce components with the same mechanical properties as traditionally injection-molded parts.
Properties of ABS in STEP Technology:
- Tensile strength: Up to 45 MPa, making it suitable for mechanical applications.
- Heat resistance: Glass transition temperature (Tg) around 105°C.
- Durability: High impact strength and chemical resistance.
- Precision: Layer height down to 40 microns, resulting in a surface quality comparable to injection-molded parts.
Advantages of STEP Technology Compared to Injection Molding
- Flexible production – 3D printing with STEP allows for quick design changes without the need for expensive and time-consuming molds.
- Cost-effective low-volume production – No investment in costly molds is required, making small series economically viable.
- Faster time-to-market – Prototypes and end products can be developed faster than with traditional injection molding.
- Advanced geometries – STEP enables the creation of complex structures that would be difficult or impossible to produce using traditional injection molding.
Application Examples
STEP technology is already being used in the automotive industry, electronics sector, and for the production of durable consumer products. Examples of components that can be produced with ABS using STEP technology include:
- Electronics housings – Enclosures and protective cases with high precision.
- Mechanical components – Gears and brackets requiring wear resistance and accuracy.
- Outdoor products – Parts that must withstand temperature fluctuations and UV exposure.
Summary
STEP technology from Evolve Additive Solutions is revolutionizing the production of plastic parts, making 3D printing with ABS a credible alternative to injection molding. For companies seeking flexibility, faster production, and a more cost-efficient process, STEP is an innovative and sustainable option.
