Industrial environments demand components that withstand harsh conditions while maintaining precision and reliability. One critical component in many industrial systems is the indexing target, used for accurate positioning, measurement, and alignment. Macphister Design Industries recently demonstrated how mSLA (masked stereolithography) technology can produce rugged indexing targets from tough resin, offering a new level of durability and precision for demanding applications.
This post explores how mSLA technology was applied to 3D print these specialized targets, the benefits of using tough resin, and why this approach is transforming rugged industrial applications.
What Are Indexing Targets and Why Do They Matter?
Indexing targets serve as reference points for machines and sensors to determine exact positions or orientations. They are essential in:
Robotics for precise arm movements
CNC machining for accurate tool placement
Automated inspection systems
Heavy equipment alignment
In rugged industrial settings, these targets face exposure to dust, moisture, vibrations, and mechanical impacts. Traditional manufacturing methods often struggle to produce targets that combine precision with toughness and cost-effectiveness.
How mSLA Technology Works for Industrial Parts
Masked stereolithography (mSLA) is a 3D printing process that uses a digital light projector to cure photopolymer resin layer by layer. Unlike traditional SLA, mSLA exposes an entire layer at once, speeding up production while maintaining high resolution.
Key advantages of mSLA for industrial parts include:
High precision: Layer thickness can be as fine as 25 microns, allowing detailed features on indexing targets.
Smooth surface finish: Ideal for optical or sensor-based applications requiring minimal surface irregularities.
Material versatility: Compatible with a range of resins, including tough, impact-resistant formulations.
Cost efficiency: Faster print times and less material waste compared to subtractive manufacturing.
These features make mSLA a strong candidate for producing rugged indexing targets that meet industrial standards.
Choosing Tough Resin for Rugged Performance
Macphister Design Industries selected a tough resin specifically formulated for mechanical strength and durability. This resin offers:
High impact resistance to survive drops and vibrations
Good chemical resistance against oils and solvents common in industrial environments
Thermal stability to maintain shape and function under temperature fluctuations
Excellent layer adhesion to prevent delamination during use
Using this resin with mSLA printing ensures the indexing targets can endure the physical stresses of industrial applications without sacrificing dimensional accuracy.

The Manufacturing Process at Macphister Design Industries
Macphister Design Industries followed a carefully optimized workflow to produce these indexing targets:
Design optimization: Engineers created CAD models focusing on functional geometry and printability. Features like mounting holes and alignment marks were integrated.
Material selection: The tough resin was chosen after testing multiple formulations for mechanical and environmental resistance.
Print setup: Using mSLA printers, layers were cured with precise exposure times to balance speed and detail.
Post-processing: Printed parts underwent cleaning, UV curing, and surface finishing to enhance strength and accuracy.
Quality control: Each batch was inspected for dimensional accuracy, surface defects, and mechanical performance.
This process allowed Macphister to produce consistent, high-quality indexing targets ready for rugged industrial use.
Benefits of Using mSLA Printed Tough Resin Targets in Industry
The combination of mSLA technology and tough resin offers several advantages over traditional manufacturing methods:
Reduced lead times: Rapid prototyping and production enable faster design iterations and quicker delivery.
Lower costs: Less material waste and no need for tooling reduce overall expenses.
Customization: Easy to modify designs for specific applications or environments.
Durability: Tough resin withstands harsh conditions better than many conventional plastics.
Precision: High-resolution printing ensures targets meet tight tolerances required for accurate indexing.
These benefits translate into improved operational efficiency and reliability for industrial users.
Real-World Applications and Impact
Macphister Design Industries’ rugged indexing targets have been deployed in various industrial sectors, including:
Manufacturing automation: Robots use the targets for precise positioning during assembly and welding.
Heavy machinery: Targets assist in aligning large components during installation and maintenance.
Quality inspection: Automated systems rely on targets for repeatable measurements and defect detection.
Feedback from clients highlights the targets’ resilience in dusty, oily, and vibration-prone environments, reducing downtime and maintenance costs.
Future Prospects for mSLA in Industrial Components
The success of these indexing targets points to broader opportunities for mSLA technology in industrial manufacturing:
Production of other rugged parts such as sensor housings, protective covers, and custom fixtures.
Use of advanced resins with enhanced properties like conductivity or heat resistance.
Integration with digital workflows for on-demand manufacturing and inventory reduction.
As mSLA printers and materials continue to improve, more industries will benefit from 3D printed parts that combine precision with toughness.
The use of mSLA technology by Macphister Design Industries to 3D print rugged indexing targets from tough resin shows how additive manufacturing can meet the demanding needs of industrial applications. This approach delivers precise, durable, and cost-effective components that improve machine accuracy and reliability in harsh environments.
