1. Understanding Printer Accuracy: SLA vs. SLS Technologies

When considering printer accuracy, especially between SLA (Stereolithography) and SLS (Selective Laser Sintering) technologies, it’s essential to understand the factors influencing their precision. SLA printers, known for their high resolution, rely on the optical performance, forces during printing, and the properties of the liquid resin. In contrast, SLS printers, utilizing powder-based materials, depend on laser precision, tuned print parameters, and a controlled build environment. Both technologies have their strengths and weaknesses, making a comparison necessary for specific application requirements.

1.1. Factors Affecting SLA Printer Accuracy

SLA printers’ accuracy is influenced by several key factors:

Optical Performance: The light source and optical unit must precisely cure each cross-layer.
Peeling Forces: As each layer cures, the build platform’s movement can cause stress and distortion.
Material Properties: Resin temperature, homogeneity, scattering, and viscosity affect the curing process.

1.2. Mitigating Forces in Professional Resin Printers

Professional resin printers employ solutions to minimize these forces and enhance accuracy. For example, Formlabs’ Form 4 uses:

A dual-layer flexible film tank to reduce peel forces.
A microtextured optical film (Release Texture) for airflow, preventing suction forces.

Developing and manufacturing its own materials with tightly controlled properties.

1.4. Achievable Dimensional Accuracy in SLA Printing

Dimensional accuracy measurements achieved with Formlabs’ Grey Resin V5 at 100 µm layer height, post-cured for five minutes at room temperature, are:

1–30 mm features: ±0.15% (lower limit: ±0.02 mm)
31–80 mm features: ±0.2% (lower limit: ±0.06 mm)
81–150 mm features: ±0.3% (lower limit: ±0.15 mm)

1.5. SLS Printer Accuracy: Laser Precision and Environmental Control

SLS printers are typically quite accurate due to precise laser and galvanometer control. Accuracy is determined by:
