GENERAL RECOMMENDATIONS FOR 3D PRINTING

Dive into the world of 3D printing with our comprehensive guide! Users of 3D printing often encounter problems and ask themselves questions to solve these issues. In this article, we present a series of questions that may arise when 3D printing with photopolymer. Whether you’re a beginner or an experienced maker, these general recommendations will help you optimize your prints for success. Let’s explore the key settings and parameters to achieve top-notch results.

1. How to choose the illumination time?

Refer to Resin Specifications: Check the specifications provided by the manufacturer of the resin you’re using. They often recommend a range of exposure times based on the resin’s properties.

Perform Test Prints: Conduct test prints with different exposure times to find the optimal setting for your specific resin and printer. Start with the manufacturer’s recommended time and adjust in small increments until you achieve the desired results. Standard layer exposure time: 3-5 sec. When printing models with thin walls, the exposure time should be increased to avoid the possibility of gaps. Illumination time depends on the power of the projector or laser lamp, as well as on the installation height of the lamp.

Consider Layer Thickness: The thickness of each layer (also known as layer height) affects the required exposure time. Thicker layers may require longer exposure times to ensure proper curing, while thinner layers may need shorter times.

Evaluate Print Quality: Examine the quality of your test prints carefully. Look for signs of under-curing (such as tackiness or softness) or over-curing (such as brittleness or excessive curing lines). Adjust the exposure time accordingly to achieve the best balance between resolution and strength.

Account for Print Geometry: Complex geometries, thin features, and overhangs may require longer exposure times to ensure complete curing in all areas. Adjust the exposure time based on the complexity of your print to avoid under-curing in challenging areas.

Monitor Resin Aging: Over time, resin properties may change due to exposure to light and air. As resin ages, its curing behavior may vary, requiring adjustments to the exposure time. Regularly check and adjust the exposure time as needed based on the condition of your resin.

Consult Community Resources: Engage with online forums, communities, or user groups dedicated to 3D printing. Other users may share their experiences and recommendations for optimal exposure times with specific resins and printers.
