Understanding Bottom Layer Settings in Resin 3D Printing

Resin 3D printing has been gaining popularity in the maker community due to its precision and versatility. However, one aspect that often gets overlooked is the importance of bottom layer settings. In this blog post, we'll delve into why excessive bottom layers and bottom exposure times may not always be the best approach, and how finding the right balance can lead to better prints and prolonged equipment lifespan.

The Myth of More Bottom Layers Equaling Better Adhesion

Many newcomers in the resin 3D printing community tend to believe that adding more bottom layers and extending bottom exposure times will result in improved adhesion and fewer print failures. While it is essential to ensure proper adhesion of the first layers to the build plate, overdoing it can have adverse effects on the equipment.

Understanding the Impact on LCD Screens

Resin printers, including those with LCD and mono screens, are susceptible to heat and light degradation. The prolonged exposure during the bottom layers' printing process can accelerate this degradation, potentially leading to screen damage. Manufacturers have reported cases where excessive bottom exposure times have caused LCD screen burnout, resulting in costly repairs or replacements.

Finding the Right Balance

So, what is the optimal approach to setting bottom layers for resin prints? Based on experience and feedback from manufacturers, a conservative yet effective strategy is to use four to six times the normal exposure time for the bottom layers. This balance ensures adequate adhesion without subjecting the equipment to unnecessary stress.

Practical Recommendations for Bottom Layer Settings

Practical experimentation and calibration are key to finding the ideal bottom layer settings for your specific printer and resin characteristics. Here are some actionable recommendations based on real-world applications:

Limit Bottom Layers: Start with a conservative approach of four bottom layers and adjust as needed for larger or more complex prints.
Optimal Exposure Times: Aim for five to six times the normal exposure time for the bottom layers to strike a balance between adhesion and screen protection.
Avoid Overexposure: Excessive bottom exposure times can lead to adhesion issues and potential screen damage, so it's crucial to find the sweet spot for your prints.
