Resin Printer Failed Prints: A Practical Guide to Mastering Your Prints

Resin Printer Failed Prints


Embarking on the journey of resin 3D printing is an exciting venture into the world of intricate designs and innovative creations. However, the occasional setback of a failed print can be a frustrating roadblock. Fear not! In this comprehensive guide, we’ll delve into common challenges faced by resin printers and explore practical, human-friendly solutions to ensure your 3D printing experience is as seamless and satisfying as possible.

Understanding the Nuts and Bolts of Resin Printing Glitches

Let’s dive deep into the common hiccups faced by resin printers and equip ourselves with hands-on solutions for a smoother 3D printing ride.

1. Contaminated Resin: Maintaining Purity for Impeccable Prints

Nothing is more disheartening than a print ruined by contaminated resin. Before each print, give your resin a thorough check. Use a plastic scraper to remove any debris, ensuring a clean start. Be cautious not to introduce alcohol or other liquids during the cleaning process to prevent additional contamination. Make it a practice to clear out any cured resin or residue from the vat before initiating a new print to preserve a pristine printing environment.

2. Dirty LCD Screen: Clearing the Path to Print Perfection

A smudged or dirty LCD screen can significantly impact print quality. Grab a plastic scraper and gently clean the screen to remove any accumulated residue. Avoid the use of harsh chemicals or metal tools, as they can damage the screen. Regular maintenance is key, especially for printers with high UV power like the Photon Mono X. Consider adjusting UV power settings to maintain optimal performance.

3. Overloading the Build Plate: Striking a Balance Between Quantity and Quality

While the temptation to maximize productivity by loading up the build plate is strong, overloading can strain your printer, resulting in failures. Start conservatively by printing a few models at a time and gradually increase as you gain experience. For larger projects, strategically angle prints at 45 degrees to reduce strain on supports and enhance overall print quality.

4. Incorrect Print Orientation: A Simple Tilt for Enhanced Results

Printing models in a straight orientation can increase the likelihood of failure. Introduce a 45 degree rotation to distribute weight evenly, reducing strain on supports and facilitating easier removal from the build plate. This adjustment is universally beneficial, whether you’re using an Anycubic Photon, Elegoo Mars, or Creality LD-002R.

5. Improper Supports: Establishing a Strong Foundation for Quality Prints

Inadequate or poorly placed supports contribute significantly to print failures. Utilize advanced slicing software like Lychee Slicer or PrusaSlicer for precise support placement. Optimize support density, consider angled supports, and thoroughly review the support structure before initiating a print to ensure stability and prevent failures.

6. Unlevel Build Plate: The Importance of Balance

A misaligned or unlevel build plate can adversely affect print quality. Regularly check and re-level the build plate to ensure optimal printing conditions. Using low grit sandpaper, gently smooth the build plate surface to improve bed adhesion and prevent uneven curing or print failures.

7. Damaged FEP Film: Safeguarding Against Resin Leaks

The FEP film is a critical component, and any damage or holes can lead to failed prints. Regularly inspect the FEP film for scratches, smudges, or holes. Even minor imperfections can impact print quality. If damage is detected, replace the FEP film promptly. Keeping spare FEP film sheets on hand allows for quick replacements, and opting for high-quality films designed for your specific printer model is advisable.

8. Incorrect Exposure Time: Precision in the Curing Process

Properly setting the exposure time is fundamental for successful resin prints. Exposure time determines how long the resin is exposed to UV light, influencing the curing process. Consider the specific curing properties of the resin being used and consult manufacturer guidelines. Regularly calibrate printer settings, including exposure time, layer height, and other relevant parameters. Experimentation and careful calibration, starting with the recommended exposure time and adjusting based on test prints, lead to finding the perfect exposure time for your resin 3D printer.


Addressing these common challenges head-on empowers you to troubleshoot and rectify resin printer failed prints effectively. By implementing practical solutions, you set the stage for successful, flawless prints, transforming your 3D printing journey into a gratifying experience. Mastering the art of troubleshooting is key to unlocking the full potential of your resin 3D printer, and with these human-friendly approaches, you’ll navigate the intricacies of the printing process with confidence and expertise.
