Common Resin Print Failure Issues
Resin printing can encounter various challenges that result in print failures. Here are some of the most common issues to be aware of:
Uncured Resin
Uncured resin can cause various issues in resin prints, including sticky prints, sticky mold bases, cracked prints, and leaking hollow prints.
Resin curing is a gradual process, and incomplete washing can lead to the presence of uncured resin on the print's surface.
This uncured resin can contaminate the IPA used for washing and cling to certain areas of the model.
To prevent sticky prints, it is important to wash the part thoroughly, potentially using separate bins for initial and final cleaning, and target problem areas for extra washing.
Adhesion Problems
Adhesion problems are a common resin print failure issue where the print does not properly stick to the build plate. This can result in the print detaching during the printing process and failing.
To prevent this issue, it is important to limit the number of prints on the build plate, give each print sufficient space, rotate prints at a 45-degree angle, and regularly check and re-level the build plate for optimal adhesion.
Partial Print
Partial print is a common resin print failure issue where a section of the print fails to fully materialize, resulting in an incomplete object.
This issue can be caused by factors such as inadequate support structures, incorrect orientation of the model, or contamination in the resin vat.
To address this problem, adjustments to support structures, model orientation, and ensuring a clean printing environment are necessary to achieve successful and complete prints.
Stuck to the FEP
This is a common resin print failure issue where the printed object adheres to the FEP film instead of the build plate.
This can happen due to a loose FEP film, insufficient exposure, incorrect leveling, or issues with supports and part orientation.
Resolving this issue may require adjusting settings such as resin profile, layer exposure time, lifting speed, and support density, as well as ensuring proper orientation and adding drain holes for hollowed prints.
Print Quality
Print quality is a common resin print failure issue that can be caused by resin contamination, misleveled build plate, resin separation, incorrect resin settings, over-curing or excessive UV exposure, and the structure and orientation of the print.
It is important to address these issues to ensure successful resin printing.
Troubleshooting Resin 3D Printing
To overcome common issues and ensure successful resin 3D printing, here are several effective troubleshooting techniques you can employ:
Checking for Cured Resin
Checking for cured resin is an essential step in troubleshooting resin 3D printing.
Firstly, ensure that the resin is free of any residue.
Next, inspect the LCD screen for any leaked or cured resin.
Additionally, examine the layer lines – if the parts are over-cured, adjust the exposure time for regular layers. If the first layer doesn't adhere or the print comes off easily, adjust the bottom exposure time.
To determine if a print is fully cured, look for a matte finish, while a glossy finish indicates that the print is still curing.
These checks help identify and resolve any issues with resin curing during the 3D printing process.
Adhesion and Vat Issues
To troubleshoot adhesion and vat issues in resin 3D printing, it is important to check the temperature and ensure it is suitable for proper adhesion.
Repositioning the print to minimize stress on the plate is also crucial, especially for tall models.
Manual leveling of the bed or vat may be necessary if the print is not adhering correctly.
Additionally, inspecting and addressing wear and tear on the interface layer is essential.
Regularly cleaning the vat and mixing the resin can prevent issues caused by debris and inconsistent printing.
If necessary, adding texture to the build plate can improve adhesion.
Exposure Time and Print Settings
Exposure time and print settings are crucial factors in resin 3D printing that can greatly affect the quality of the prints.
Exposure time refers to the amount of time the resin is exposed to the UV light during the printing process. It determines how much the resin is cured and solidified.
To troubleshoot resin 3D printing, it is important to check the exposure time. If the circles are raised more than the holes, it indicates that the exposure time is too high and should be decreased.
On the other hand, if the holes are raised more than the circles, it means that the exposure time is too low and should be increased.
Additionally, it is essential to check the print settings and ensure that they are correct for the type of resin being used. Different resins may require different settings in terms of exposure time, layer thickness, and other parameters.
Using the wrong settings can result in failed prints, deformations, or prints sticking to the vat instead of the build plate.
To determine the correct exposure time, it is recommended to use the preset settings provided by the resin manufacturer. If there is no preset available, the Resin Calibration (SL1/SL1S) feature can be used to find the appropriate values.
Furthermore, it is advisable to reduce the lift speed, especially for the initial layers, to minimize the force applied to the model. A lift speed of 5 mm/min (or 0.1 mm/s) is generally recommended for the initial layers.
Lastly, it is important to regularly check and level the build plate to ensure proper adhesion and printing accuracy.
Calibrating the Printer
Calibrating the printer is an essential step in troubleshooting resin 3D printing issues. It involves adjusting the build plate to ensure proper adhesion and leveling.
Regular calibration is recommended when a new printer arrives or after printing for some time. The goal is to balance layer height, XY resolution, and exposure time to achieve optimal print quality.
Calibration projects and evaluating printed objects help in fine-tuning the printer settings.
Printer Maintenance for Resin 3D Printing
To ensure optimal performance and longevity of your resin 3D printer, it is crucial to prioritize regular maintenance.
Here are some essential tips to help you effectively maintain your printer and maximize its lifespan.
Filtering the Resin and Cleaning the Vat
To ensure high-quality prints and maximize the lifespan of your resin printer, proper maintenance is key. This includes filtering the resin and cleaning the vat to remove any debris that could affect the photoinitiator in UV curing process.
This process involves removing any resin particulates from the vat and returning as much resin as possible to a resin container.
It also includes thoroughly washing the vat with isopropyl alcohol or a resin-cleaning solution and drying it properly to avoid diluting new resin.
This helps ensure high-quality prints and prolongs the lifespan of the vat and FEP film.
Support Structures and Print Speed
This has to do with using thicker and a higher density of supports to improve the success rate and quality of prints.
It also emphasizes the importance of using software wisely to modify support parameters and consider interconnected supports.
Additionally, the choice of resin and the condition of the FEP film are factors to consider for optimal printing results.
Print speed refers to the rate at which a resin 3D printer can produce a printed object.
