Photopolymer resin is a liquid photosensitive material used in resin 3D printing. When exposed to light of a specific wavelength, the resin undergoes a photopolymerization reaction and solidifies layer by layer to form a 3D model.
Different types of photopolymer resin may require different light source wavelengths. Before use, ensure that the resin's curing wavelength is compatible with the printer's light source. Refer to the product instructions to select a suitable printer and printing parameters.
The density of currently available photopolymer resin products is approximately 1.05–1.25 g/cm³ at 25°C. For the exact value, refer to the Technical Data Sheet (TDS) of the corresponding product.
For the exact value, refer to the Technical Data Sheet (TDS) of the corresponding product.
The batch number identifies the production batch, while the date markings indicate the production date and expiration date. Coding rules may vary between products. Please refer to the label on the resin bottle.
If you need to verify batch or date information, provide the complete code and a clear photo of the product label to Technical Support.
Photopolymer resin requires exposure to UV light of a suitable wavelength to cure. Unlike some two-part casting materials, it does not cure on its own through mixing or standing.
First, check the printer's condition and printing settings, including the light source, exposure parameters, and build plate leveling. Then check the condition of the resin.
Use the recommended parameters for the specific printer and resin to perform a test print. Do not conclude that the resin is defective based solely on a single failed print.
This issue may be caused by model mesh defects, improper support settings, incompatible exposure parameters, or excessively high resin viscosity.
We recommend troubleshooting the issue step by step:
This issue may be related to resin flowability, resin reflow time, support settings, or exposure parameters. The exact cause cannot be determined from the print result alone.
Check whether the resin temperature meets the recommended requirements. The optimal operating temperature is 25–30°C. If the temperature is too low, resin reflow may be slower.
You can also check and adjust the following parameters one by one:
This issue may be caused by insufficient adhesion, improper model orientation, or inadequate support settings.
The exposure time, model orientation, and support height should be adjusted according to the model and printing conditions.
Model delamination or cracking may be caused by incorrect exposure parameters, improper hollow model design, residual resin or cleaning solution inside the model, or unsuitable storage conditions.
We recommend troubleshooting the issue as follows:
Surface whitening may be caused by cleaning residue, incomplete drying, or incorrect exposure settings. Whitening alone does not necessarily indicate insufficient curing.
First, check whether the model has been cleaned thoroughly and ensure that it is completely dry before post-curing.
If insufficient exposure is confirmed, recalibrate the Normal Exposure Time.
A brittle model may be caused by the resin's material properties, exposure parameters, post-curing conditions, model design, or storage environment.
We recommend the following troubleshooting steps:
Visible layer lines, holes, or bubbles may be caused by mechanical issues, abnormalities in the Release Film or LCD Screen, impurities in the resin, air bubbles, or incompatible exposure parameters.
We recommend the following troubleshooting steps:
Oversized models or undersized holes and gaps may be caused by excessive exposure, resin flow conditions, printer accuracy, or material curing shrinkage.
We recommend the following troubleshooting steps:
Yellowing during storage may be related to the resin's material properties, prolonged UV exposure, ambient temperature, or post-curing conditions.
We recommend the following measures:
Yes. Different resin models or colors may require different exposure and rest time settings.
Refer to ELEGOO's official recommended parameters and calibrate them according to the printer model, resin model, color, and layer thickness.
We recommend printing a test model before starting a full print.
Refer to the ELEGOO Official Recommended Resin Settings.
Select the settings that correspond to your printer, resin model, color, and layer thickness.
Recommended parameters can be used as a starting point. Actual settings should be adjusted according to the printing environment and test results.
The layer thickness and Transition Layer Count should be determined according to the printer's performance, resin properties, and the model's accuracy and printing requirements.
Prioritize the recommended settings for the specific Water Washable ABS-Like Resin and printer. Do not select a profile based solely on its preset name.
If the slicing software does not include a matching profile, create a custom profile based on the official recommended values and print a test model to verify the results.
Use photopolymer resin in a well-ventilated environment away from direct sunlight. Maintain the ambient temperature according to the product label or instructions.
Temperature changes may affect resin flowability and printing quality.
Ensure that sufficient clearance is maintained around the printer for heat dissipation. For specific requirements, refer to the user manual of the corresponding printer model.
Standard photopolymer resin is generally cleaned using Isopropyl Alcohol (IPA) or Ethyl Alcohol at a concentration specified by the resin manufacturer. Compatible specialized cleaning solutions may also be used.
Water-washable resin should be cleaned with water or another specified cleaning medium according to the product instructions. Do not arbitrarily use the same cleaning method for different resin types.
Precautions:
Surface whitening may be caused by insufficient cleaning, residual cleaning solution, incomplete drying, abnormal curing conditions, or the material properties of the resin itself.
We recommend troubleshooting the issue as follows:
The required time depends on the resin type, model size, model structure, and equipment. Follow the recommended settings for the corresponding resin and cleaning and curing equipment.
For complex or hollow models, ensure that the interior is thoroughly cleaned and completely dry before post-curing.
Provide drainage holes in hollow models. Thoroughly clean the interior and drain any remaining resin and cleaning solution.
Ensure that both the model surface and interior are completely dry before post-curing to reduce the risk of subsequent cracking or deformation.
Collect and dispose of cleaning solutions according to the applicable Safety Data Sheet (SDS) and local waste disposal regulations.
Filtering or curing the waste liquid does not mean that it can be discharged directly into the sewage system.
