3D printing has become increasingly popular in recent years, as it allows users to create custom objects with relative ease. One of the most popular types of 3D printing is resin printing, which uses a liquid resin that is cured by ultraviolet light to create solid objects. Resin printing is often used to create highly detailed miniatures, such as those used in tabletop gaming.
However, resin printing can be a challenging process, and it is important to understand the proper techniques in order to achieve the best results. One of the most important factors in resin printing is the preparation of the model. The model must be properly scaled and oriented in order to ensure that it prints correctly. Additionally, the model must be supported by scaffolding, which will help to prevent it from warping or collapsing during the printing process.
Once the model is prepared, it is time to begin the printing process. The printer will use a laser to cure the resin, one layer at a time. The printing time will vary depending on the size and complexity of the model. Once the printing process is complete, the model must be post-processed. This involves removing the supports and cleaning the model with isopropyl alcohol. The model can then be primed and painted as desired.
1. Preparation
Preparation is a crucial step in the 3D resin printing process, as it ensures that the model will print correctly and with the desired quality. Scaling the model to the appropriate size is important to ensure that it fits within the build volume of the printer and that it has the desired dimensions. Orientation is also important, as it affects how the model is supported during printing and how the layers are bonded together. Finally, supports are essential for preventing the model from warping or collapsing during printing, especially for models with overhangs or delicate features.
For example, if a model is not properly scaled, it may be too large to fit within the build volume of the printer, or it may be too small and difficult to see the details. If a model is not properly oriented, it may be difficult to print certain features, or the supports may not be able to adequately support the model. Finally, if a model does not have proper supports, it may warp or collapse during printing, resulting in a failed print.
By understanding the importance of preparation and following the proper steps, you can increase your chances of successfully printing high-quality 3D resin minis.
2. Printing
In the context of 3D resin printing, printing is the process of converting a digital model into a physical object. The printer must be calibrated correctly in order to ensure that the model is printed with the desired accuracy and precision. The printing speed and layer height must also be carefully controlled in order to achieve the best possible results.
-
Calibration
Printer calibration is the process of ensuring that the printer is functioning properly and is able to produce accurate prints. This involves checking the printer’s settings, such as the nozzle temperature and bed leveling, and making sure that the printer is properly aligned. Regular calibration is essential for maintaining the printer’s performance and ensuring that prints are of the highest quality.
-
Printing Speed
The printing speed is the rate at which the printer extrudes the resin. The printing speed must be carefully controlled in order to achieve the best possible results. If the printing speed is too fast, the resin may not have enough time to cure properly, resulting in a weak or brittle print. If the printing speed is too slow, the print may take too long to complete and may be more susceptible to warping or other defects.
-
Layer Height
The layer height is the thickness of each layer of resin that is deposited by the printer. The layer height must be carefully controlled in order to achieve the best possible results. If the layer height is too thick, the print may be rough and have visible layer lines. If the layer height is too thin, the print may be more fragile and may be more likely to warp or fail.
By understanding the importance of printing and by following the proper steps to calibrate the printer and control the printing speed and layer height, you can increase your chances of successfully printing high-quality 3D resin minis.
3. Post-processing
Post-processing is a crucial step in the 3D resin printing process, as it ensures that the model has the desired surface finish and mechanical properties. Removing the supports is important to free the model from any scaffolding that was used to support it during printing. Cleaning the model is important to remove any uncured resin that may be on the surface of the model. Curing the model under ultraviolet light is important to fully cure the resin and give the model its final properties.
-
Removing the Supports
Supports are essential for preventing the model from warping or collapsing during printing, but they must be removed after printing is complete. Supports can be removed by hand using a hobby knife or pliers, or they can be dissolved using a solvent such as isopropyl alcohol. It is important to remove the supports carefully to avoid damaging the model.
-
Cleaning the Model
After the supports have been removed, the model must be cleaned to remove any uncured resin that may be on the surface. Uncured resin can be removed by rinsing the model in isopropyl alcohol or another suitable solvent. It is important to rinse the model thoroughly to remove all of the uncured resin.
-
Curing the Model
After the model has been cleaned, it must be cured under ultraviolet light to fully cure the resin. Curing can be done using a UV lamp or by placing the model in direct sunlight. The curing time will vary depending on the type of resin used and the thickness of the model. It is important to cure the model for the correct amount of time to ensure that the resin is fully cured and has the desired properties.
By understanding the importance of post-processing and by following the proper steps to remove the supports, clean the model, and cure the model under ultraviolet light, you can increase your chances of successfully printing high-quality 3D resin minis.
FAQs on “How To Properly Print 3D Resin Minis”
This section addresses common questions and concerns related to 3D resin printing, providing concise and informative answers to guide users towards successful printing experiences.
Question 1: What is the ideal room temperature for resin printing?
Answer: Maintaining a room temperature between 20-25 degrees Celsius (68-77 degrees Fahrenheit) is recommended for optimal resin printing conditions. This temperature range ensures proper resin flow and curing, minimizing the risk of printing failures.
Question 2: Why is it crucial to wear a respirator during resin printing?
Answer: Resin fumes emitted during the printing process can be harmful if inhaled. Wearing a respirator with appropriate filters (e.g., organic vapor cartridges) is essential to protect the respiratory system from these fumes.
Question 3: How can I improve the adhesion of the printed model to the build plate?
Answer: Ensuring a clean build plate surface, applying an adhesion promoter, and properly leveling the build plate are key factors in enhancing adhesion. Additionally, using a raft or brim in the print settings can provide extra support for the model during printing.
Question 4: What is the purpose of post-curing resin prints?
Answer: Post-curing exposes the printed model to additional ultraviolet (UV) light, further strengthening the resin’s molecular structure. This process enhances the model’s durability, surface finish, and resistance to wear and tear.
Question 5: How can I troubleshoot printing issues related to layer separation?
Answer: Layer separation can occur due to insufficient UV exposure or improper resin settings. Calibrating the printer’s UV intensity and adjusting print settings, such as layer thickness and exposure time, can help resolve these issues.
Question 6: What are the storage considerations for resin and printed models?
Answer: Store resin in a cool, dark place away from direct sunlight to prevent premature curing. Keep printed models away from excessive heat and UV light to maintain their integrity and prevent yellowing.
