Resin 3D printing has become one of the most advanced and popular technologies in the world of additive manufacturing. Its ability to create parts with fine details and smooth surfaces makes it ideal for a wide range of applications. However, a common question among users is: how long does resin last in 3D printing? In this article, We will explore resin durability, associated costs and other key aspects of its use in 3D printing.
Before you start: Key considerations for Resin 3D printing
How long does resin last in 3D printing?
The lifetime of resin in 3D printing depends on several factors, such as the type of resin used, the storage environment and usage. In general, the resin has a shelf life of approximately 12 months if stored under optimal conditionsThe product should be stored in a cool, dark place and in a well-sealed container.
Is it economical to use photo-reactive resins in 3D printing?
Photo-reactive resins can be more expensive than other 3D printing materials, but their high quality and precision justify the price. In addition, the efficiency and ability to produce detailed and complex parts can offset the initial cost.
How strong is 3D printing resin?
The strength of 3D printing resin varies depending on its formulation. Some resins are designed to be extremely hard and impact resistant, while others are more flexible and elastic. In general, modern resins can offer strength comparable to many thermoplastics, making them suitable for functional applications and prototypes.
How much does a resin 3D printer spend?
The resin consumption of a 3D printer depends on the volume of the parts being printed. For example, a printer can consume between 50 and 100 ml of resin for a small part. It is crucial to optimise resin usage to minimise waste and reduce costs.
How many parts can I print with 1 litre of resin?
The number of parts that can be printed with 1 litre of resin depends on the size and complexity of each part. On average, about 10 to 20 small parts or several large parts can be printed with one litre of resin.
Resin maintenance and preservation
Proper maintenance of resins is essential to ensure durability and quality. Store the resin in a cool, dark place, and be sure to shake it well before use. It is also important to clean and maintain the printer regularly to avoid contamination and malfunction.
How long does a litre of 3D printer resin last?
The lifetime of a litre of resin depends on the volume and frequency of printing. For an average user who prints occasionally, one litre of resin can last several months. However, for intensive use, you may need to replenish the resin more frequently.
What types of resins are there?
The resins used in 3D printing vary according to their properties and applications. Among the most common types are:
- Standard resin: Ideal for prototypes and decorative parts.
- Dental resins or biocompatible resins: Used in dentistry for their safety and precision.
- Industrial resin: Calcinable and with high chemical, mechanical and thermal resistance.
- Flexible resins: They offer elasticity and are suitable for parts that require some flexibility.
What are the strongest 3D printing resins?
There are a number of resins on the market that offer exceptional strength. Some of the most prominent are high hardness resins and resins with advanced mechanical properties such as impact and high temperature resistance.
First steps: A simple guide on how to 3D print with resin from setup to post-processing.
The process of 3D printing with resin:
- Printer calibration
Before you start printing, it is crucial to calibrate your resin printer correctly. Follow these steps:
- Leveling of the base: Remove the resin tank and make sure there is no resin residue. Place a sheet of paper over the LCD glass and adjust the print base until it is completely parallel to the screen surface.
- Adjustment of the base: Loosen the screws of the printing base, place the paper sheet and tighten the screws again making sure that the base is aligned.
- Resin preparation and filling
Before pouring the resin, wear gloves and have isopropyl alcohol on hand to clean up any spills. Fill the resin tank to the indicated level, without exceeding the maximum mark.
Once the printer is calibrated and filled, load the print file into the laminator and adjust the parameters according to the resin manufacturer's specifications.
- Peel off the prints
Peeling the model off the printing base can be tricky. Use a spatula with a plastic blade to avoid scratching the base. A mini clay modelling trowel can also be useful, especially if it is thin and flexible.
- Post-processing: washing and curing
After printing, the models are covered with sticky resin that must be removed. Follow these steps:
- WashingWash the part in an isopropyl alcohol bath. You can use a washing machine that rotates the part 360 degrees for best results. Replace the alcohol regularly to maintain washing efficiency.
- CuringInsert the washed part into a curing machine so that the light is applied evenly, ensuring that the resin is fully cured.
Tips to avoid resin 3D printing failures
- Accurate calibration: Careful printer calibration is essential for accurate prints.
- Regular maintenance: Clean and maintain your printer regularly to avoid contamination that can affect print quality.
- Parameter optimisation: Adjust the printing parameters according to the type of resin and the model to be printed to obtain the best results.
How to correctly configure resins in additive manufacturing
Correct printer and resin setup is critical for best results. This includes calibration of exposure time and temperature, as well as adjustment of the printing platform to ensure proper adhesion of the layers.
How to optimise a resin when 3D printing
Optimising resin usage involves adjusting parameters such as light exposure, layer height and print orientation. These adjustments not only improve the quality of the prints, but also reduce resin consumption.
