Yo! I’m a supplier of Resin 3D Printers, and I often get asked, "What type of resin is used for flexible prints in a Resin 3D Printer?" Well, let’s dive right into it and break down the different types of resins that are great for flexible prints. Resin 3D Printer
Understanding the Basics of Resin for 3D Printing
First off, resin 3D printing uses a liquid photopolymer resin that hardens when exposed to a specific wavelength of light, usually UV light. This process is called photopolymerization. When it comes to flexible prints, we need a resin that can bend and stretch without breaking.
Types of Resins for Flexible Prints
TPU – Thermoplastic Polyurethane Resin
TPU resin is like a superhero in the world of flexible 3D printing. It’s known for its high elasticity, which means it can stretch a whole lot and then bounce back to its original shape. This makes it perfect for creating things like phone cases, gaskets, and even small toys.
The reason TPU is so good is that it has a long molecular chain structure. These long chains can slide past each other when stretched and then go back to their original position when the force is removed. It also has good abrasion resistance, so the printed parts can withstand a bit of wear and tear.
One thing to note is that TPU resin can be a bit tricky to print with. It has a higher viscosity compared to some other resins, which means it might require a bit more care in terms of leveling the resin tank and ensuring proper flow. But once you get the hang of it, the results are really worth it.
Flexible Polyurethane Resin
Another great option is flexible polyurethane resin. This type of resin offers a good balance between flexibility and durability. It can be bent and twisted multiple times without cracking or losing its shape.
Polyurethane resin is often used for making prosthetics, soft grips for tools, and some parts of wearable devices. It has a nice tactile feel, which is great for products that are going to be in contact with the skin.
One of the advantages of flexible polyurethane resin is its ease of printing. It doesn’t have as high a viscosity as TPU resin, so it flows more easily in the printer. This makes it a good choice for beginners who want to experiment with flexible prints.
Silicone-Like Resin
Silicone-like resin gives you that soft, rubbery feel similar to real silicone. It’s highly flexible and has excellent tear strength. This type of resin is often used for making molds, art pieces that require a soft touch, and seals.
The silicone-like resin creates parts that are very smooth to the touch. It can also withstand high temperatures to some extent, which is useful if your printed parts are going to be exposed to heat. However, it can be a bit more expensive compared to other types of flexible resins.
Factors to Consider When Choosing a Resin for Flexible Prints
- Elasticity: How much the resin can stretch and return to its original shape. If you need a part that can be stretched a lot, like a rubber band, TPU or silicone-like resin might be a better choice.
- Durability: How well the part can withstand wear and tear. Polyurethane resin is a good option for parts that need to be durable.
- Printability: Some resins are easier to print with than others. If you’re just starting out, you might want to go with a more beginner-friendly resin like flexible polyurethane resin.
- Cost: The price of the resin can vary. If you’re on a tight budget, you might need to look for more affordable options.
Our Recommendations
As a Resin 3D Printer supplier, we often recommend flexible polyurethane resin for most users, especially beginners. It’s easy to work with, offers a good balance of flexibility and durability, and is relatively affordable.
For those who need parts with extreme elasticity, TPU resin is the way to go. It might take a bit more practice to print with it, but the results are amazing.
If you’re looking for that silicone-like feel and have a bit more budget to spend, silicone-like resin won’t disappoint.
Tips for Printing with Flexible Resins
- Temperature: Make sure your printing environment is at the right temperature. Some flexible resins work better at slightly higher temperatures.
- Support Structures: Use support structures wisely. Since flexible parts can move around a bit, it’s important to have proper support to ensure a successful print.
- Post-Processing: After printing, post-processing is crucial. Wash the parts thoroughly to remove any uncured resin, and then cure them under UV light for the recommended time.
