If you are looking for a material that moves like silicone but is less expensive in small batches than traditional molding, 3D printed elastic resin is a great option. The material stretches, bends, and bounces back like a rubber band, but is also tough enough to handle production needs.
It is the answer to prototyping and producing parts that need the flexibility of silicone without the hassle of traditional molding. If you’re curious about how this material can enhance your next project, this guide explores its properties, uses, and practical considerations.
What Is Elastic Resin?
Elastic Resin, officially termed Elastic 50A Resin, is a material made to replicate the features of silicone. Most 3D printing materials are rigid, but this type of resin acts more like an elastomer. This means it’s stretchy, compressible, and resilient. It’s shore hardness is 50A, which is the pliability of a certain type of silicone.
You can use this material for any product that needs elasticity, such as wearables, medical devices, and soft-touch parts. It is tear-resistant, shatterproof, and able to be bent without losing its shape.
Why Choose Elastic Resin?
If you have ever dealt with silicone manufacturing, you know how expensive it can be. If you decide to go the route of traditional methods like injection molding, be prepared to pay a hefty upfront cost for tooling and plenty of time for production. If you’re running a small business or experimenting with new ideas, those costs can be the reason you decide against a project.
The best thing about elastic Resin is that it bridges the gap between prototyping and production. Think of it like a trial run for your product. With Elastic 50a Resin, you can quickly print a working prototype, test its durability, tweak the design if needed, and repeat the process. It’s a budget-friendly, time-saving alternative. Elastic Resin enables fast, cost-effective prototyping to test and refine designs before committing to final production.It’s perfect for anyone who wants to experiment with silicone-like materials but isn’t quite ready for the commitment of traditional molding.
Popular Applications of Elastic Resin
Elastic Resins work great for a range of industries. Here are just a few applications to show you what it is capable of:
1. Medical Prototypes and Models
This 3D printed material is changing the medical field as we know it since it offers a cost-effective way to create lifelike models.
- Patient-Specific Models: You can 3D print an exact replica of a patient’s anatomy. Surgeons can use these custom models to plan complex procedures, practice techniques, and improve surgical outcomes.
- Educational Models: Medical schools can create transparent, flexible models of organs, muscles, and joints to help students better understand anatomy and function. The softness of Elastic Resin mimics how tissues stretch, bend, or compress under pressure.
2. Consumer Goods Prototyping
If you are designing wearables or soft-touch gadgets, this material makes it easy to prototype products that feel as good as they look.
- Wearables: From fitness bands to smartwatch straps, Elastic Resin lets you test the fit, feel, and functionality of your designs before moving to production.
- Soft-Touch Features: Perfect for products with tactile elements, like ergonomic grips, buttons, or textured surfaces. This allows designers to refine the touch and performance of their products without waiting for costly silicone molds.
- Kids’ Products: Small businesses creating safe toys or baby gear can use the material to test usability and safety.
3. Robotics
In robotics, you can create components that are both flexible and functional.
- Compliant Features: Its softness and stretchability make it great for parts that need to move. Soft robotic grippers or bumpers are a couple of things that come to mind.
- Shock Absorption: You can use this material for cushioning parts for robots that need to withstand impacts.
4. Special Effects and Props
Hollywood and cosplay can use this resin to create special effects.
- Realistic Props: Need a squishy, stretchy texture for a creature effect or costume? Elastic resin can mimic skin, tendons, or other organic forms beautifully.
- Wearable Effects: Create masks, gloves, or other wearable pieces that move with the actor’s body, offering comfort and believability.
- Prosthetics for Acting: For roles requiring highly detailed prosthetics, it gives the realism and flexibility needed for movement and performance.
Working With Elastic Resin
Like any specialized material, this resin has some unique considerations. Here’s how to make the most out of it:
Design Tips
If you are working with the material, keep this in mind:
- Optimize Support Structures: It needs sturdy supports during printing to prevent sagging or deformation. Aim for supports that are connected well. Also make sure to avoid isolated ones that are longer than 20 mm. This will minimize your risk of print failures.
- Design for Self-Support: Whenever possible, try to create models with features that can support themselves. This keeps the complex support structures and post-processing simpler. For example, gradually sloped surfaces and reinforced edges can help your design stay stable during printing.
Post-Processing Best Practices
There are also some things to keep in mind when post-processing:
- Washing: Making sure you wash your creation well is one of the most important steps. Start with a 10-minute wash on the build platform, followed by another 10-minute wash in fresh solvent. Be careful not to exceed 20 minutes total, as overexposure to solvents can degrade the material’s elasticity and texture.
- Curing: Post-curing is critical for maximizing strength and durability. Use a UV curing station made for this material. Also make sure you follow the recommended exposure times to keep your parts flexible.
Limitations to Keep in Mind
There are also some limitations you should know about if you decide to choose this resin:
- Not Ideal for High-Detail Prints: Elastic 50a resin is great for flexibility, but might not be your best choice for s design with detail. If precision is key, a more rigid resin might be better suited to your project.
- Softer Than Flexible Resin: It is softer and stretchier than flexible resin, which means it can require additional support during printing and careful handling during post-processing to avoid damage.
- Structural Demands: Because of its softness, it may not work well for parts that need to keep rigid forms.
Exploring Beyond Prototyping
Elastic Resin works great for prototyping, but it can also be used for the production of final parts. For businesses aiming to create niche products or test small-scale manufacturing, this material provides a fast, cost-effective option.
Short-Run Production Made Simple
This resin allows businesses to produce a limited quantity of finished parts quickly and cost-effectively. This material provides a low-risk way to explore production without the financial or logistical challenges of traditional manufacturing.
- Customizable Designs: Elastic Resin’s ease of use with SLA printers means you can customize designs quickly, perfect for small-batch runs tailored to specific customer needs or preferences.
- Reduced Time to Market: It enables rapid production, letting businesses pivot or adapt to customer feedback faster.
Testing Small-Scale Manufacturing
For businesses exploring manufacturing on a smaller scale, it is an awesome tool in several ways:
- Market Testing: You can test who interested a customer is in a product without committing to a full production run.
- Limited Edition Runs: It also works great for exclusive or seasonal products in small quantities. You can charge premium pricing and still get that high customer engagement.
As you can see, it is a bridge between ideation and small-scale production. It empowers businesses to experiment, innovate, and deliver niche products with confidence.
Final Thoughts
Elastic Resin is a gateway to faster innovation, cost savings, and expanded creativity. If you’re designing the next breakthrough in wearable technology or crafting realistic props for the big screen, it offers the flexibility to bring your vision to life.
