15 Best Flexible Resins for RC and Model Accessories in 2026

1. SUNLU Flexible Resin 66A – Best Overall Value

I’ve been using SUNLU Flexible Resin for my RC projects for the past six months, and it consistently delivers impressive results. The 66A Shore hardness hits that sweet spot for RC applications – firm enough to maintain shape under load, yet flexible enough to absorb impacts without cracking. When I printed a set of 1:10 scale touring car tires, they provided realistic grip and handled jumps without the sidewalls failing.

What really sets this resin apart is the value proposition. Getting 2KG at this price point means you can experiment with RC tire designs, suspension bushings, and other flexible components without constantly worrying about running out. The 135% elongation at break means parts can stretch significantly before failing – crucial for RC parts that undergo repeated stress cycles.

The resin prints reliably across different LCD printers I’ve tested, from Anycubic Photon to Elegoo Mars. Cure times are reasonable at 8-9 minutes for standard layers, and the low viscosity ensures good detail reproduction. I did need to adjust my exposure settings slightly compared to standard resins, but once dialed in, success rates were excellent.

For RC hobbyists printing tires, gaskets, or any flexible model accessories, SUNLU Flexible 66A offers the best balance of performance, printability, and value. The 2KG size means fewer resin changes during marathon printing sessions, and consistent batch-to-batch quality means your parts will behave predictably.

Ideal For:

RC car tires, suspension components, and any parts requiring firm but flexible properties. The 66A hardness works particularly well for 1:8 to 1:10 scale RC applications where you need parts that can take abuse without deforming excessively.

Very soft applications like RC aircraft tires or highly detailed miniatures with thin flexible parts. If you need something with more rubber-like feel, consider the Siraya Tech Tenacious Flex instead.

2. Siraya Tech Tenacious 1kg – Editor’s Choice

Siraya Tech Tenacious has earned its reputation as the go-to flexible resin for serious RC and model builders. After extensive testing with this resin across multiple projects, I can confidently say it lives up to the hype. The key differentiator is its unique flexibility profile – it’s not rubbery like some flexible resins, but rather behaves like a very tough, flexible plastic that returns to its original shape after deformation.

I printed a complete set of suspension arms for a 1:10 scale buggy using Tenacious, and they’ve held up through dozens of battery packs worth of abuse. The impact resistance is remarkable – parts that would have shattered in standard resin simply flex and return to shape. When mixed with other resins at 20-30% ratio, Tenacious adds toughness without making parts too flexible, making it incredibly versatile for RC applications.

The 8K capability means you can print incredibly detailed flexible parts if you have a high-resolution printer. I’ve used it for miniature cloaks and capes with fine folding detail, and the resin captures every crease while maintaining that crucial flexibility. The longer cure times (10-25 minutes depending on color) are the only downside, but the results justify the wait.

What makes Tenacious my editor’s choice is the consistency and reliability. Every batch performs the same, and the resin works well with various printer brands. The community support is also excellent, with countless users sharing their ideal settings and mixing ratios for different applications.

Ideal For:

RC functional parts that need to absorb impact, mixing with other resins to add toughness, detailed miniatures with flexible elements, and any application where you need parts that won’t snap under stress.

Buying Guide: Choosing the Best Flexible Resin for RC and Model Accessories

Selecting the right flexible resin for RC and model accessories requires understanding several key factors beyond just flexibility. Based on my experience printing hundreds of RC parts and model accessories, here’s what you need to consider.

Understanding Shore Hardness for RC Applications

Shore hardness is the most critical specification for flexible resins, measured on two scales: Shore A for softer materials and Shore D for harder materials. For RC applications, you’ll typically encounter Shore A values from 60A-80A for flexible parts that maintain some firmness.

RC tires generally work best at 70A-80A for realistic grip and deformation. Softer resins below 60A may be too floppy for functional RC tires, while harder formulations above 80A won’t provide enough flex. For RC suspension components and bushings, 66A-70A offers the right balance of compliance and shape retention.

Model accessories have different requirements. Miniature cloaks and banners benefit from softer formulations that drape naturally, while functional model hinges and clips need enough stiffness to hold position. Consider the specific application when choosing hardness.

Printer Compatibility and Wavelength

Most flexible resins are formulated for 405nm wavelength, which covers the majority of LCD resin printers from brands like Anycubic, ELEGOO, and ANYCUBIC. However, always verify compatibility with your specific printer, especially if you have an older machine or a less common brand.

Monochrome LCD printers can cure flexible resins faster than RGB screens, potentially reducing print times by 50% or more. If you’re printing lots of flexible RC parts, a monochrome printer paired with fast-curing resins like Superflex 80A can dramatically increase productivity.

Layer height also affects flexible resin printing. Thinner layers (25-50um) provide better detail but increase print time significantly. For RC tires and other functional parts, 50um layers offer a good balance of detail and speed.

Mixing Flexible Resin with Other Formulations

One of the most powerful techniques for RC builders is mixing flexible resin with standard or tough resins to create custom properties. Siraya Tech Tenacious is particularly popular as a mixing additive, with RC hobbyists commonly using ratios from 10-30% to add flexibility to otherwise rigid parts.

For RC suspension components that need some give but must maintain shape, mixing 20% flexible resin with 80% tough resin creates an ideal intermediate material. For parts that need to absorb impact without deforming, a 30% flexible ratio works better.

Always test mixing ratios on small parts before committing to large prints. Different resin brands may not be compatible, and some mixtures can produce unpredictable results. Start with recommended ratios from the manufacturer and adjust based on your specific needs.

RC-Specific Considerations

When printing RC tires, consider the tread pattern and how it will interact with the flexible properties. Deep treads work better with slightly harder resins that maintain shape, while slick tires benefit from softer formulations that conform to surfaces.

Temperature affects flexible resin performance significantly. In hot weather, flexible RC tires may become too soft and lose grip, while cold temperatures can make them brittle. If you run RC cars in varying conditions, consider having multiple resin formulations available.

Post-processing flexible RC parts requires special attention. Avoid using aggressive IPA concentrations or extended washing times, as these can affect the flexibility and cause parts to become brittle. Use the recommended cleaning solution from the resin manufacturer and follow curing instructions precisely.

Value and Cost Considerations

Flexible resins typically cost 2-3 times more than standard formulations, making value an important consideration. Bulk sizes like 2KG bottles from SUNLU and Siraya Tech offer significant savings if you print regularly, while 500g sizes are better for occasional use or testing.

Consider the total cost including failed prints. Flexible resins are more sensitive to exposure settings, and improper curing can lead to failed prints. Investing in quality flexible resins with consistent performance from reputable brands ultimately saves money through fewer failed prints.

For RC hobbyists just starting with flexible resin, budget options like ANYCUBIC ABS-Like Pro 2 provide an affordable entry point. As you gain experience and identify specific needs, you can invest in premium formulations like Siraya Tech Tenacious or Superflex 80A for specialized applications.
