Who it fits

RI Resione F80 Key Specs

Shore Hardness: 50-60A

This rating measures how soft the cured material feels. A value between 50A and 60A indicates a flexible, rubber-like texture. You can press into the surface, and it will bounce back quickly. This makes it ideal for parts that need to bend or absorb shock. Standard rigid resins feel hard and brittle. Choose this if you need gaskets, seals, or soft-touch grips that withstand repeated deformation without cracking.

Curing Wavelength: 405nm

This number tells you which light frequency hardens the resin. A 405nm wavelength matches the standard UV LEDs found in most LCD and MSLA 3D printers. You do not need special equipment to use this product. It works with both RGB and mono screens. If your printer uses 385nm or 405nm lights, this resin will cure properly. Always check your printer manual to confirm the LED output before starting a print job.

Size: 1000g

This specification defines the total volume of resin in the bottle. You receive one kilogram of material, which is a standard amount for testing or small projects. This size allows you to print several medium-sized flexible parts. If you need more material for large batches, you can buy the 500g option separately. The 1000g size offers a balanced starting point without requiring you to mix multiple small bottles for a single large print.

Color: Black

This indicates the pigment added to the liquid resin. The black color provides a neutral, professional look for finished prototypes. It helps hide layer lines better than lighter shades. You can also choose pink if you need dental gingival models, as that color is standard in that industry. Black is versatile for toy tires, shoe samples, and general elastic parts. The pigment does not affect the flexibility or curing speed of the material.

Design and Build Details

According to the listing, this resin comes in a 1000g container. The black option is the specific variant reviewed here, though a pink color is also available. You choose between 1000g and 500g sizes depending on your project volume. The packaging weighs 2.2 pounds. This weight reflects the density of the liquid resin. You should plan your workspace to handle this mass safely.

The material is formulated for 405nm curing wavelengths. This matches the light source in most mainstream LCD and MSLA printers. You do not need special hardware to use it. The resin works with both RGB and Mono screens. This broad adaptability means you can switch printers without changing materials. The design focuses on compatibility rather than unique hardware features.

The build quality centers on the cured part's properties. The Shore hardness sits between 50A and 60A. This creates a soft, elastic finish. The prints recover their shape quickly after deformation. This resilience is key for functional parts. You can use these prints for seals, buffers, or toy tires. The material remains soft even below 10°C, though elasticity drops slightly. The design supports flexible applications without complex post-processing requirements.

Setup And Daily Use Guide

Setup involves preparing your resin tank for a flexible material. The RI Resione F80 Flexible Resin 1kg cures at a 405nm wavelength. This matches the light source of most mainstream LCD, MSLA, and DLP printers. You can use it with both RGB and Mono screen models. The listing confirms broad adaptability to these standard technologies. No special hardware adjustments are noted for compatibility. You simply load the black resin into your printer’s vat.

Everyday use focuses on its elastic properties. The material has a Shore hardness of 50-60A. This means prints feel soft to the touch. They possess good resilience, recovering their shape quickly after deformation. This makes the resin suitable for making toy tires, shoe samples, seals, and buffers. You can also create various elastic prototypes that require a rubber-like finish. The black color is practical for these functional parts.

Temperature plays a role in daily handling. Even in cold environments below 10°C, the prints remain soft. However, you should note that elasticity decreases as temperatures drop. This is a physical property of the cured resin, not a printing error. The 1kg size provides ample material for multiple small projects. You can also choose a 500g option if your needs are smaller. The process remains consistent with standard resin printing workflows, aside from the unique flexibility of the final part.

Before You Buy This Resin

Owning the RI Resione F80 requires specific post-processing habits. Flexible prints often stick more firmly to build plates, so you may need a PEI sheet or specialized release agents to ensure clean removal without tearing. Because the material retains elasticity, washing and UV curing times might differ from rigid resins. You should verify your printer’s screen compatibility, as the listing states it works with LCD, MSLA, and DLP models using 405nm light. However, performance can shift in cold environments below 10°C, where elasticity decreases. Keep your workspace warm for consistent results. This resin fits alongside rigid options for projects needing shock absorption, like seals or toy tires. It complements your existing tools by adding a new material category to your workflow. Check if your current filtration system handles flexible residues effectively, as they can clog filters faster than standard materials.

Check before you buy

• Confirm your printer uses 405nm curing light sources.
• Check if your build plate handles flexible adhesion.
• Ensure your workspace stays above 10°C for best results.
• Verify PEI sheets or release agents are available.
• Check if your filter system handles flexible residues.
