Who it fits

Key specs explained

Shore Hardness 70A

This rating defines the material's firmness on the Shore A scale. A 70A value indicates a rubber-like texture that bends easily but retains its shape. You get parts that feel soft to the touch yet remain durable. This level of flexibility suits wearable items or gaskets. It differs from rigid resins that snap under stress. Choose this spec if you need comfort and bendability in your final prints.

Resin Type Flexible

This classification tells you the material is engineered for elasticity rather than rigidity. Flexible resins absorb impact and withstand repeated bending without cracking. This makes them ideal for phone cases, hinges, or tool grips. Standard resins often fail when subjected to similar mechanical stress. Select this type when your project requires parts that can deform and return to their original form safely.

Net Weight 1kg

This figure represents the actual amount of resin inside the container. A 1kg net weight helps you estimate print volume and layer counts. You can calculate how many small or large objects a single bottle yields. This standard size fits most resin tanks without excessive weight. It allows for manageable handling during the pouring and cleaning processes. Use this data to plan your material usage for upcoming projects.

Printing Technology Resin

This indicates the material is liquid photopolymer cured by light. You must use a resin 3D printer, such as an LCD or DLP model, to print this. It is not compatible with filament-based FDM printers. Resin technology typically offers higher detail and smoother surface finishes than filament. This spec confirms you need a vat printer and proper ventilation. Ensure your equipment supports liquid resin workflows before purchasing.

Design and Build Quality

The listing specifies a 1kg net weight for the resin, which corresponds to a total package weight of 2.2 pounds. You receive the material in a black, 1KG size container. The bottle features a leak-proof design with a tight airbag wrap. This packaging choice aims to prevent breaks or spills during transit. You do not need to worry about messy leaks when handling the unit. The container itself is described as secure, ensuring the resin remains intact until you are ready to use it.

According to the listing, the resin delivers a smooth, non-sticky finish. You get a clean, dry surface feel straight from the printer. This characteristic means you will not deal with tackiness or dust retention on your printed parts. The material is noted for low viscosity, which supports better flow during the printing process. This property likely aids in consistent layer adhesion for your flexible projects. The product also claims low odor, suggesting a more pleasant workspace environment compared to stronger-smelling alternatives.

The build quality is defined by its rubber-like elasticity and exceptional tear resistance. You can expect parts that withstand repeated bending, twisting, and compression without deforming. This durability ensures that thin or detailed sections will not rip easily. The design is built for long-term use in moving or wearable applications. The material retains its shape while offering comfort and bendability. You get a robust solution for functional prototypes that require both flexibility and structural integrity.

Setup And Everyday Use Guide

This resin is designed for resin-based 3D printers. You do not need to mix it with other materials before printing. The low viscosity specification means the fluid flows easily through the printer’s delivery system. This property helps ensure consistent layer adhesion and reduces the chance of clogs during the printing process. You can load the 1kg bottle directly into your machine’s reservoir. The leak-proof packaging with its tight airbag wrap protects the material during transit, keeping it fresh until you are ready to use it. In daily operation, the low odor feature allows for a more pleasant workspace environment. This makes it suitable for indoor settings where ventilation might be limited, though standard safety precautions still apply. The Shore 70A hardness rating indicates a rubber-like elasticity. You will find this ideal for creating parts that require comfort and bendability. The material withstands repeated bending, twisting, and compression without permanent deformation. This makes it well-suited for wearable items or components with moving parts. The smooth, non-sticky finish emerges directly from the printer. You will not encounter tackiness or dust retention on the surface. This clean, dry feel simplifies post-processing. You can handle the prints immediately after curing without worrying about residue. The enhanced tear resistance ensures that even thin or detailed sections remain durable. You can expect long-term performance from these prints, as they are built to resist ripping under stress. This combination of easy flow and flexible durability supports efficient everyday use for various functional prototypes.

Before You Buy This Resin

You should verify that your resin printer supports flexible materials before purchasing this Inslogic product. Flexible resins often require slower print speeds and adjusted exposure times compared to standard UV-curable liquids. You must ensure your printer’s build plate adheres well to soft materials, as standard PEI sheets may struggle with the initial layers of Shore 70A resin. Consider acquiring a dedicated spatula for peeling, as flexible parts can stick more tenaciously to the FEP film. This 1kg bottle fits neatly into most standard resin storage areas, but you need airtight containers to prevent premature curing from ambient light. This material complements the other options in 3D Printers & Making Tools by offering a unique tactile experience. While other listings focus on rigid durability or high-temperature resistance, this black resin provides rubber-like elasticity. You get a distinct workflow that prioritizes bendability over structural stiffness. Proper ventilation remains essential due to the low odor, though it is not odorless. Store the bottle upright in a cool, dark place to maintain its low viscosity and printing consistency.

Check before you buy

• Check if your printer supports flexible resin settings.
• Verify build plate adhesion for soft materials.
• Ensure you have airtight storage containers.
• Confirm compatible post-curing equipment is available.
