SUNLU Standard Resin Key Specs

Net Weight: 1kg

This value indicates the amount of liquid resin you receive in the container. You get exactly one kilogram of material for your printing projects. This size is practical for beginners who want to test the resin without committing to large volumes. It allows you to produce several medium-sized models before needing a refill. Larger sizes are available if you print frequently.

Material Type: Photopolymer Resin

This specification confirms the chemical nature of the fluid. You are buying a photopolymer resin that hardens when exposed to specific light sources. This type of material is essential for LCD, DLP, and SLA printers. It differs from filament-based materials used in FDM printers. Understanding this helps you ensure your printer uses the correct technology for this supply.

Curing Wavelength: 405nm

This number defines the light frequency required to harden the resin. A 405nm wavelength is the industry standard for most resin printers. It ensures compatibility with nearly all current LCD and DLP machines on the market. You do not need to worry about mismatched light sources. This standard value makes the resin a safe choice for new printer owners.

Surface Finish: Smooth

This attribute describes the texture of the cured print. A smooth finish means the printed parts have minimal layer lines and a clean appearance. You will spend less time sanding or polishing after the print is complete. This quality is ideal for miniatures or detailed models where surface detail matters. It provides a professional look right after the post-curing process.

Design and Build Overview

According to the listing, SUNLU Standard 1kg UV Resin is a photopolymer resin designed for LCD, DLP, and SLA 3D printers. The packaging is a rectangular container measuring 4.96 inches in length, 2.09 inches in width, and 9.15 inches in height. This compact footprint allows you to store the bottle easily on a shelf or in a printer cabinet without taking up excessive space. The total shipping weight is 2.2 pounds, which includes the liquid content and the container itself. This weight distribution suggests a sturdy bottle that is manageable for most users to handle during pouring and cleanup.

The resin itself is classified as a standard material type with a smooth surface finish. You can expect the printed parts to have a hard and smooth texture, which makes post-processing easier. The listing notes that the surface is easy to color after printing, allowing for customization if needed. The bottle comes in various colors, including clear, white, black, and gray, though the specific variant you choose does not change the physical build of the container. The design prioritizes functionality, with a focus on easy cleaning using isopropyl alcohol or ethanol. This practical approach means you can maintain a clean workspace with minimal effort, keeping your printing environment organized and safe for repeated use.

Setup And Daily Use

This resin is designed for straightforward integration into your existing workflow. You do not need special hardware to use it. The listing states it works with LCD, DLP, and SLA printers. It cures at wavelengths from 365 to 405nm. This range covers 99% of machines on the market. You can load the resin into your printer’s vat without modification. The material has strong fluidity. This property allows it to flow easily during printing. It supports various printing speeds. This flexibility helps you adjust settings without issues. The resin is suitable for novices who are learning the process. It forms parts easily. During the curing stage, the resin exhibits low shrinkage. This feature helps maintain accurate size and shape for your printed objects. The material also shows good stability against weak acids and greases. Your prints will not deform easily. This makes the resin reliable for general manufacturing needs. Cleaning is simple. You can use isopropyl alcohol or ethanol to remove excess resin. The surface finish is smooth and hard. This texture makes post-processing easy. You can color the parts after printing with minimal effort. The listing notes that the odor is light. This balance minimizes potential discomfort during use. The product is available in multiple sizes and colors. You can choose between clear, black, white, and other shades. The 1kg container is practical for testing. It allows you to evaluate the material before committing to larger volumes.

Before You Buy This Resin

You need to prepare your workspace before opening this container. Standard photopolymer resin requires proper ventilation. The listing notes minimal odor, but you should still work in a well-ventilated area. You will need isopropyl alcohol or ethanol for cleaning. These solvents remove uncured resin from printed parts and the build plate. Ensure your printer supports wavelengths between 365 and 405nm. This resin fits 99% of LCD, DLP, and SLA machines. Check your printer’s specifications to confirm compatibility. This product is suitable for novices due to its easy fluidity. It offers good stability against weak acids and greases. You can post-process the smooth surface by coloring or sanding. Compare this option with other standard resins on the page. It provides accurate size and shape with low shrinkage. This makes it reliable for detailed models. It is a practical choice for limited budgets. You get one kilogram of material for your projects.

Check before you buy

• Verify your printer supports 365 to 405nm UV light.
• Ensure you have isopropyl alcohol or ethanol for cleaning.
• Check that your workspace has adequate ventilation.
