Introduction
Resin prints are a popular form of 3D printing that use resin instead of traditional filaments. While they offer many benefits such as high precision and intricate details, they do require some extra steps to achieve a polished finish. Sanding resin prints is one such step that can help remove the rough texture and create a smooth and flawless surface.
In this article, we’ll provide you with all the information you need to know about sanding resin prints. From the types of sandpaper to use, to step-by-step instructions, common mistakes to avoid, and expert tips for achieving a professional finish, this ultimate guide has got you covered.
The Ultimate Guide to Sanding Resin Prints: Tips and Tricks to Achieve a Smooth Finish
Types of Sandpaper and Their Uses
Before we jump into the sanding process, let’s first take a look at the different types of sandpaper and their uses. There are three main types of sandpaper:
– Coarse sandpaper (60-100 grit) – best for removing excess resin, smoothing rough edges, and shaping the prints.
– Medium sandpaper (120-150 grit) – ideal for smoothing out the rough surface left by coarse sandpaper.
– Fine sandpaper (220-400 grit) – used for final polishing and creating a smooth surface.
It’s important to start with coarse sandpaper and work your way up to finer grits to achieve the desired finish. Using too fine of sandpaper too early in the process can actually clog the sandpaper and slow down the sanding process.
Step-by-Step Guide to Sanding Resin Prints
Now that we know the different types of sandpaper, let’s dive into the step-by-step process of sanding resin prints.
1. Start by wearing gloves and a mask. Resin dust can be harmful if inhaled, so it’s important to protect yourself.
2. Begin by sanding with coarse sandpaper (60-100 grit) to remove any excess resin and shape the print as desired.
3. Move on to medium sandpaper (120-150 grit) to smooth out the rough surface left by the coarse sandpaper.
4. Finally, use fine sandpaper (220-400 grit) for final polishing and to achieve a smooth surface.
5. Rinse the print with water to remove any sanding residue, and dry it with a cloth.
6. If desired, you can apply a polish to the print using a soft cloth and polishing compound.
List of Materials Needed for Sanding
To get started with sanding resin prints, you’ll need the following materials:
– Various grits of sandpaper (60-100 grit, 120-150 grit, and 220-400 grit)
– Gloves
– Mask
– Water
– Cloth
– Polishing compound (optional)
Tips for Achieving a Polished Finish
Here are some tips to keep in mind when sanding resin prints to achieve a polished finish:
– Sand in a well-ventilated area or wear a mask to avoid inhaling resin dust.
– Use a light touch when sanding to avoid removing too much material.
– Move the sandpaper in a circular motion to prevent creating flat surfaces.
– Avoid using too high of grit sandpaper too early in the process to prevent clogging the sandpaper.
– Rinse the print between sanding grits to remove any residue.

Experimenting with Sanding Resin Prints: Achieving Unique Aesthetics
Examples of Designs and Patterns That Are Possible with Sanding Techniques
Sanding resin prints can be a way to achieve unique designs and patterns. Sanding at different angles, for example, can create a matte finish that contrasts nicely with the glossy surfaces. Patterns can also be carved into the resin by hand, creating unique and intricate designs.
Tips for Achieving Unique Designs with Sanding
To achieve unique designs with sanding, experiment with sanding at different angles and using different levels of pressure. You can also try carving patterns into the resin by hand using a sharp tool.
Sanding Resin Prints for Functional Objects
Explanation of How Sanding Can be Useful in Creating Functional Objects
While sanding is often thought of as a decorative technique, it can also be useful in creating functional objects such as cups and bowls. Sanding the bottom of a cup, for example, can create a smooth surface that won’t scratch or damage surfaces.
Tutorials and Tips for Sanding Functional Items Such as Cups and Bowls
To get started with sanding functional objects, start with coarse sandpaper to shape and remove excess resin. Then, move on to finer grit sandpapers to achieve a smooth surface. Be sure to sand the bottom of the cup or bowl to create a smooth, non-scratch surface.
