How to Make 3D Resin Coasters

Creating 3D Resin Coasters is a mesmerizing and rewarding DIY project that brings functionality and beauty to your space. Whether you're a seasoned resin artist or a beginner eager to experiment, this tutorial will guide you through every step of crafting these unique floral coasters. From selecting the right materials to achieving delicate petal designs, this guide ensures your journey is a seamless as your final creation. 

Materials & Tools You'll Need

Gathering all necessary materials before you start is crucial for a smooth crafting process. Here's your ultimate checklist:

• Table Top Epoxy Resin

• Silicone Coaster Molds

• Opaque White Pigment

• Alcohol Inks

• Mixing Cups & Stir Sticks

• Disposable Piping Bag

• Heat Gun

• Nitrile Gloves

• Respirator Mask 

• Protective Glasses

Preparing Your Workspace

A well-organized and safe workspace is key to success. Follow these tips to set up your environment:

1. Choose a Flat, Level Surface: This prevents your resin from curing unevenly. 

2. Protect Your Table: Use a plastic drop cloth or disposable table cover to catch any spills.

3. Ventilation Is Key: Work in a well-ventilated area to reduce exposure to resin fumes.

4. Maintain the Ideal Temperature: Resin cures best in a room temperature of 70-75F (21-24C)

Guide to Crafting 3D Resin Coasters

Now let's dive into the creative process. 

Step 1: Measure & Mix the Resin

Accurate measuring and mixing is critical for your coasters to cure properly.

1. Measure Equal Parts: Use a marked mixing cup to measure equal parts A and B of your epoxy resin and hardener. Follow this 1:1 ratio by volume (NOT weight). 

2. Mix Thoroughly: Stir slowly for 3-5 minutes, scraping the sides and bottom of the cup as you go. This ensures proper curing and prevents sticky spots due to poorly mixed epoxy. 

Step 2: Divide and Color the Resin

Now it's time to add color and prepare your coasters' artistic base. 

1. Separate the Resin: Divide the mixed resin into small cups, one for each color you plan to use. 

2. Add Pigments: Use epoxy alcohol inks to tint each batch. Start with a few drops and increase as needed for deeper color saturation. 

3. Mix Well: Stir each color until fully blended. 

Step 3: Prepare the White Pigmented Resin

The white resin will create the intricate flower petal effect.

1. Mix a Small Batch: Combine a small amount of resin with opaque white pigment until you achieve a thick, vibrant consistency.

2. Fill a Piping Bag: Pour the white resin into a disposable piping bag for precise application. 

Step 4: Pour the Base Layers

Here's where the magic begins. 

1. Pour the Colored Resin: Layer your colors into the silicone molds. Try creating gradients or swirling the colors for unique designs. 

2. Eliminate Bubbles: Use a heat gun or blowtorch to pop any surface bubbles. 

Step 5: Create the 3D Floral

This step brings your coasters to life with floral artistry.

1. Apply White Resin: Using the piping bag, draw your desired flower shapes onto the colored resin. Start with basic petal outlines or spirals. 

2. Refine With Tools: Use a toothpick or popsicle stick to pull the white resin outward, shaping petals or creating radial designs. 

3. Watch The Magic: As the resin settles, the white pigment will naturally sink, forming a stunning 3D effect. 

Step 6: Curing The Resin

Patience is key during this phase. 

1. Let It Rest: Allow your coasters to cure undisturbed for at least 24-48 hours. 

2. Check for Completion: The surface should be hard and free of tackiness before demolding. 

Step 7: Demolding & Finishing Touches

The final steps ensure your coasters are ready to use gift. 

1. Carefully Demold: Gently peel back the silicone mold to release your coasters without damaging the design.

2. Wipe Down: To clean off wipe it down with a paper towel and a spritz of isopropyl alcohol.
