Have you ever looked at an everyday object and thought, “I could make a mold of that”? That’s the beauty of art – finding inspiration in unexpected places. In this post, we’ll take you on a step-by-step journey of how I, Robert Kline, transformed a humble peanut into a virtual mold using the magic of 3D modeling, ultimately turning it into a unique, hand-crafted candle.
The Inspiration: A Nutty Idea Takes Shape
As artists, we often find inspiration in the world around us. This time, it was a simple peanut. Its organic shape and textured surface sparked an idea – could I capture its essence in a virtual mold and create something unique? Thus began my virtual mold-making adventure.
Bringing the Peanut into the Virtual World: Photogrammetry
Before we dive into the virtual mold making, let’s talk about how I got the 3D model of the peanut. The answer lies in a fascinating technique called photogrammetry. This process involves taking multiple photographs of an object from different angles and using specialized software to stitch them together, creating a detailed 3D model. You can learn more about my photogrammetry workflow in a previous post.
3D Modeling Magic: Creating the Virtual Mold in Blender
With my peanut digitized and ready to go, it was time to fire up Blender, my 3D modeling software of choice, and embark on the virtual mold making process.
1. Setting the Stage: Importing and Preparing the Model
The first step was to import the peanut’s STL file into Blender. Once imported, I made sure the model’s origin was set correctly, which is crucial for maintaining symmetry and alignment throughout the process.
2. Scaling Reality: Adjusting the Peanut’s Dimensions
My digital peanut was a bit larger than life (or at least larger than the real peanut!). Using Blender’s scaling tools, I resized the model to my desired dimensions, which would translate to the final size of my candle.
3. A Smooth Operator: Remeshing for a Flawless Surface
Before creating the mold, I needed to ensure the peanut’s surface was watertight and free of any imperfections. Applying a ‘Remesh’ modifier in Blender helped me achieve a smooth and refined model, ready for mold creation.
4. Building the Virtual Mold: Subtracting the Peanut
Now for the exciting part! To create the mold, I introduced a cylinder shape into the scene. Using a Boolean modifier, I subtracted the peanut model from the cylinder, effectively carving out a negative space within the cylinder. This negative space would become the mold cavity.
5. Splitting the Mold: Preparing for Real-World Casting
For easy casting, I split the virtual mold into two halves using a plane object and the trusty Boolean modifier. This step ensures easy demolding after the casting material has set.
From Virtual to Reality: 3D Printing and Candle Making
With the virtual mold complete, I exported it as an STL file and brought it to life using my 3D printer. The printed mold served as a perfect negative form for casting my candles.
For this project, I experimented with different waxes and even incorporated a wick through a cleverly designed channel in the mold. The result? Unique, peanut-shaped candles with intricate details that captured the essence of the original peanut.
Robert Kline Art: Embracing the DIY Spirit
Creating virtual molds opens up a world of possibilities for artists and makers. It allows us to translate digital designs into tangible objects, replicating intricate details and organic shapes with precision.
Remember, the key is to embrace experimentation and not be afraid to explore new techniques. Who knows what everyday object might inspire your next masterpiece?
