Trying something new
My partner got into candle making and it sparked (pun intended) my curiosity. Have you ever bought a product online and it didn't quite live up to your expectations? That's exactly what happened to my partner when she purchased several moulds for candle making. Although advertised as candle moulds, they turned out to be more suited for soap making and therefore impractical for their intended use.
As someone who enjoys a good DIY project, I decided to take matters into my own hands and find a solution to our problem. Having previously watched various videos on the topic of silicone mould making, I began researching how to make a silicone mould based on a 3D printed object. To my surprise, the process seemed fairly straightforward.
First, I needed to create a 3D model of the candle I wanted to make. But as a short cut for this first attempt I downloaded the Twisted Heart Vase by Gyorobot and printed it using our 3D printer. Next, I needed to create a box to contain the silicone while it cured, which I made using cardboard, a trimmed down water bottle and hot glue.
After that, I mixed the PINKYSIL® – fast set silicone and poured it into the box, making sure to cover the 3D printed object completely. The silicone then needed to cure for an hour before it was ready to use. Once cured, I removed the 3D printed object from the silicone mould, and it was ready to use for candle making.
Not only was this a fun and easy DIY project, but it also solved our problem of impractical candle moulds. By using a 3D printed object to create a custom silicone mould, we were able to make candles that fit our specific needs and preferences. So, if you ever find yourself in a similar situation, don't be afraid to get creative and try out some DIY solutions!
PS. Maybe this particular shape didn't make for the most practical candle because it has a large undercut. Lesson learned.
