Below is the platform I used to learn how to build this website and others.
Thanks for the interesting article on techniques for model making and making intricate craft molds. You mention 3D printers becoming more popular and being used. Do you think that the art of making molds and models and even sculpting the traditional way will be lost as technology can easily mass produce models? I think now a days the masses don’t really appreciate the time and effort that goes into an artwork. I’d love to hear your opinion. I used to decorate cakes and all my designs were made by hand. I didn’t use shaped cake pans but carved the cakes by hand. My figurines were sculpted by hand and time consuming. I even made my own molds so I could get the right design but some potential customers didn’t appreciate skill and time involved in the work.
Hi Lyn,
Thank you for your comments and questions. 3D printers are a huge advancement, so yes many of the true methods of model making may disappear, but a new one is born because it is no easy task to draw and render the new type designs/models on a computer.
Many years ago I saw my first true model makers in a foundry environment where we were making parts for the auto industry and models were made to form patterns in the hand-packed sand before pouring the molten metal.

Hi!
This is a very interesting article! I think the art of making molds is very cool and I appreciate the talent of the artist. I had a favorite sculptor that made Christmas ornaments. He used to release one new design every year. He was a local guy that I would see at craft shows. His health declined as he got older and closed his business. I really miss his work, but I get to think of him every Christmas when I decorate my tree.
Your post is a fantastic deep dive into advanced model-making techniques! The breakdown of materials, sculpting methods, and reinforcement strategies is especially helpful for anyone looking to refine their craft. The section on leveraging 3D printing is particularly intriguing—combining traditional and digital techniques really seems to be the future of precision modeling.
When working with multi-part molds, what’s the best way to minimize visible seams in the final casting?
