Once ready, the practitioner may begin by physically marking the circle on the ground, whether by drawing it in the dirt, laying stones, or simply visualizing it in their mind. This physical representation serves as a boundary, creating a safe and sacred space where outside distractions and negative energies are kept at bay. Many practitioners invoke the elements—earth, air, fire, and water—while casting their circle, calling upon these natural forces to enhance the ritual's power and purpose.

An optimal wall thickness facilitates appropriate cooling and solidification rates, enabling high-quality parts that meet or exceed performance standards. Additionally, areas requiring enhanced strength, such as load-bearing points, can incorporate varying thicknesses tailored to specific needs, often referred to as “variable wall thickness design.”

2. Tool Preparation Once the design is finalized, tools and dies must be prepared. These tools are crafted to the specifications of the designs and are crucial for achieving the desired shape and precision in the parts. The precision of these tools directly impacts the quality of the final product.
