Supplier: Prices can vary significantly between different suppliers. It is vital to compare quotes before making a purchase.
Quantity: Bulk purchases typically qualify for discounts, reducing the overall cost per unit.
Customization: Custom cuts, shapes, and finishes will add to the final price.

Cast Acrylic vs. Extruded Acrylic

The manufacturing process plays a significant role in determining the cost and properties of acrylic. Two primary methods exist:

Cast Acrylic: Produced by pouring liquid acrylic monomer into a mold and allowing it to harden. This process results in a sheet with superior optical clarity, chemical resistance, and machining capabilities. Cast acrylic is often preferred for applications requiring high precision and quality. Typically more expensive.
Extruded Acrylic: Produced by pushing molten acrylic through a die. This process results in a sheet with more consistent thickness and lower internal stresses. Extruded acrylic is often more cost-effective than cast acrylic and is suitable for general-purpose applications. Typically less expensive.

The table below illustrates the key differences:

Feature	Cast Acrylic	Extruded Acrylic
——————	—————————–	——————————-
Optical Clarity	Superior	Good
Chemical Resistance	Superior	Good
Machining	Excellent	Good
Thickness Variation	More Variation	Less Variation
Internal Stress	Lower	Higher
Cost	Higher	Lower
