Premium Mould #13 - 3D Printed Insert Holder Mould

A common rule of thumb in the plastics industry is: “The higher the quality of the mould, the higher the quality of the final product.”

That’s why we created our Premium Moulds range. These moulds are machined from solid Aluminium to ensure the highest quality surface finish and are designed specifically for the capabilities of our machines. They are the best choice for creating high-detail, useful products from recycled plastic.

Design your own product and injection mould it from recycled plastic. The 3D Printed Insert Holder Mould is a precision machined aluminium frame that accepts custom 3D printed resin inserts, letting you create any shape you can design. Available in four sizes to suit a wide range of products, from small accessories to larger functional parts.

Variants / Sizes

• Small: 30mm x 50mm x 50mm insert space. Best suited for small accessories, tokens, and jewellery.

• Medium: 50mm x 75mm x 75mm insert space. A versatile mid range size for handles, cases, and small household items.

• Large: 50mm x 100mm x 100mm insert space. Suited for larger functional parts and multi-component designs.

• XLarge: 50mm x 150mm x 100mm insert space. The largest frame in the range, for bigger products and deeper parts.

Guides on how to design and print your resin inserts are available on our Resources page.

Production at a Glance

Less than 2 minutes per cycle. Output depends on your insert design and the number of cavities you build into it.

The compatible plastic type depends on the resin used to print your inserts. Common options include PP, HDPE, LDPE, and PLA. Check our Resources page for guidance on resin and plastic compatibility. The Injection Mini Machine is the recommended machine for 3D printed inserts, as its precise pressure control helps protect the resin cavity during injection.

Perfect For

• Product designers and engineers prototyping new injection moulded parts without the cost of a dedicated mould

• Small businesses testing new product ideas in recycled plastic before committing to a full production mould

• Schools and universities teaching mould design, 3D printing, and injection moulding in a single hands on workflow
