Frequently asked questions

Precious metal casting is a manufacturing process that shapes metal into detailed and intricate designs difficult to achieve by hand. The design file is 3D printed in wax, then we use the ‘tree’ casting method where multiple wax models attach to a central stem that is encased in a mould. After melting the wax, molten metal fills all cavities, creating several casts at once. Once cooled, each cast is separated and finished.

We offer casting in different precious metals, including 100% recycled 9ct and 18ct yellow, white and red, sterling silver and platinum.

We’ve designed our precious metal casting service to be as easy as possible to get your CAD designs cast and delivered straight to your door. Just upload your designs in our online portal or select one from the design library, then we’ll 3D print your design accurately in wax before casting in your chosen precious metal, to your specifications.

We also offer 3D scanning, polishing and hallmarking options to support all your needs.

Precious metal casting enables jewellery makers to produce intricate, high-quality designs efficiently and at scale. The process offers detailed customisation, durability and flexibility, making it ideal for creating unique designs. With streamlined steps from digital design to finishing options, precious metal casting provides both precision and control, ensuring each cast meets the highest standards.

Two different types of hallmarks can be applied:

Struck mark - Made with a punch and creates an impression in the item

Laser mark - Applied with a laser which will burn off the surface to create the relief

We aim to carry out struck hallmarks on items but this is subjective to the design.

It costs just £6 inc VAT (£5 exc VAT) per item to hallmark, with no minimum parcel charges and no need to post to the assay office.

Unfortunately we do not precious metal cast earring posts.

Please do not include posts when designing earrings as these cannot be printed. The length and diameter can create issues.

Instead, we suggest you attach your earring posts after you receive to your designs, we offer a range of ear pins, posts and scrolls to help you achieve this.

Here are some of our top tips for designs to ensure a smooth precious metal casting experience.

The wall thickness - Your designs need to have a minimum of 0.8mm thickness.

Ensure edges aren't too sharp- If two edges meet into a sharp point or edge they will not print very well.

Avoid small holes- Holes should be no smaller than 0.5mm.

Hollows/Multiple Pieces- Hollow pieces or interlocking pieces cannot be processed.

Watertight Models- A design must be watertight.

We accept orders for precious metal casting from customers in the UK and worldwide.

Prices are calculated based on the precious metal value and weight. Prices displayed during the order process are an estimate, and therefore there may be a small difference in price after the item has been produced, as this will be based on the actual weight of the item supplied, including sprue remnants.

If you select a polishing or hallmarking, this will also be added to the final price.

Your designs are cast, hallmarked, polished between 10–13 working days depending on your chosen polishing preference.

Prices displayed during the ordering process are an estimate only and there may be a difference between the total on the order confirmation and invoice.

Your card details will be taken during the checkout process, but payment will only be taken once your design has been cast. The final price is based on the actual weight of the metal supplied.

We do not have a minimum order quantity for precious metal casting. Whether you need a single piece or a large batch, we're here to fulfil your needs with the same level of care and attention to detail.
