Once again we’re proud to announce a new member in our growing family of 3D printing materials and finishes! This time we would like to introduce the official trial of a shiny new metal finish: Chrome-Plated Brass! Featuring a smooth and glossy surface, a great level of detail, and a razor-thin electroplated chromium layer, this finish is what many of you have been waiting for. Let’s take a closer look!
Introducing 3D Printed Chrome-Plated Brass
As of today, you will be able to get your design 3D printed in Chrome-Plated Brass with i.materialise. The finish has now officially debuted as a new trial 3D printing finish for Brass on our website.
Models made out of Chrome-Plated Brass are constructed based on a wax 3D print, a casted brass object, and electroplating treatment (we’ll tell you more about the technique later). This leads to a real metal piece with a stunning chrome look!
This mix of 3D printing, casting and electroplating leads to a smooth surface, high level of detail and a great shine! The chrome-plated layer offers a polished aesthetic appeal, provides some corrosion resistance and increases the surface hardness of your model. It is a more affordable imitator of chrome and its aesthetics. This makes Chrome-Plated Brass perfect for decorative items such as car parts and tools.

The Technology behind Chrome-Plated Brass
Wax 3D printing and lost wax casting are used to build your design when using Brass for your model and finish. This means that a wax 3D print of your model will be printed first and used to create a mold. The wax will then be burned out of the mold and liquid brass will be poured into the cavities that are left behind.
The finishing is done manually: to get the Chrome look, a very thin layer of copper will first be applied to your model, followed by a layer of nickel, which acts as a base that the chromium will attach itself to. We then apply the chromium layer in the final step.
Design Guidelines for Chrome-Plated Brass
If you are already familiar with our Brass design guide there is good news: the guidelines for Chrome-Plated Brass are just the same as those for our other finishes. In a nutshell, you should try to stick to the following rules:
- Choose a minimum wall thickness of 0.6 mm. If you intend to print a wire structure, your walls should be at least 1 mm thick.
- Make sure that small decorative parts and embossed/engraved text have a size of at least 0.35 mm.
- Keep in mind that the maximum size of your object can be up to 88 x 63 x 125 mm.
- If you want to print a hollow model, make sure to add several release holes (we recommend adding at least three holes with a diameter of at least 1.5 mm)
- Keep in mind that you cannot upload grouped models and interlocking parts in this material/finish.
You can find the complete list of these design rules with more explanation and imagery in our Brass Design Guide.
