Creator of the first 3D printed fountain pen in the world

Unique highly detailed fountain pens

Pjotr by Rein van der Mast creates small series and single pieces of sculpture-like fountain pens using state-of-the-art technologies like high grade software and additive manufacturing (3D printing in metals).

Pjotr is designer and technologist Rein van der Mast. He likes you to devise the theme you like best. And then, with your approval, he generates a true sculpture that matches your theme, digitally at first and tangibly in the end. This always results in a striking collector’s item, as well as an outstanding and appealing piece of writing equipment.

He also likes you consider his limited editions, having each pen uniquely numbered and a design that has no equal.


Pjotr by Rein van der Mast fountain pens are typically made of titanium, which makes them exceptionally light and very strong. Other metals, including gold as well as ceramics are also available to additive manufacturing (3D printing in metals).

Rein van der Mast is also the inventor of the addively manufacured or 3D printed fountain pen nib (patent pending). All his pens are equiped with this nib. It performs very well.

ROTTERDAM, The Netherlands – Rein van der Mast very pleased to announce the TypeONE, an affordable 3D printed fountain pen that is equipped with the world’s first 3D printed titanium nib.

The pen is brought to the market by 3Dimensions: a partnership of Dennis van de Graaf, owner of the renowned fountain pen shop La Couronne du Comte, Bart Koster, owner of Promo2000 and pen distributor, and Rein van der Mast, creator of the world's first 3D printed fountain pen (2013) and nib (2016).

18K Solid Gold 3D Printed Fountain Pen & Nib

ROTTERDAM, The Netherlands – The Dutch designer and technologist Rein van der Mast is disrupting how fountain pens are made. Instead of relying on proven technology, in 2013 he started 3D printing titanium fountain pens and nibs. Today he started 3D printing both in 18K solid yellow and white gold.

There is the Spica Virginis, his latest design, resembling an ear of grain and named after the brightest star in the constellation Virgo, where in ancient drawings the virgin holds a bundle of grain ears. In 18K yellow gold the color perfectly matches the color of grain.

The pen is also available in 18K solid white gold. Van der Mast: “This type of white gold is developed for 3D printing, selective laser melting in particular. It is very white, and more important, it is very hard, eliminating the need for a rhodium coating.” He emphasizes that this is particularly useful for nibs. Van der Mast is the only one in the world 3D printing nibs and holds a patent application on it.

Van der Mast: “For people who prefer the lightness of titanium, which is less than 1/3 of the density of gold, we offer our titanium version plated with a thick layer of 24K gold with a tiny amount of cobalt for better wear resistance.”

First review of the 3D printed titanium nib

A beta version of the Spica Virginis was tested by Dries Bleus. About the nib:
"The medium-broad nib is ground to a stub and it writes like a dream. Being titanium, it offers a good amount of bounce, and some line variation if necessary. The feed provides a generous flow and keeps up well."
