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

Unique highly detailed fountain pens

Pjotr creates theme-based, sculpture-like fountain pens. They are entirely unique. Even in the case of copies, there is still a great variety. Every pen of Pjotr is truly one of a kind.

Pjotr’s fountain pens are theme-based. 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.
If you wish, Pjotr could put your design on this website so as to show others what Pjotr has created for you. You can even sell them copies of it, slightly different since each one is to be unique. For every copy sold, you will receive the margin you have specified in advance.

An ever increasing number of examples will soon be available on this website. Others can be viewed after making an appointment with Mr. Paul Rutte, pen specialist at P.W. Akkerman, Purveyor to the Royal Household in The Hague, The Netherlands, or Mr. Dennis van de Graaf, owner of La Couronne du Comte, located in Tilburg, The Netherlands.


A Pjotr (occasionally spelled Piotr and Pyotr) writing instrument is unique. A few of them may share a theme, but each one pen is still unique. Not just by a simple inscription, but by a distinctive element in its shape. The initials or the user’s monogram are, for instance, spaciously included, like the one depicted in the image on this page. It derives from a sailing yacht, with the letters ‘R’ and ‘M’ forming the sails.
Pjotr provides each pen with a luxurious cassette or pen case, which if desired, reflects your theme and includes your initials or monogram.

The first fountain pen made by Pjotr is in itself a brilliant collector’s item. Its theme is Cavalry. Not only the theme and elaboration are totally unique, the techniques that enable him to build it are also very challenging and highly innovative, if not to say revolutionary. The result is a remarkably detailed three-dimensional shape, in the form of a classic sculpture created by a jeweler.

Pjotr fountain pens are typically made of titanium, which makes them exceptionally light and very strong. Their average wall thickness is only 0.3 millimeter. Pens made of ceramic reinforced synthetic materials and other metals are also an option. Enamel can be applied, as well as precious stones and many other materials.

Over time, you will be able to choose from an ever increasing number of themes. The first one is already available to you: Cavalry. You can purchase it, including a three-dimensional personal touch, such as your initials or monogram.

If you have a theme in mind and you are interested, Pjotr would like to make a proposal, without any further obligation, and help you with the appearance of your future fountain pen. He can explain all about the costs involved, and how long it will take to further elaborate and create your special pen.

Explorations by Pjotr

Pjotr frequently explores the latest techniques to achieve the best possible results. This activity is named Research and consists of combinations of design and technology driven explorations with gold plated 3D printed titanium parts, 3D printed golden parts, 3D printed ceramic parts, enamel (including the plique-à-jour technique ) and gemstones.

3D Printing metal parts

The founder of Pjotr, Rein van der Mast, has joined the management team of Additive Industries. This company owns multiple state-of-art machines for printing metal parts. With these machines and several suppliers to Dutch high-tech industries Additive Industries' focus is on exploring the potential of additive manufacturing and building better printers than currently available.

Being its Manager Design & Engineering Rein is looking for ways to improve industrial productivity. He expects this to become beneficial to Pjotr.

Below is one of his latest design, a fountain pen to be 3D printed in stainless steel (316L).

More experiments

Pjotr used the abdication of HM Queen Beatrix of The Netherlands in favor of her son HRH Prince Willem-Alexander in multiple design experiments. The result shown below is camp and includes a crystal block. Inside this block there is a line 'drawn' by laser. When looking at this line from one direction one finds the silhouette of the former queen of the Netherlands. From another direction there is the silhouette of her son. The double portrait is an idea of Pieter Adriaans, artist and professor in learning and adaptive systems at the University of Amsterdam.
