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

Unique highly detailed fountain pens

Pjotr 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 (designer and technologist Rein van der Mast) 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.

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

State-of-the-art

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. It is the first 3D printed fountain pen in the world, revealed in 2013.

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

Pjotr provides each pen with a luxurious 3D printed, highly unique cassette or pen case.

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.”

More Design Research

To explore more of the potential of 3D printing related to fountain pens I tried a DIY (Do-It-Yourself) 3D printer, one made by in Holland by Ultimaker. And applied a bronze filled filament from ColorFabb. More on the website of ColorFabb:

Also included is the latest version of my additvely manufactured fountain pen nib (patent pending), world's first !

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."

Spica Virginis, titanium 3D printed fountain pen and nib

DORDRRECHT, The Netherlands – November 23, 2016 – The Dutch designer and technologist Rein van der Mast is about to disrupt how fountain pens are made. Instead of relying on proven technology like turning, a couple of years ago he started 3D printing titanium fountain pens and now he also 3D prints  its fully functional nib. This enables him to create complex design features and even mechanical assemblies in a single 3D print.

Early in 2013 the first 3D printed fountain pen was revealed by Pjotr, the artist name of Rein van der Mast. After more than three years, required to overcome various technological challenges, there is now the Spica Virginis, resembling a spike of wheat and named after the brightest star in the constellation Virgo, where the virgin holds a bundle of spikes.

Aerospace and automotive

Shortly after Van der Mast had introduced the first 3D printed fountain pen ever made he became the Manager Design & Engineering of a Dutch start-up called Additive Industries. Today this company has sold several of its impressive machines. Its clients are well known firms in aerospace and automotive. There he was able to extend his skills in additive manufacturing, another term for 3D printing. Van der Mast: “In case of the Spica Virginis design has priority over technology. Back in 2013 it was the other way around.” To demonstrate the potential of 3D printing in customization he started with one of a kind designs. Van der Mast: “Having only one piece to carry the design effort results in a pricey object.” So today his goal is to create small series. Each piece however has its unique serial number included in the 3D print.

Printed nib

Van der Mast also 3D printed the pen’s nib. “It is amazing what one can create by 3D printing. The nib is printed in titanium with the slit included. The current model is rather straight forward. This way however I can create very complex ink channels and precisely affect the way the nib interacts with the paper as well as the pen's user. And of course, this way one can also create very complex shapes for esthetic reasons.” The results stimulated him to convert his effort into a patent application.

Creating an object virtually and digitally enables its designer to test it before it is made physically, saving time and costs. So Pjotr put his 3D printed titanium nib (patent pending) into Inspire 2017 of Altair and ran this simple test. In the animation above one can see areas with tension (orange) and compression (green). Slight modifications in the nib’s design will have different results, enabling the designer to modify the nib's ‘flex’ in detail.

Also the pen case is extraordinary. Its structure is very complex and called a ‘lattice’. Structures like this are only feasible by 3D printing. Common benefits are in better stiffness-to-weight ratio. "And it is only getting better as more machines enter the marked for fabricating smaller objects more precisely."
