Beyond a pen

By chance I came across a rather unusual student project from Finland’s Aalto Univeristy. It is called Beyond a pen and looks at mass produced pens, their stories and more.

The EGO.M Cento 3 – a graphene pencil

A few weeks ago I received a surprise parcel from John Hall of Write Here fame. Inside the parcel were two rather unusual pens that I have been using regularly since then. It’s time to send them back soon, but before I do that I want to show you these very special pens and talk about their unusual design.

You can also find a video about the Cento3 on the Bleistift Youtube channel:

The mystery of a pen body made from graphene

Let’s get their most exotic property out of the way first: these pens are 3d printed from graphene. With graphene not being very think (one layer of atoms) you could think of it as being two-dimensional. You also commonly read that a one atom thick layer of graphite is graphene. With that in mind I am wondering how something three-dimensional can be graphene without turning into graphite. Maybe it is a flat ‘two-dimensional’ layer rolled up with some other material in between, but in that case, does it keep graphene’s properties and are they desirable in a pen body in the first place? So many questions….

I also wonder whether creating the Cento3 pen body requires very special 3d printers so that the graphene layers don’t melt together into a lump of graphite and whether the body has some sort of lacquer on top. Whatever the answers to all my questions are, the pen that Ego.M have produced is a very special pen and as I don’t understand enough about materials science I will just go along with the claim that this pen is made from graphene.

The design’s history

The idea for this pen was thought up 20 years ago, in 2001, when Achille Castiglione and Gianfranco Cavaglia came up with a pen design using the ‘trilobate’ shape. Think of three slim pens arranged together like a three-leaved clover and connected – I hope the image below gives you a better idea than my short description.

I hope this image give an idea how the ‘trilobate’ shape is being used for this pen. (click to enlarge)

At the time some non-working prototypes were made from wood, but the pen was not commercially produced until recently when the prototypes were rediscovered by the designer’s children and EGO.M, based in Bologna, started developing the prototypes into commercially produced pens which were then officially released in February 2021, 103 years (100 = Cento, so Cento3 = 103) after Achille Castiglione was born.

About the pen

Surface

The first thing most people will notice when they look at this pen is that the individual strands of extruded plastic filament are quite visible. On the body of the mechanical pencil I received for testing the pattern produced by the 3d printing process is much less ‘even’ than on the lead holder I got. I assume every pen is unique in this respect and if you pick another sample this might be different, i.e. another mechanical pencil might look ‘smoother’ and another lead holder might look less smooth. The uneven surface loves to attract dust which is quite visible if you enlarge the photos.

Weight

The next thing to notice is that for their length and diameter the Cento3 pens are quite light. In the diagram below you can see that compared to some of the mechanical pencils we looked at in the past only slim and plastic-y mechanical pencils and tiny mechanical pencils are lighter than the Cento3 mechanical pencil.

Amateurs like me often like heavy pens as they give the user the feeling of being more substantial and of higher quality, but professionals actually like light pens. It makes sense to use a light pen that isn’t tiring when you use it all day long.

Mechanism and ageing

I was not able to figure out what kind of mechanism is used in the mechanical pencil as I don’t see a non-destructive way of getting to the mechanism. I assume the 3d printing of the body is done directly on the mechanism.

Pens change over time. One example is the beautiful surface of the Lamy 2000. Over time it becomes more and more smooth and shiny. I am not sure how hard the filament is that was used to print the Cento3, but there is a good chance that over the years the surface might become more and more smooth. This is just a guess, but it might change the character of he pen over time.

The weight and shape make the pen surprisingly comfortable to hold and use. The 3d printed structure provides a good grip when you hold the mechanical pencil. Many mechanical pencil users rotate the pen automatically and even subconsciously to make the lead use up more evenly. This is slightly more difficult with the Cento3 compared to a thinner pen, but it is possible without hassle.

The lead holder

In my opinion the lead holder version of the Cento3 feels much posher than the mechanical pencil. Maybe it is down to the chrome-y front section or the more even printing of the filaments.

Conclusion

These pens are a great innovation. They are not the first 3d printed pens available, but the first ones I know of with the graphene link. The mechanical pencil sells for £60, as does the lead holder. There’s also a fountain pen version for £80.

Thanks to John for lending me these for my blog post and video.

Please note that the pen is properly black, I just lit it so that you can see the surface well which made it looks less black on my photos than it actually is.

A Danish Noris

The Staedtler Noris can regularly be seen in news reports here in the UK (stock footage of school kids often include scenes of children writing with a Noris because of its popularity in schools) …so normally a Noris in the news (BBC or otherwise) wouldn’t be worth mentioning. Today is different though: because of a football (soccer) game between England and Denmark this evening the BBC News at Six viewers got a rare glimpse of what is going on on the streets in Copenhagen.

Unlike here in the UK, where the ‘normal’ hexagonal Staedtler Noris is most popular, this unrepresentative sample of one from Denmark seems to suggest that the Noris Triplus Jumbo, which is not a common sight in the UK, is more common in the land of Hygge.

The Lamy exact – older than the Lamy 2000

Unfortunately work didn’t leave me much spare time so I didn’t get round to finishing the Cento3 graphene pencil blog post yet, but with the previous blog post here being four weeks old I thought it’s time for a quick ‘Bleistift is still alive’ post.

Today I want to show you a fifty year old advert for the Lamy exact and some other Lamy pens, including the Lamy 2000. At the time the Lamy 2000 was about five years old.

This advert is currently being sold on eBay and is listed as being from 1971.

I have translated the text for you:

You may be able to afford illegible handwriting, but not an unclean one.
Leave the cleanliness of your handwriting to LAMY exact. The ballpoint pen with the perfect technology and functional design.
Its large capacity refill with a stainless steel tip guarantees a problem-free 10,000 m writing line. With a single
refill you will write evenly and cleanly for at least a year.
Every time you click this refill ready for writing, it turns by 120 degrees. Like this it cannot be worn down on one side only, cannot blot, cannot smudge. Additionally, the ‘signal marker’ indicates whether the refill is extended.
In short, any advantage that is imaginable for a ballpoint pen – the LAMY exact has it. For an always clean and
exact handwriting.
You can find the LAMY exact range with large capacity refill in leading stationery stores.


In the price list the Lamy 2000 range is being referred to as ‘The manly range’. The more affordable Lamy design 20 range is being referred to as “The young range’.

For reference: In 1971 10 DM were equivalent to 3 US Dollars or £1.20.

According to Lamy’s history page the Lamy exact came out in 1964 and was Germany’s first ballpoint pen with a large capacity refill.

I plan to add information from this advert to Stationery.wiki’s Lamy page.
