3D Printed Kaweco Al Sport Clip

Recommended Posts

Actually it is the first posts of this account.(Although I collected pen for long time, I never resgister on FPN before)

I use an advanced 3d scanner and then draw its stl file for 3d printing. Actually it match Kaweco Sport Pen.

Then I asked for a modern industrial 3d printed machine to build it. The material is CoCrMo Stellite alloy.

However, I didn't have good tools to polish so it looks very rough.

You can download STL file here:

Suggestion:

Use metal printing at first. I try PA66, PA12 before but the strength is not enough.

Polishing is the most important process, without good polishment it may hurt Kaweco Pen Body

How's the durability, even with the sintered metal printing? :)

 

 

I dunno... clip of that design I think it's made that way to be able to be cheaply & easily manufactured by stamping out of sheet steel and being bent.

 

When designing something for print-manufacture... I always hope for something more innovative than just apeing current existing conventions.

Pretty cool! That saves a little bit of $, if you scale that up you could make some cool stuff. Caught an article in pen world about someone making 3d printed pens, can't remember the name right now but you could try that. Seems like a complicated undertaking but if you can make some nice pens with the correct housing and such a very rewarding one as well.

 

Good luck with your 3d printing in the future! :)

After all It is Stellite alloy. If you dont bend this clip by brute force for many times, its performance must be better than original Kaweco Clip

Thanks a lot! I have draw a pen file already. It doesn't matter if it is failed to printed. I can also convert to CAD format so it can be used in CNC maching.

Stellite is cobalt-based, meant for wear & corrosion resistance...?

Which I usually read as "hard & brittle", wouldn't be improved by sintering.

 

How's that compared to Spring Steel?

Have you modelled the whole pen? :)

 

Truth be told, I've got a Kaweco Sport and Pilot Kakuno sitting next to be 3D workbench for inspiration. Wondering what's a neat way to mod them for a clip or something else... add-on accessories are already out there but don't really match the pens.

 

Been thinking I should model (or get said model) the whole cap & then mod that for integrated clip.

Sorry for replying so late,

 

1 For CoCrMo, if you use annealing process, it will provide better toughness compare to some Unannealed spring steel. But it still lack elasticity compare to those top high quality spring steel with perfect annealing. I choose this material because it won't rust in most general enviroment.

2 Actually, a friend of mine has made a whole titanium pen so I directly buy it from him.

3 Use or lend a professional 3d scanner and convert it to stl file. But to be honest, Clip may be not suitable for Pilot Kakuno, because I also try to build a 3d file for it but the cap has to many curved area. Beside it also has a small pen stop so an extra clip may looks very strange. As for Kaweco, a cheaper way is to measure one side length of the hexagon cap and then draw a standard hexagon as the clip Cross section. To meet the clip match perfectly. You can also expand this hexagon 0.1mm or 0.2mm so that the clip can fit surface better. Integrated clip is ok, but it may be harder to repaired.

Hey if someone wants to replicate the whole pen, but instead use the longer barrel of the delike alpha (it's about 1cm longer with a rounded bottom so it can be used unposted and accepts a proper converter) out of titanium or brass or copper or bronze, I'd buy the heck out of one.

Does the Delike use the same threads as Kaweco? like are the barrels & lids interchangeable?

 

Would love it if everything was modular, one could use barrel & cap of different materials etc.

What would be achieving that isn't in your delike?

My delike is just a little rougher on the finish. It's a storied old beast by now, but I do worry that in 15-30 years it might not survive. I'd prefer one with a plastic sleeve to prevent scratching and metal on metal for the threads.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..
    • A Smug Dill
      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
