Innovative 3D Printed Eyedroppers

[Driphtwood]

I know at least some of you will get a kick out of this.

What makes his creations unique is that their designs are impossible to replicate through older manufacturing methods, and if you look at some of them you'll see what I mean. Subtractive techniques like carving and machining don't cut it, and even injection molding is incapable of recreating some of what he's done.

 

The creator says that if there's enough interest, there might be purchasing opportunities in the future

I wish the person good fortune. But no interest at all.

[Moonshae]

Looks really interesting.

[Ergative]

That is incredibly cool. They remind me of this exquisite stall I saw at a craft fair once in New York, where you could buy glass flasks with separate cavities and tubes woven around each other in the main body. They wwere designed for olive oil and vinegar, and I was really tempted, but I couldn't get past the thought of how difficult they would be to clean.

 

These pens look like that. Assuming they write well (and don't cost an arm and a leg), I very well might buy one!

Very cool. I love the double helix.

When I tried to 3d print the sailor cartridge... I had issues with sealing the ink. I think they have done really well. The pens look lovely.

[basterma]

The ideas are cool. The caps look like a bit of an afterthought to me. He could have at least put a crease that echoes the spirals along the cap of the double helix pen.

Wonderful idea, I hope he develops it. And if so, I think the next step will be to visually balance the cap so that it does not seem so top heavy.

The ink reservoirs seem light and beautifully playful. I'd wonder about cleaning, though...

[Zeeppo]

Very Interesting. thank you for posting

I just subscribed to his newsletter. I like some of those designs and it appears he is trying something truly different (which this hobby needs).

 

And to give him a lot of credit: lately we've seen a lot less thought on fountain pens turn up on Kickstarter. This person is saying "hi: here's what I'm doing. What do you think?" Rather than simply announcing there's a kickstarter out of the blue. I kind of like how he is introducing himself.

I must admit to not being a demonstrator fan, but I quite like these, after all, they are pretty different, certainly different enough to be interesting.

These look really funny I hope he manufactures some, I'd definitely consider buying one.

Hello there, I am the author of Additive Pens - I found this topic by analyzing website traffic.

 

To answer some of the questions here:

- burping - I am yet to experience, but from current testing Bock nib and feed produces a very wet nib, but Jinhao feed and nib is much better behaved, surprisingly enough. Printed section may just not be precise enough. Testing ongoing!

- Polish level on par with TWSBI? It may happen for the outside, will not happen for the inside, since technology needed to achieve that does not exist yet to mu knowledge.

- The cap is a bit heavy. This is partly because of 3D printed nature I need more wall thickness than you could use with injection molding. This is area where I'd definitely want to improve. Since the spiral design is by far the most popular out there, I just might design something especially for it

- cleaning is surprisingly easy. Diamine Oxblood did stain it ever so slightly red, evenly all way round, but as long as there is any ink inside this is not visible.

 

Thank you all for kind words!

Thanks for a quick response to our questions/remarks. I will certainly keep an eye open to see how this develops.

If you can make it work so that the cap is lighter and more balanced, I'd definitely be interested...

I liked both the spiral and the spheres connected by tube design. How much ink do they hold, approximately?

I measured with a spare spiral barrel (failed print, I have A LOT of those, I call it "a bucket of shame") and it held an ungodly 5.6ml of ink. I will be re-doing the design a little bit to make it a bit shorter though, because honestly it looks a bit silly now. The connected spheres would be somewhere between 3ml and 4ml, eyeballing it. I have just one and it sits with KWZI IG Blue #2.

The pen look fun. I just signed up for the newsletter.

 

Allowing the pens to use standard Jowo or Bock units will makes them more apealing as swapping nibs is something I like to do. If they could take Pelikan M100 or M800 screw in units that would be even better (to me).

Interesting pens. But as they say, impossible is a big word that usually ends up tasting bad when eaten stale.

I don't know if you're still checking this thread, but a hybrid pen consisting of both 3D printed parts and machined parts might be the solution to all of your problems.

[SpecTP]

It seems to me that the cap could be machined to have a thinner profile instead of trying to force the 3D process to create it which doesn't seem to suit that manufacturing technique. Those are really unique and fun pens. I'd consider commissioning one.
