Hello, this is Eureka Admin.
I recently developed Ultem feeder the titanium nib and started production.
However, I discovered a problem with the Ultem material during production and stopped it.
I knew that the Ultem material itself was not hydrophilic, but I thought it could be overcome by good structure design.
My first observation of testing the Ultem material feed, the flow was excessive at first, but after a few days the flow stabilized to some extent.
So I thought that Ultem could potentially be used as a feeder material, but it was too early to judge.
In conclusion, the hydrophilicity of Ultem was not good, so when the nib was held downward, ink dripped a certain amount.
the feeder is supposed to hold the ink, but ultem's ability to retain the ink was very poor.
I tried various surface treatment methods to improve this, but because Ultem's chemical resistance is super good, there was no groundbreaking change.
As a last resort I could try a different method, but it involves dangerous chemicals, so I gave up (at least for now).
Therefore, I decided to give up the Ultem feed project,
and instead decided to change the material to ebonite and start production again.
This is a big failure... and I was very sad, because I really liked the ultem feeder.
Fortunately though, I can retry with the ebonite material.
and hopely I can come up with a new process that can boost Ultem's hydrophilicity in the future.
It will probably take about 1~2 weeks to secure the necessary tools and materials.
I will send the Ebonite Feed to those who purchased it, free of charge, as soon as the production is initiated.
Also, all current orders will be sent with the ebonite feeder.
I apologize for any inconvenience caused by the ULTEM feeder,
and will do my best to complete the Ebonite Feed.
