Alternative uses of a 3D printer: Toner transfer on a watch dial
Alternative uses of a 3D printer: Toner transfer on a watch dial
I've watched a lot of resources about toner transfer over the last few days, and while everything was quite experimental and empirical, the main gist was : heat + pressure = toner transfer. As I didn't want to, for obvious reasons, cook a dial full of unknown glues, paints and metals in the family's kitchen oven, I started experimenting with my printer's bed.
So I made a janky setup. I printed my design mirrored on a laser-compatible transparency sheet, cut it to size, secured it on a sterile dial with a bit of Kapton and cut a bit of rubber to try and spread pressure evenly. I then clamped the contraption to my printer's heated bed.
Advantages: It's basically free if you already have a laser printer, transparencies and a 3d printer laying around.
Inconvenients: It looks absolutely unprofessional up close. At regular wrist distance, it's fine.
My first attempt was 30 minutes at 100°C. Way too much heat and/or pressure, the printing was smooshed and uneven pressure meant that parts of the design didn't transfer properly. The sheet's cutout shape was clearly imprinted on the glossy dial.
My second attempt (pictured here) was 15 minutes at 95°C. Much crisper lines and if not for a tiny bit of the logo that didn't transfer (probably a speck of dust underneath), would have been perfect. The sheet's cutout shape was still slightly imprinted on the glossy dial, on matte dials it might not be visible.
This process deserves to be refined as it brings an easy way to customize dials if you're not aiming at super macro beauty shots, unfortunately I don't have any spare dials anymore to experiment. I think a lower temperature and/or a lower pressure might work even better.
Edit: Here are my two attempts at making this dial:

Very cool! This is the second time I see the heat-bed used in an 'exotic' way 😄
But what piqued my interest is, what the heck are you doing with watch dials? I know from buying a couple of watches that the dial is always considered a work of art, precision and crispness. What I mean to say is, dials seem to be uber important. And seems very, very difficult to mimic by yourself at home.
Are you trying to create watches and thus need to also create dials? Create new dials for existing watches? I'm super curious now 😀
Here you go ;) https://lemm.ee/post/35636122
I 100% agree with you, a professionally made dial is a work of art and should be absolutely perfect at any magnification. This is just a fun, cheap summer watch project for my own enjoyment ;)
The best looking alternative would have been to have the logo made by electroforming. They look perfect and very professional. Unfortunately the MOQs are usually quite large and therefore expensive, I couldn't justify spending half the price of this project just on a logo (even if I had enough spare logos for several lifetimes).
Ah, clear. Have fun then! The end result look quite nice actually, fun project.
Thanks <3
