Etching Press Aims To Impress

There’s an old joke about inviting somebody up to your dorm room to ‘look at your etchings’ — but if you’re going to do that, you’d best have some etchings, lest they call your bluff. Even better would be to have prints available, so you might share your hard work with adoring fans. Over on YouTube, [This Designed That] shows building the perfect little etching press  so you need never invite anyone to your room again: you can crank out enough prints on this bad boy to hand out your etchings on a street corner!

Crank is the right word, because it’s hand-cranked, with the rollers chain-driven off a separate driveshaft. It works like, well, a roller press: two steel rollers squeeze a platen holding your inked etching and a of paper together to put an image onto. His choice of an off-cut of steel pipe to use as the top roller is inspired, even if he did have to turn it down quite a bit to get an even radius and smooth surface finish. The whole thing is very well made, and all of it hand-machined except for off-the-shelf bearings and the yellow side plates, which were commercially CNC’d.

We also appreciate that [This Designed That] took the time to prove the merit of his machine by showing the press in work, and the resulting prints.  We’re not art critics, but we are willing to say this makes a good impression.

[This Designed That] is both printer and machinist, and we’ve seen his print projects before, like using resin prints for foil stamping or a DIY proofing press that seems to share some DNA with this larger project.

3D Printing A Printing Press

If you move among artists, you may have encountered a few printmakers. They create a drawing by cutting through a wax layer that has been deposited on a sheet of copper, then etching the plate and removing the wax. Ink is then rolled onto the plate and cleaned from the flat surface, remaining in the cracks created by the etching. A print is made by putting inked plate and a sheet of paper through a roller press at significant pressure, squeezing the ink from the cracks onto the paper. The result is a beautiful print, but the press required to do the job is by no means cheap.

[Martin Schneider] has addressed this expense with his Open Press project, by producing a printmaking press that can be 3D-printed for a fraction of the outlay of a traditional press. It’s by no means a large model, but appears no less functional for it.

The form of the press is straightforward enough, with a print bed that is drawn between a pair of rollers by a rack-and-pinion gear, and as you would imagine the construction is quite substantial. It’s all CC licensed, and you can make one for yourself if you would like, by downloading the files from Thingiverse.

It’s fair to say that printmaking hasn’t appeared much here, but we can see this press could have significant use beyond artistic applications. Meanwhile it’s a great example of 3D printing providing the means to reduce the barrier to entry for something that was previously quite an expensive pursuit.
