Watermark printing with M593 Input shaper? [obsolete]

o_lampe

I just came across the Input shaper M593.
While I studied several calibration cubes for ringing, I noticed, that I had to turn the cube to the light to see the ringing.

Why not misuse M593 to add some logo or image into the print surface!?
The method to avoid ringing is to change acceleration.(DAA)
If we'd force ringing at the right places, we could create a pattern, picture or logo. Maybe even a QR-code? Just need a preprocessor that chops a single track into various pieces and changes acc. to create the bumps.

I'm sure this could also be done by embossing the surface of the part, but that would lead to a rattling and shaking printer.
The shaper-mod would be more quiet and stealthy

//edit I just noticed that watermark is the more common word.

Not exactly, but BETTER!

I've missed a lot, when I turned my back to 3D printing...glad I came back #thankstocovidlockdown

This is from my point of view a very good example to transform a 3d printing disadvantage (layer bulges) into something positive. Maybe one can invent more such ideas. E. g. using ringing for a positive effect.
For house printers, the bulges are advantageous because walls are easier to plaster.

I played around with velocity painting, but the effect it had on a surface is minimal. At least with a 0.8mm nozzle and the yet unchanged jerk/acc and e-steps settings. There's not much information about the GUI or a tutorial for specific setup.
I guess, it's another roll of filament I'll spend until I've dialed it in.

Although their pictures in the web are quite nice.

@o_lampe nice that you're back to the 3d community. Let's discuss wire based printers

Let's discuss wire based printers

I've made an Aramid wire-driven XY plotter lately and where ever I can, I use the dual roller constrain-method to avoid racking axis'...

@o_lampe in summer I'll have to paint a wall, a wire based hangprinter would be perfect for this. I am thinking about it...

@JoergS5
Ahhh, the ** Hangprinter**!
It actually made it in the hall of fame by getting a dedicated kinematic profile in RRF.

Not sure if it can paint outside of it's own print envelop?Or do you have plans on mounting it horizontally?

JoergS5

@o_lampe the "nozzle" (the brush) can have an offset to the position - and so being outside of the construction - , so one has only to change this offset to plus/minus at the edges to get the necessary offsets. But I am currently at the idea stage, not further (no prototypes, nothing).

(not my house, unfortunately but interesting use case, to paint the correct regions, some camera data involved)

Let's get crazy and build a giant inkjet printer to spray grafitis and other Art on House Walls

JoergS5

@o_lampe that's a good idea, and then go viral and make a challenge!

Banksy! Here we come...

Back to topic...
I designed a panorama frame and tried transparent PETG. It seems, Velocity painting doesn't like Arc Welder, or pressure advance, so I switched both off and got a pretty good result.

The frame is on thingiverse
