Velocity Painting (ish :) without the software

This is nervoussystem’s 2-color tree frog from 2-color tree frog by nervoussystem - Thingiverse

It’s meant to be printed as a two-colour dual-extrusion, but instead I:

  • dropped the two parts (colour 1 is one part, colour 2 is the other) into Simplify3D
  • aligned the two part origins (as printing them side-by-side wouldn’t cut it :slight_smile:
  • set a low print speed for the main part and a high speed for the other

…and a bazillion retractions later (not pleasant on a delta), this appeared.

The effect is optically subtle, but textually unsubtle (it’s wrinkled! Think frog/prune hybrid). Not as effective a full #VelocityPainting but still a useful technique to keep at the back of your mind?

13mm/s low speed #3Dprinting 35mm/s high speed. @Faberdashery_Ltd Orange Fizz PLA.

The Velocity Painting project is at GitHub - MarkWheadon/velocity-painting: #VelocityPainting: patterning 3D prints by modulating the print speed should you wish to get involved or simply keep an eye on developments.

I see that you are a backer of the Polymaker Polysher, how do you think that smoothing a Velocity Painted object would look?I realize that I’m asking for some speculation here.

I have a feeling that it will make it much more subtle. On the other hand Polymaker say that not much surface detail is lost (unlike acetone vapour smoothing for example), so maybe the detail that is left will really stand out on the super-glossy surface.

I guess I’ll find out eventually! It’s possible that the PVB filament will behave differently even before it’s smoothed…

Thanks!We’ll have to wait and see. Maybe Polymaker will have a go while we are waiting,they can’t have anything better to be getting on with :slight_smile:

@Mark_Wheadon ​ after viewing the readme on git it states that #velocitypainting is only in a state that a programmer could use it… I would love to give it a shot can you point me. In the direction of any tutorials that would help me get started with the learning curve?

Aah always the programmer who get to play with cool stuff first :slight_smile:

Well having the programming skills should have some perks associated with it, right? :wink:

@Alex_Krause A tricky question to answer, which is why I haven’t answered it! Maybe other people could have some input here?

@Kevin_Blackburn Close – I printed it at 150nm.

@Kevin_Blackburn I find that it’s not the detail that suffers at higher layer heights (well, not particularly) as it only affects Z, mainly it’s the horrible stepping you get on prints like this with near-horizontal surfaces, so prints without near-horizontal surfaces often look pretty fine at 200nm, but models like this look like they have strangely symmetrical wood-grain :smiley:
