I'm studying 3D recently, and I'm enjoying your video. Please upload a lot in the future. Thank you for the great video. I'll learn and do my best! ^-^
Great tutorial, Ryo! The trick with Merge by Distance to reduce the excess of points of the Fillet Curve solve my problem here. Regarding the #frame driver, I use another alternative: I plug the Scene Time (frames) to the Map Range and set the From Min to 1 and From Max to whatever I want. I think this is a quicker way of changing the animation duration
Thanks, this was really helpful! How would you reverse the print direction, for example in a 3D structure with a continuous print path, how would you tell it that the path start is at the bottom? (currently my animation is printing top down)
There are many ways to do this. Just off the top of my head, you could animate the Start value of the Trim Curve node, rather than the End value. Connect the Floored Modulo to the Start input rather than the End. You'll need to flip the output from the Modulo (it current goes from 0 -> 1 as the frame count progresses. We want it to go 1 -> 0 instead). Drop a Map Range between Floored Modulo and Trim Curve. Set the to min/max to 1 and 0. Hit play, the print should appear from the other end
Hi Ryo, I have a cube design, but after adding the floored modulo and value and play the animation all four sides start moving. I just want it to ‘build’ up from the bottom to the top just like a construction 3D printer works. What can I do?
Hmm, very hard to diagnose the issue without knowing more about how you're creating the cube design. Is it a mesh cube? Or some kind of design you've imported? The reason the printing effect works in the tutorial is because the print track is one continuous curve. This allows it to unambiguously assign spline parameters of 0 at one end, and 1 at the other; toggling between these two values uniquely maps a position along the curve. If your design is discontinuous, or has been created in a way such that points are not connected in a smooth continuous way (i.e. two points along your path with spline parameters "n" and "n+1" are actually right next to each other), you will get weird effects.
@@ryomizutagraphics it’s actually a cube, but I figured something out. I will convert it to a curve and then in edit mode delete all the other parts until I have one single part left and then duplicate it until it forms a cube. Let me check how that turns out. I’m also not using a nozzle, just the movement of the 3D printing. The only thing I need to do in order for my technique to work is to use keyframes for each part.

For anyone having the same issue as me where you have wierd cuts on the corner you need to add more subdivisons at 1:10

Excellent!

Ingenious!

Interesting !
