I’m completely new to 3D Printing, but so far have been having fun. I think I’m doing something stupid here, but could use a quick sanity check. I cannot add two objects together for the life of me. I watched a bunch of videos about assembly, but the problem is the objects won’t stack at all.
Below is an image of the two. All I’m trying to do is give this coast some height without having to print all the detail over and over for 2-3mm. So the full blue would be the bottom and the rest is the top.
How did I do this? (Give a man a fish, and he will have print today, teach a man to fish, and he will print every day.)
Notes:
Your design element was 0.5mm thick, which would only print two layers, as your layer height of 0.2mm means it will only print the first 0.4mm.
It is far more common to have a 1mm thick design portion, or the colours behind the design will seep through, the blue would show through the white.
I wasn’t sure if you wanted a common 2mm or a thicker 3mm version, as you said 2-3mm.
Most coasters are 100 mm in diameter; yours is smaller. You can stretch it using the scale toolbar feature if you wish.
How to reproduce:
I noted down which colours were assigned to which objects in the design portion.
I selected your design portion as one item and used the scale toolbar option. I turned off “uniform scale” and set the height to 1mm.
I selected the design portion and right-clicked, and selected centre, it already was, but just in case, always do this.
I selected the disc portion and used the scale toolbar option. I turned off “uniform scale” and set the height to 2mm (optionally 3mm).
I selected the disc portion and right-clicked, and selected centre.
I select the whole area using the shift key and dragging a selection area around both parts. I find that easier, but you can use the object panel if you prefer.
Right-click and select Merge from the context menu.
Using the objects panel, I made sure the cylinder object (the disc portion) was the highest item in the list of child objects of the merge. It was sometimes when I played around, other times it wasn’t. As it is the background, it MUST be the top entry.
I reviewed the other objects to see if the original colours persisted, and sometimes they did, sometimes they didn’t. I selected the incorrect entries and chose the correct colour.
I now had a perfect 2 mm-thick coaster facing down; this would generate a coaster with the buildplate texture. This is my preferred method.
As some prefer it facing up, I did the following.
I added a build plate and selected it.
I right-clicked the face down coaster and chose "clone’ from the context menu.
I left the copy count as 1 and agreed.
It created the duplicate on the second build plate.
I right-clicked the new coaster and selected “Mirror > Z”.
I right-clicked the new coaster and selected “Mirror > X”.
I now had a duplicate that would print face up with the design oriented the right way. Less important for this design, but worth remembering for when it matters, mirror both Z and X.
OK, I’ve tried to follow along (because this is really similar to a problem I’m having) but I can’t get it to work. First problem is that I can’t figure out how to change the order of items in the object list. I’ve got two things, one is always on top.
Second thing is that I can’t get one object on top of the other. No matter how I move the thing I want on top, It always snaps back to the print bed.
