Print orientation /articulated joints

Recommended Posts

Posted · Print orientation /articulated joints

It seems that I just keep creating models that are difficult to print.  For me anyway...

So I am working on a scorpion.  Biggest issue is the arching tail and the legs.  I did one where I supported the legs with a rocky base.  That works for the legs, but than I need to do the tail as a little add on.  I split the whole thing saggitally and got the tail and body great, but the legs break off.

But then, I started trying to set it up so that a few of the joints will move or articulate to some degree since I felt like I had to cut off the legs and claws anyway.  All of the sculpting is done in Zbrush, and I am working on trying to best create pins or ball and sockets for joints.  

Now that it is cut into pieces there are some sections that I just can't seem to decide how to best orient after splitting off. Now the parts have to be supported and have no solid base and keep failing.

The legs in particular are a real bear.  Maybe I should print them straight and then heat and bend them?

I have printed it a couple of times in different ways, but still not satisfied.  

Here is where I am so far.zbrushscorpion2s.jpg.d532c6a5046dbbc8d4d14084f20c3661.jpg

Here is one of the prints, I had to glue several pieces back on. This one was the one printed half and half down the middle. I find that to work great on most things that are somewhat symmetrical as it allows for a real sturdy flat bottom to begin the build.

How did the joints turn out?

@Valcrow has a lot of expertise in this area, maybe he has some good tips?

Too loose on my first attempt, I had to glue them in. Working on a new attempt now.
