This is another sculpture (the "Christ Unlimited") from the artist Herman Makkink that also appear in "A clockwork orange" movie by Stanley Kubrick.
In the movie it can be seen briefly in Alex Debarge's bedroom.
I made this 3D model a long time ago from the photos I could find, but never printed it because I think it's not good enough.
I'm not happy with the proportions and posing of my model and if I was to do it again I would probably do it better.
But this post is not about the modeling process and quality of my result, and more focused on how a good strategy can save a lot of print time.

A few words about the modeling process...
As I told you I did it a very long time ago.
All the proportions and posing session was done in Quidam, an old 3D posing app by the french company Nsided.


The program let you pose a human figure and then export it as OBJ.
From there, it was further sculpted in SculptGL to add details and make it look more like the original sculpture.
I remember that the complete modeling session took me about 5 hours from scratch, but as I said I'm not happy with the result.


Anyway I recently found it back on my hard drive and decided to print it 30cm high (while the original seems to be 52cm).
So I opened it in Cura and tested how long it would take to print it in one go.
Cura calculated a 12h10mn print time with quite a lot of support. In fact the support by itself is about 6h40mn while only 5h28mn is spent on the sculpture.
This is more print time spent at support printing than on the object !
And I want to print 4 "Christ Unlimited" to match Alex's bedroom look and feel.
So I decided to find another strategy...

To reduce on print time I made several cuts at well chosen places.

Christ cutted

The first cut is made on a plane going from the left elbow to the bottom of the face (at the tip of the beard).
A second cut is made at the bottom of the stomach before the legs separate.
And the legs are both cutted in such a way that each of them is just high enough to be used to support both hands where a lot of supports will be needed.
So to resume, the sculpture is cut into 5 parts but will be produced in just 3 separate prints :

  • head and arms + calves (3h32mn print)
  • torso (1h41mn print)
  • thighs (1h51mn print)

Which makes a total print time of about 7 hours.
Compared with the 12h10 mn print if I had printed it in one go, this is more than 5 hours saved on print for each sculpture. More than 20h saved for the 4 of them !
And also a lot of material saving because I'm producing the calves instead of producing wasted supports.

Print finished

You can also see that I placed several 3mm diameter holes here and there to help for the assembly and gluing process.
And I will use 3mm diameter raw filament as keys
A soon as one complete "Christ Unlimited" is printed, I can start gluing back the different parts while another one prints.
One very good point is that my model is well balanced and can stand on its feet by itself like I had planned.

Once all four will be assembled, I will have to :
- sand them
- paint them
- cover them with epoxy resin
Still a lot of work !

Here is how it will look like when done (textured 3D version) :

That's it !
I hope it will help you in planning a good print strategy for your future BIG projects.
