Hello,

My name is Ion Grozea and i intend to build a panoramic head mechanism for my DSLR camera using 3D printed parts.

My project presentation can be considered also a small tutorial based on my experience related to large parts printing.

Based on the experience i have so far with the Mooz 2 3D printer (got it in January) i have to say that i have a lot of headaches related to the printer bed (i have 1,5mm difference between calibration points due to loose screws and waves on the bed surface at 100C because i use ABS - I HOPE I WILL GET A REPLACEMENT PART) and due to the surface finish of the parts.

Now, for my project i have to print several enclosures for electronic boards and also the enclosures for the gears that i use for the movement.

As seen in the image above this is the part quality i get from the printer, this is not acceptable for my project. I have used the acetone vapors method to smooth the parts but i end up throwing away all of them.

Now i apply acrylic paint as a filler in several layers, between each layer i leave the paint to dry for 24h and then i put the part in oven for force dry and stress release at 80C for 1h.  The images above are showing the parts during the acrylic painting steps.

At this point i am using as final step 2 layers of Snow flakes paint that gives the surface a orange skin look.  For the head parts i am using the same method, but here i start with the thermal treatment right after printing (2h at 90C) because for these parts i need a better fit.

The images above are showing different steps in the assembly of the panoramic head, last image is showing the enclosure for the gear with the servo attached. Because of the 3D printed parts tolerances i have to make a lot of adjustments.
