MAKERBOT REPLICATOR™ 3D PRINT RESULT & ANALYSIS P H O T O S
Fig.1 Overall Result Overall results of the print was largely satisfying, as the physical result was very similar to that in the Makerbot preview. The details are quite successful considering the 0.3mm print resolution as opposed to the expected 0.2mm.
Fig.2 Scaffolding The makerbot preview had minimal scaffolding structures and so did the print. However, visible artefacts are present in the lower quarter of the head sphere, this may have been due to printer glitching or one-off software/ hardware issues.
Fig.3 Raft The raft was nicely printed and was relatively easy to remove. Small scaffolds were visible bridging between the raft and the bottom of the print under the belly and feet.
Fig.4 Lower Body Details Scaffold visible connecting body and head; small wings at the back not obvious, may need to upscale the structure; successful print of feet and arm details; talons top slope may need to be reduced to a 0 degree incline to minimise visible print strand artefacts;
Fig.5 Face Details Great definition in the brow/eye socket/eye-bag regions, details of dimples also visible.
Fig.6 Forehead Details Layers of print is visible, not a huge issue; Details of dumps and subtle displacements are nicely visible; Inner ears may be too thin, small loose strands artefacts visible at thinner regions;
Fig.7 Wings Upscale The wings at the back were scaled up to increase legibility.
Fig.8 Lower Talon Incline Angle Hopefully by lowering the incline of talons a the back, artefacts would lessen on the top ridge of these talons.
REVISION OF ELEMENTS S c r e e n - s h o t s
Fig.9 Inner Ears Upscale Inner ears up-scaled by a factor of 1.3, thin members facing away from centre also allowed to lean/intersect with thicker geometries of the outer ear for support to increase the likelihood of a successful print.
Fig.10 Outer Ears Upscale Outer Ears were upscaled by a factor of 1.1 to slightly increase printability, as the last physical print results showed that the thickness of the outer ears were pushing the limit of an unsuccessful print result.
Fig.11 _What Check Ensuring the final booleaned polysurface is watertight and a closed volume.
Fig.12 Naked Edges Check Pass. Proceed to Makerbot preview.

Fig.13 KORI v7 & KORI v8 When placed side by side in Makerbot, the subtle changes made can be noticed (version 7 on the left, version 8 on the right).
Fig.13 DMAF Settings Preview was done this time in accordance to the USYD DMAF lab setting for the Replicator 2, to get a more accurate representation of the result if the print is to be completed there. The major difference of this to the previous previews is the layer height, or the print resolution of 0.3mm as opposed to 0.2mm setting used previously.

*Tubing is assembled by gluing separate card cutouts, PVC then glued on the inside of the card
Packaging Parts 1. Paper carton (2.8mm cardboard lid) with ‘sky light’ (0.23mm clear PVC) 2. the ‘Space Karrot’ (leaf), 1.4mm frosted polypropylene (painted green afterwards) attached to the packaging underneath by hot glue. 3. the Space Karrot(body), 1.4mm frosted polypropylene (painted orange afterwards), relatively strong to hold toy inside, translucent to give a hint of inside content while keeping a sense of mystery 4. Support pot for the Karrot, 0.3mm paper, 2.8mm card base 5. 2.8mm card, 0.23mm PVC window to frame product inside, PVC glued. 6. Single piece net of the Karrot, no glue necessary 7. How each part sits inside another. space allocated to some movement allowed to absorb shock during transit, the pit at the top of the Karrot as well as the extrusion in lid keeps the inside content upright

Instructions Once Kori is taken out of the Karrot, the Karrot can be reassembled and placed back into its pot.

RENDER PROCESS S c r e e n - s h o t s
Fig.18 & 19 Studio Canvas Setup A curve was drawn then extruded to form backdrop for studio lighting setup
Fig.20&21 Key Light Setup A rectangular light using Vray was placed above the packaged product and angled down at around 40 degrees to provide a key light.
To Avoid blocking the camera, the light was set to invisible, so the camera behind would be able to see the product without interference.
Fig.22&23 Materials Necessary Materials were applied to the product. Degrees of reflectivity and specular is changed via the glossiness setting. Subtle bump maps were also experimented with to add details. Since Kori is supposed to be an Alien, the materials used is quite metallic and shiny to fit the sci-fi theme. The packaging texture is not overly complicated to compliment the complex detail of the doll inside.
Transparent materials were added with refraction index of 1.2. Overall GI settings were changed. Secondary bounces algorithm was changed to ‘Light Cache’ from ‘Brute Force’ to give better results for this particular scene in the shadows. Ambient Occlusion was turned on and the radius was lowered to 5.
Fig.24&25 Side/Rim Light Setup Two more rectangular lights were setup on either side of the scene, one set to a warmer tone, the other one a colder tone to create subtle colour contrast.
The contents of the packaging is removed to show various stages of opening the contents. Also to create better composition using packaging as background.
RENDER PROCESS CONT. S c r e e n - s h o t s
Fig.26 &27 Composition The focal length of the camera was changed from 100mm to 40mm, to give more dramatic look, also to give more depth to the shot. The subject is moved to occupy the right third of the frame
Fig.28 Readjusting materials The window of the tube does not have enough presence, the dark surfaces inside the container shows through and distracts the eye from the toy.
Fig.29 Re-texturing belly and Ears Small adjustment to the bone structure of the ears and the belly to differentiate some body parts so the toy does not look too homogeneous.
RE-TEST IN MAKERBOT PREVIEW S c r e e n - s h o t s
Fig.24, 25, 26,27 Small Adjustments Side lights were set to invisible.
Camera angle tilted up and away to give better framing. Depth of Field enabled to draw attention to subject. It also brings in more depth to the render.
FINE DETAILS ADD-ON S c r e e n - s h o t s
Fig. 28,29,30 Post Production in Photoshop After the full size render is exported, it was edited in Photoshop to create mood and atmosphere.
Some processes used were: 1. colour correction 2. colour balance (magenta to the shadows, red and yellow to mid-tones, cyan and green to highlights) 3. Foreground texture/obstruction of snow, Gaussian blurred. 4. ground plane textured to a snow field 5. Vignette 6. Re-cropping to add final touches to composition
Logo text added to finish off render.
