Zero Vinyl Toy Final Progress

Zero-made-of-Glass

Before continuing to model the body, I had fun trying out Keyshot!

In order to model Zero’s body, I used the photographs and one scan to create reference lines, and tried many different commands such as Loft, Sweep2, Rebuild command, and NetworkSrf to connect the lines into a surface. NetworkSrf produced the best results, but needed more reference lines than I had expected.

Connecting the various parts presented a bit of a challenge: the mouth in particular had too many disconnected edges, and I ended up having to revisit it and come up with other solutions. Once the entire toy was assembled (ears, head, mouth, nose, body), I began creating renderings in Keyshot. After playing around with different materials, I went back to the Rhino model to separate the model into layers according to colours. I then brought it back to Keyshot and used the plastic materials as colouring, as well as adding a backdrop image found at http://f.fwallpapers.com/images/nightmare-christmas.png.

The next part was the actual 3D printing: I quickly discovered there were a few more steps before bringing my Rhino model into Tinkerine, such as getting rid of naked edges, creating meshes, and exporting each piece into an stl file. I decided to print the body, head, and ears separately in an attempt to use less support material to speed up the process, and also to allow the head to be able to turn. A problem that came up while printing was that the PLA material did not stick to the base surface very well, so the bottom surfaces ended up with gaps where the material was pulled away by the printer head. Overall, the 3D print result worked, although with less detailed precision than I had prepared for.

To finish up the project, I used the Make2D command in Rhino to generate line drawings of the figure from different views. To improve the drawings, I then added and deleted specific lines.

zero vinyl toy head

After Kara scanned our cuts of the toy, we brought them into Rhino (with the PictureFrame command) to trace for further accuracy. I had traced the head from photographs and used RailRevolve to form the basic shape of the head. I also used RailRevolve for the pumpkin nose. I formed the eyes by making ellipse shapes, measuring where they were supposed to be on the head, and using BooleanDifference.

One of the most difficult parts to figure out so far have been the ears. I began by tracing a Top View of the ears with a ControlPointCurve, then moving into Right View to manipulate the straight curve into an undulating shape. The most successful smooth edged ear so far ended up coming from the Sweep2 command.

Zero’s mouth is even more of a challenge : some failed attempts used the commands RailRevolve, EdgeSrf, Extrude along Crv… The mouth that worked the best was made using a lot of curves traced from the photographs and scans and the Sweep2 command. There is still an unwanted ridge in the middle, but is the most successful attempt so far.

My next steps will be to refine the head, and work on the body.

‘zero’ vinyl toy cut

After using PictureFrame to place scaled images of the toy into Rhino, I modelled the basic head shape and used FilletEdge to smooth it out. To try and model it more accurately, I traced some lines as frames to be able to use the Rail command to generate the shape later (the red lines on the left).

Tonight, my partner and I were able to cut our cast toy into 3 pieces. We were careful to measure where to cut vertically along the middle, and also horizontally through one eye. The acrylic box around the resin was able to peel off and I really like the way the resin pieces turned out. They will be a good guide for measurement of the length of the mouth, the width of the neck, and the width of the base. The next step is to take images of the cuts into Rhino for further reference material.

My partner and I cast our toy in resin in a container we made of acrylic. This involved ensuring the container was watertight, then pouring the resin in layers and letting each layer dry for 20-40 mins. We have not yet sliced the block, but took pictures of the toy for consistent front, sides, top, and bottom views in order to begin modelling. We then scaled these images to be the correct size.

After bringing the scaled image into Rhino, I made some rough frames of the general shapes based on the images’ dimensions. For the frame of the body, I drew two circles based on the collar and base dimensions, then separated them based on the height measured from the images. I then used the loft command to make the cone shape.
