Description
In my continuing quest to learn new tools and techniques, I set out to learn OnShape and create something perhaps a little different than my usual fare.
I've always wanted to create a "Twist Vase" of sorts so I set out to do this in OnShape.
After some experiments, this is the result I came up with. Its two opposing twists which led to something that reminded me of intertwining sinew. Asymmetry on one plane and symmetry on another leads to an effect that triggers a feeling somewhere between chaos and order.
Itis possible for this to hold water, though you may need a bigger nozzle in combination with shorter layer heights.
For an example of the vase holding water, see this silly video: https://youtu.be/WcyIUXXModY
Printer: Bobs CNC RP9 v2
Rafts: Doesn't Matter
Supports: No
Resolution: 0.4mm
Infill: None
Notes:
To maximize the chance that the vessel will hold liquid, I encourage you to use a larger nozzle diameter (I used 0.8mm) and a shorter layer height (0.2mm-0.4mm). In doing so, you will ensure layers will overlap more as the printer prints the spiral.
Higher temperatures for PLA along with slower speeds and good cooling will also maximize layer adhesion while preserving surface finish. I actually pushed the temperature up to 240C and kept the speed around 30mm/s. Part cooling fans were off for the base layers then on at 40% after the base layers. Each printer is unique so you may need to adjust parameters on yours to get the best result.
Also, this particular vase is made up of two bodies. I have had no issues slicing in Cura, although it is possible that the model may need to be repaired for some slicers to work with it. I will likely be checking it out with Meshmixer soon and upload a repaired model if necessary.
If I get around to making a tutorial, I will place a link to it here. Take my methods with a grain of salt - they are not necessarily the best.
