Introduction<\/h2>\n\n\n\n

This is my first time using the CLAY printer, and the experience has been truly fantastic and amazing, despite the many challenges I encountered while preparing the material and printing. First and foremost, I would like to express my gratitude to the Hand and Machine Lab for sponsoring the Eazao printer. Special thanks to Prof. Leah and Fiona for helping me get familiar with the machine.<\/p>\n\n\n\n

Process<\/h2>\n\n\n\n

I was excited about the example given from the Turtle Library, but its shape seems too complex to print by the clay printer. I failed to print some the example works. Then I turn to some simple shape, like simple geometric shapes that were created by superimposing two polygons.<\/p>\n\n\n\n

My overall design idea is to use two for<\/code> loops: the first for<\/code> loop is used to print the layers, and the second for<\/code> loop is used to print the different edges within a specific layer. I experimented with both simple and complex functions to achieve this.<\/p>\n\n\n\n

2.Mini-WaveCrown<\/p>\n\n\n\n

3.LoopContainer(a cube with 3 ears on each side)<\/p>\n\n\n\n

Based on the previous work, LoopContainer<\/code> will, on the specified layers in the if<\/code> condition, draw a simple equilateral triangle midway while printing the edges, and then return to the original printing path.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

First Version <\/p>\n\n\n\n

If the clay is too soft during printing, the printed clay will squeeze outward, causing the actual height to decrease, resulting in a large gap between the nozzle and the current layer when printing the next layer of height, resulting in the result shown in the figure. The printed shape is granular, not smooth.<\/p>\n\n\n\n

Second Version<\/p>\n\n\n\n

Challenges<\/h2>\n\n\n\n

Unexpected Outcomes<\/p>\n\n\n\n

When I was printing, I found some shortcomings of clay printing. For example, if the height of the second layer is too low, the nozzle will be very close to the first layer, which will destroy the original structure of the first layer of clay, allowing some clay to escape outward or inward, causing it to be not smooth.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The first challenge I met is that the extruded clay are so soft and discontinuous when it float wtihout support, it looks like the second picture. The method I try to improve is to modify, adjust the extruder speed and moving speed.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

This is the second challenge I met, on the right of this printed work, the second layer wasn’t corrected printed on the first layer, so there will be a 0.3mm gap in z axis. That’s why you see part of the print result as granular.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Sometime, the fried clay is more fragile than PLA printing work, so you should take care when you remove and touch it. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Drying and Frying<\/p>\n\n\n\n

When we finish the printing, the drying and frying is most important, which could make the printed work harder.<\/p>\n\n\n\n

Reflection<\/h2>\n\n\n\n

First and formost, it is really easy and comfortable to use Turtle-library to design the work you want print, because it is more flexible, especially, I think the t.foward_lift() function do a good job, you could produce object with contour variations along the Z-axis. The traditional silicing software it seems can’t do this job, they could only print every horizontal layer step and step.<\/p>\n\n\n\n
