Making Things and Stuff: Idea 1

I would like to make a funky layered ring, using some of the seams and ways the printer will print to make patterns and texture. 

Some stuff from class: 



Set up for the ring: 

Making various circles for a smooth inside and funky shapes for the layered outside. 


Layering them circle, funky, circle, funky; going up by the size of the layer size of the printer. 

The finished rat's nest. 




Set up: 

Used the homemade definition from class to try and see a model of it. Only, this happened. So, I had to make a box around the rat nest to then be able to cut it and do all that other stuff. 

Which only cut the normal circles and not the squiggly lines, but good enough. 


Then I used the provided gcode to set up the file for in-class printing. 


And here is the set up for streaming the gcode. 


Other Things and More Stuff: Idea 2

Talking with my group for the final project, we decided that part of it would be us printing on fabric (on top of the drawing we do), so I decided to adjust my ring a bit to test the limits of trying to 3D print onto fabric. 




Le Print

(Obviously, you were there helping me print, but here are some things I observed from my end, as well as some of the final results.)

First, the file was somehow in the wrong size (I honestly don't know how that happened. Maybe I was in cm instead of mm?)
But that gave me (us) a good idea on how the layering behaves and if it even worked. 

Then we shrunk it. But there was some additional shrinkage that we didn't account for. 
With a bit of sanding, it might actually fit my pinky finger. 

Then we adjusted it to make it the proper size, which was too big for me. But fit well enough. 

Then we shrank it again (and it fits a lot better) and then you also adjusted the seams for the print so that it didn't have the lines through the middle like the other versions. 

I also sanded down the smallest one and it actually fits my pinky finger now. 



Here they are together: 

A fun collection that honestly worked a lot better than I thought it would. 
Even the fake renders didn't come close to what it ended up becoming. It layered up nicely, and I probably could have gotten rid of the outer structure ring, but that did make for some cool squishing and printing as the filament went over itself. 


After a break: 
Printing on Fabric. 

Both types of filament seemed to bond quite well to the fabric, it even went into the grooves and fibres in some places. 

All in all, good experiments. 
Thank you.

Making Him into a Poster GCode stuff  Resizing the boy once again to see what size I want.  Made him a bit smaller than the piece of paper I aim to use so that I can have some buffer/wiggle room.  Fix the sort curves Fix the draw bed Edited some values Changed around the colours Checking the code (NC Viewer).  Printing/Drawing  Okay, so this was a bit of a process since I'm fairly sure I was the first to draw after class (I did it before the break, and just before Peter sent an email saying there would be no support).  But I figured it all out myself and Geoffrey is glorious.  So, right off the bat...there were two major problems, the machine wouldn't move no matter what I tried and I couldn't see where to override the axis to move it around properly.  I looked it up and...I needed to move the motors away from the sensors because they were too close and the button to override the motors was under a different tab.  But, once everything was set...

Making Geoffrey into a Poster Step One: Get Geoffrey Step Two: Go buck wild with "Make 2D" Fun angles (what I like to call 'dog asking for/smelling food')   More full body Hats and Rage Existential crisis Okay, two drawing options.  Decided to go with the Jaws-like poster.  First, I separated out the one section I wanted to be filled (after cleaning up the lines, as there are always some double lines or just weird ones that are unnecessary).  I wanted to do an offset fill, but the file on Google Drive wasn't working, so I looked up some stuff and also somewhat brute-forced it.  Eventually, I got this.  After, I changed up the text so that I could do another fill there. I did the concentric fill, though, it did turn out a little janky and has these skips in them. I like them, so I left them.  Here is the finished boy! And the setup for the different colours of the poster.  (They aren't filled in because I still need to do some scaling once I figure...

EXPERIMENTAL DIGITAL FABRICATION (Final Project).

The Collaborative Sweater Team 2: Me, Cain, Aryan, and Sim We talked in a group about ideas and came up with using the CNC machine to draw on some fabric and then 3D print some sections of the drawing to highlight them, which will be turned into a sweater.  Thanks to Cain for organizing all our ideas to streamline what we are doing.  ( Notes Here ) The Patterns:  The sweater pattern (black lines) was split into sections for each of us to fill out.  Here is mine:  The Drawing:  Okay, so...a lot happened during the drawing of the CNC machine.  First, the setup was pretty easy. Aryan had set up the canvas by stapling it to a board that we could clamp down to the bed of the CNC machine. Doing a small test, the sharpies drew quite nicely and easily with minimal drag (though there was still some drag...as you will see).  Though we did have to centre the machine in the middle of the fabric (because that's the way that Aryan set up the file, which is actu...
