A few updates for this week! I successfully printed the first half of the project. The print took roughly 14 hours and required no supports other than a brim. Because of this, the print turned out to already smooth and needed no further sanding or prep. This made my life so much easier, and the job much easier for the printer as well. I think that this is incredibly uncanny, and especially because it is to scale it is very strange.  Images of finished product #1: I also feel that the4 hardware on the print will also work well with hanging materials such as hooks and nails. Despite this however, there are still several setbacks, initally I scheduled my print for thursday, but I ended up going over my bookings time and so, I needed to cancel. That brought be to saturday, which was the next time I had prepared for the printing of the arm. However, the lab RAN OUT of fillament! I didn't expect this to happen but unfortunately, production will have to be moved to this following week. Th...

  This weeks updates This week has been hectic. I fell behind for a moment there and I even considered abandoning my project completely. There were several times that I sliced my objects on Prusa and realized I had nearly 30 hours of printing ahead of me. This was daunting, yet, it did appear that the face would be no issue on the printer so long as no other students interfered or any other inconceivable thing could happen. I decided to fire up the prints and walk away, for my sanity.  I also had a considerable amount of modelling ahead of me, with the issue of my scans having several holes in them. At first, I considered using a powerful system such as blender to remedy the designs and doing my best to follow tutorials online for the clay tools, but, after a lot of struggle I ultimately chose to return to mesh mixer, even if it was a lesser version after a THREE year hiatus.  The process absolutely had its growing pains. Time after time I experimented with each brush to ...

  Project Two Updates After completing the first scan I can now confidently say that the face scan went off without a hitch1 YAY! the process was much quicker that I had initially expected and I will be able to send it off to the slicer and edit my setting to get the ideal print. As it stands the time will take is likely around 16 hours of printing, which for using a model of this size is not terrible on the Prusa XL. Overall, it is smooth sailing for now, with very little setbacks. Although the scan had gone beautifully for the face, there always has to be something. I am somewhat upset because the scan for the arm did not work out as intended, there are some problem areas unfortunately and the mesh should likely be touched up. Ideally, this could be something in blender that I can use the clay tools for, but my knowledge of the system is incredibly limited. I will make sure to chat with Bryan about this and see if I can enlist some help here to learn how to do this. At worst, the...

 I propose to create a second bespoke item, this time however I would like to learn how to use 3D scanners to CAD. I have always wanted to utilize this skill to create a highly intricate object which could become piece of fine art. I hope to create something sculptural but still obviously true to the medium of 3D printing, I do not plan to paint or sand the object. I also could be open to showcasing it as part of the graduate show this may when I convocate!  My idea is foster the current research I have been doing in my drawing art practice which is about the intersections between ecology and feminism. specifically Eco-Feminism. Because of this, I would like to create 3D scans of my body, which is similar to how I also take imprints of my body in organic materials onto rag paper, and splice the scans into segments of limbs which can be hung flat on the wall. I would like to use perhaps a resin printer for this process or the new larger Prusa printer. I also plan to design spot...
