4. Parametric Furniture Scale Model (Physical) (iii)


This is my physical print, it was done with clear acrylic laser-cut pieces glued together with crazy glue.
(At the end there's a 3D print version!)





So I laid out 32 pieces to laser cut which I thought was enough, but it surprisingly still too thin compared to my rendered file. Which is fine because the table is suppose to be adjustable for width, angle height, and amount of curves/grooves/waves. And glueing it together wasn't perfect either because some pieces wanted to shift right before the glue dried so it created a wavy shape in every other angle too... yay...

And some of the pieces were cut on a non-flat surface of the acrylic, which is weird I didn't know that could have been an issue until now. I glued together pieces 2 by 2 then join those to 4 by 4, then 8 by 8. At this point is where I found the issue, where there were random gaps in between the laser-cut pieces (see pictures below) and no matter how much I try to sand the edges, it would not go together. Thats how slanted those random pieces were... 

Then I thought I'd try to use epoxy resin to fill the gaps... Ha ha... big mistake. For some reason it had a chemical reaction or something so the acrylic pieces that were touching the epoxy tinted yellow... Not just the surface because I tried sanding off the first coat, it actually tinted the INTERIOR!!! So I had to break apart my lap desk that was basically done, and re glue them together. So I'm not fully happy with the way this end result looks as of right now, it is cool that it's a clear table and all but the glue residue, sanded bits, uneven pieces laid together... It's not what I would have wanted my project to look like so if I have time this week I'm going in to 3D print a version that's more accurate to what my render looked like. Just in case my "at a scale" model is suppose to look exactly like my parametric render, because it doesn't right now and I want it to look better than the laser-cut piece. I'll bring in both on Friday but ahhhh frustrations, we'll see what happens. I kind of wished I didn't glue them together to be honest, not sure how that would have stayed in place but they looked perfect before I glued them together... Enjoy my process of making and peeling the acrylic down below!

SURPRISE! I thought about it and I couldn't get past myself. I went to 3D print it literally after my initial post (on friday) because I felt like I could have done better. So I did better. Of course not without struggles though... 



3D printing something as tall as my table, I already knew I couldn't just print it as tall as it is right now. So I sliced it in half and printed them separated on two printers at the same time. Somehow my trusty old tango that I always print with failed me twice before the final one printed right and it was the only one with a skirt. 







All 4 prints came out with a weird section about 10 layers in where it shifts or "melts" and thats where the lifting began. Which surprised me that even the last print I made with a skirt, it still lifted up a bit. You can see it in the side by sides of the two big pieces together. Really strange, not sure fully how I'd fix it but that was a strange situation I couldn't fix. The left smaller piece in the 2 halves side by side pictures, that print fell over 6 minutes before finishing, like right when I was about to do the whole New Years count down in excitement that it would work, the whole thing tipped over and burnt a small spot on the curved turn... Anyways, here's some final render photos. Enjoy little Carmen being used as a prop along with a mechanical pencil and an old cinema ticket.

4. Parametric Structure Scale Model (Digital) (ii)

Title: Lap Wave Desk Inspiration: Ocean/Wave glass sculptures and The Great Wave off Kanagawa print by Hokusai Difference from typical furniture: A typical lap desk is formal looking, just metal and a plain one colour platform. I wanted something that's less traditional and more sculpture base, one that looks like an art piece and might benefit some users with the wave patterns as holders.  Function: It's a lap desk! Those computer desks are portable and you can put them on your lap to hold your laptop on. Others might use it as a standing desk by putting it on top of a regular table Intended Location: Homes and maybe a less traditional office Intended Audience: Students, office workers, people who need to do work standing or work portable Here are the renders for my lap desk, I made two versions of it. One in an Oak material, one in transparent plastic with a slight blue colour just to make sure it would appear in the render. I made the decision of the transparent one bec...

Papercraft Research

What is papercraft?      Papercraft, to my understanding, is a paper-made art and craft. Paper is the easy-to-find medium so it is easy for people to use paper to make things with, in our case we would be making 3d objects and understanding how folds, crease, and tabs should be connected in order to hold pieces of paper in place. Reviewing an article: Popupology      The Popupology shop papercraft caught my eyes first. On the Colossal article, scrolling through that article, everything seemed very busy and complex, which I totally love, but it's not really my style. The Popupology shop ones, on the other hand, seemed so simple but so cool that it caught my eyes. Especially the hand-cut out one, how that is just a simple cut-out flipped on the other side and having it pop out with the thumbs looking like it's intersecting, that really stood out to me. Because this reminded me of elementary and how we used to do these DIY pop-up cards for holidays, t...

Memorial Jewellery Documentation II

Here's part two of my memorial jewellery piece, the final renders and explanations for my decisions on this project.  The functionality of the ear cuff is still iffy to me. I tried to create a hinge for the bottom curve so that it would make sense as a piece that uses the earring hole, instead of just being a metal that hangs on the ear. But overall I feel like it is still lacking in that portion of the design because it doesn't fully make sense. I would assume that you'd have to wear the bottom part through the earring hole before clipping the back end together and hooking it over the top of the ear. And because I created it as a hinge-based opening, I had to pair it with a snap post closure instead of the screw back I had initially chosen.  Theoretically, this ear cuff curvature would have to be adjusted from person to person because it's more personalized to fit an individual's ear shape. Plus it's designed to be aligned to the outer earlobe piercing so it wo...
