# Laser-Cut ArcSin Dress Is Wearable Math

Using sewing simulation, 3D modeling and laser-cutting [Nancy Yi Liang] makes custom dresses that fit like a glove. Her project documentation walks us through all the steps from the first sketch to the final garment.

After sketching the design on paper, the design process moves into the digital domain, where an accurate 3D model of the wearer is required. [Nancy] created hers with Make Human, a free software that creates to-size avatars of humans from tape-measured parameters. Using the professional garment modeling software MarvelousDesigner (which offers a 30 day trial version), she then created the actual layout. The software allows her to design the cutting patterns, and then also drapes the fabric around the human model in a 3D garment simulation to check the fit. The result are the cutting patterns and a 3D model of the garment.

Through creative use of the online graph calculator Desmos, [Nancy] put together a mathematical design-pattern from inverse sinus functions, which she later mapped onto the previously exported 3D garment model in Blender. With everything aligned nicely, the cutting patterns could be prepared for laser-cutting in Inkscape. She got the shapes laser-cut from black and white fabric in her local makerspace, and after sewing the pieces together, [Nancy] could try on her creation. It’s great to see digital manufacturing techniques being used creatively in garment manufacturing. Check out the video below, where she presents her ArcSin dress!

Thanks to [Simon] for the tip!

wow, what a beauty!
good job!

If only I could buy work clothes like that.
Better still do a 360 deg body scan send away the file pacify the material and back comes perfectly fitting clothes

Check out MTailor. They claim to be able to do just that. I haven’t purchased anything from them yet, but it seems promising.

Hi, I’m the designer of the dress. There’s quite a few bespoke men’s shirt companies, not so many for women. Designing for women is harder and the styles are more varied, so I understand why.

There is a researcher at NASA (sorry I can’t remember her name at the moment) who actually did do all the maths for close fitting space suits to ensure they were not going to restrict moment.

1. Dan#8582394734 says:

movement… doh!

2. Rodney McKay says:

If it could restrict moment, that could really cut down on the need for thrusters.

1. Dan#8582394734 says:

Yes, but it wouldn’t help typo detection.

1. Rodney McKay says:

Typo? Is that a previously-unknown type of cosmic ray?

3. Nancy L says:

Oh that’s cool! Yeah, there are a few areas where I imagine being able to make bespoke garments would be life and death. Dry suits for divers is another area.

4. There’s a pun about arcsin tan lines in there, but I’m not smart enough to make it

5. A beautiful example of form following function. Literally!

6. Jonathan Wilson says:

Very cool, wish I had cool clothes like this (not a dress obviously but a shirt of some sort would be neat…)

1. Nancy L says:

Thanks! I think my next project might be a shirt. Still made for women though. You can make your own! I just started sewing not so long ago, and most of the software I used are free.

7. echodelta says:

Fit like a glove, huh? Didn’t it just get discussed here lately, about spun clothing.
Hang, it’s a woman’s garment, not underwear. Seems that there is an additional layer of modeling to get the flow and grace of good design, not stiff ‘3D’ graphics. Go for it.

8. Rodney McKay says:

To hell with laser tailoring clothing to fit me. I want to laser tailor myself to fit the clothes of my choice.

1. Moritz Walter says:

Sit still, we can do that from here.

9. JIm B says:

Very nice! I wonder if there is any significance to the blue and gold color scheme.

1. notarealemail says:

Thanks for that. :)

10. Robot says:

This is great. Conceptually concise and well executed.

11. john pak says:

Now this is the kind of fashion I can get into.
