dating back to the 1890s, it's the work of a German seamstress who had been consigned to an asylum. Although it's often falsely described as her straitjacket, it was actually cut and assembled from a hospital gown, tailored and then turned into an autobiography wrought on fabric.

## What is craft?

- 1000s of years old
- Highly skilled
- Only labeled “arts and crafts” after the industrial revolution
- Often centered in women’s “busy” work
- Sometimes entrepreneurial 
- Exceptional at addressing unique and individual needs

## Modern crafting technology
- New ways to ideate and create: Faster, easier, sometimes better
- New ways to customize: Faster; Mass customization
- New materials
- New and/or more complicated shapes

## Fabrication technologies are not

- ...the Star Trek replicator
- ...as fast as the best manufacturing solutions for bulk manufacturing
- ...as fast as your 2d printer
- ...inexpensive
- ...nice to touch (material range is limited)

**But** they can do a lot of interesting things

---
## Additive Vs Subtractive

- Additive printing puts down material, building up the object layer by layer
  - Some are done with extruded plastic or other material
  - Others are done with powders that are sealed together (powder printers)
- Subtractive removes materials from around the object

# Laser  Cutting

This week, we will focus on a particular kind of fabrication: Laser Cutting

---
exclude: true

# Exclude after planning is done

- Bring scissors 
- Have a demo of building something from flat to 3D ready to show (including the wood with the punched out pieces so they understand how to layout SVGs in Tinkercad)

# How Laser Cutting works

We're using a [Glowforge](https://glowforge.com/). 
- It takes SVGs as input
- It can engrave, cut, etc
- We're providing plywood, 3mm thick [double check with calipers]
- We will not engrave during lab, it slows things down too much, but we may cut

---
# What can you do?

.left-column40[
![:img Illustration of cutting scoring and engraving first with those words and then with stars. Cutting cuts a hole; Scoring outlines something; and Engraving burns it into the wood, 70%, width](img/3dprinting/laser-Cut-Score-Engrave.png)
]
.right-column60[
Cutting: Makes a hole

Scoring: Doesn't cut all the way through. Use a different color

Engraving: Burns. Can do greyscale.
- Images.  Make sure they're not too dark. 
- Add in a drawing program after Tinkercad
]

---
# How we will create SVGS

First create a design in TinkerCAD (or other CAD software if you know it well)
- You should group everything together that is touching
- Place it carefully. The base plane will determine what is part of the final SVG
- We will not engrave during lab, it slows things down too much, but we may cut
- Export it as SVG (demo)
   - Include mm as units

---

# Your process

1. Measure your object
2. Make an svg of your design
3. Print it on paper
4. Cut it out and check your measurements AGAIN
5. Iterate
6. Upload it to our drive
7. Sand, glue & paint (if you want)

# First print: On Paper

# Measuring

.left-column50[![:img Calipers stretch the width of four fingers and show a measurement of about 76mm , 100%, width](img/3dprinting/measuring.jpg)
]

---
# Other Important Measurements

The amount of wood removed by the laser cutter as it burns through the wood.

Should always test for each new type of wood and wood thickness

[Instructable](https://www.instructables.com/How-to-Adjust-for-Wood-Thickness-and-Kerf-on-a-Las/) on how to do this

Only an issue if you're making a box or something else that has to assemble

Use calipers to measure!

# Next class

Come prepared to design: 
[TinkerCad](https://www.tinkercad.com/dashboard)

[Adobe Illustrator](https://www.adobe.com/products/illustrator.html). Best for most tasks if you have it

[AutoCAD](https://www.autodesk.com/products/autocad/overview?term=1-YEAR&tab=subscription) (free for students). Probably overkill

[Inkscape](https://www.autodesk.com/products/autocad/overview?term=1-YEAR&tab=subscription) (free). Best free option

Can even use powerpoint

---
# Now: time to start your design

(Pen and paper first)

---
class: center, middle, inverse
# Other Thoughts (if time)

---
## Pause and discuss

Try to think of some everyday objects that could be made more accessible (customized through DIY making)

(think pair share)

Crafters with Disabilities

## Example: Knitters with disabilities

We interviewed 16 disabled knitters about their motivations, process, needs, and experiences of bias

- 11 Blind or Low-Vision
- 7 Motor-impaired
- 3 with Cognitive Impairment

We collected data from six forums to extend our sample size and complement our interviews with more motor and cognition related data

---
## Making Patterns Accessible

Pattern accessibility was a frequent problem for disabled knitters
- Forum posters mentioned over 40 different pattern formatting guidelines to make patterns more accessible
- Not just about nonvisual access

For example P14-MC, who wrote out patterns in detail, said:

.quote[...if it says you need to go and knit 16 rows, I’ll write out [all of them] and then I’ll mark them off as I go. (P14-MC)]

.footnote[MC indicates motor and cognitive impairment]

---
## Making Craft Accessible

Four participants (P1-MVC, P2-V, P5-M, P11-V) reported difficulty with small gauged looms

Both circular knitting needle and loom knitters experienced difficulty executing a purl stitch

.quote[...when I purl …[I] have to push my thumb down like that to get
tension… And so there’s a lot more pinching for me… and that
definitely causes discomfort the fastest. (P3-M)]

![:img A crochet robot with a prosthetic leg and a big heart, 70%, width](img/3dprinting/prosthetic-leg-robot.png)

]
.right-column[
The results of knitting solved accessibility problems for some knitters
- Patterns for toy robots with disabilities to increase the inclusion and representation of disability in the knitting community (P10-M)
- Tops for wheelchair users with a shorter back and longer front

.quote[if your sweater is too long in the back [and] goes underneath you, it's hard to transfer. (P14-M)]

]
---
## Community Ableism

Participants primarily participated in communities of knitters to learn, as support networks, project collaborators, and to increase inclusion.

Bias included assumptions about ability and even concerns about image, such as one forum poster experienced when a pattern designer *“didn’t like the idea of a wheelchair being in the shot.”*

## Domain Experts

**A lot of research is needed here**

- Full power of software engineering
- Equivalent of end user programming
- Production and personalization of interactive systems
  - Modularity 
  - Requirements Specification
  - Hybrid Control over AI based systems (e.g. optimization)
