00.08_6D_Objectify_3D Printer Research 2

Do Now: Think about the 3D printer research you completed. In your notebook, answer the following:

What kind of manufacturing method is 3D printing?

What is the "ink" - ie. the material - that FDM printers use?

What are other important parts of an FDM printer?

What is one brand of FDM printer?

Today’s Agenda:

1. Objectified Documentary - next 6 minutes and reflection questions

2. Research 3D printers & SLS Printing

Learning Objective: YWBAT describe Selective Laser Sintering.

Essential Question: How is SLS different from FDM printing?

A Documentary about Industrial Design

Directed by Gary Hustwit

Tiered Assignment:

• Complete all parts for as much as 90%.
• Earn the final 10% by staying on task throughout the period.

Your assignment (due at end of the period):

• Research the Selective Laser Sintering (SLS) method of 3D printing. Identify differences between SLS & FDM.

You will:

1. Pick up your Chromebook.

2. Go to the Tech & Design folder in your Google Drive and open "00.08_Research - 3D Printing SLS_Your Name".

3. Read the instructions carefully and answer all questions within.

Basic Laptop Rules:

1. No headphones - except when watching assigned videos.

2. Only use the laptop assigned to you.

3. Carry the laptop by the base (not the screen).

4. On task - doing so is worth 10% of your overall grade on the assignment.

Design: Lesson Six

Group folders

• Work will be turned in and returned to you through the folders.
• Each activity or worksheet that we do has a specific amount of time in which to do it.
• Place the assignment in your Group's folder when the time is called. It will be graded and returned to you in the same folder in our next class.

Ergonomics: the science of design so that people can things easily and safely.

Research 3D Printers

Watch carefully, answering the questions on the worksheet as you watch.

Quick Intro to 3D Printers

Printing Methods!

Laser Sintering - Powder

Fused Deposition Modeling - Filament

• A plate is placed within a powder bath. A laser fuses specific parts of the powder that is on the plate.
• The plate drops, a new layer of powder is spread over the fused cross-section and a new layer is fused atop the previous layer.
• Professional, industrial uses only.

• Filament is extruded through a nozzle onto a build surface one 2D layer (x & y axis) at a time.
• Third dimension is added to the model by movement in the z direction by either the extruder nozzle or the build surface.
• The filament can be made from a variety of materials.
• Professional and consumer grade models.

Stereolithography - Liquid Resin

• A resin is poured into the printer and a plate is placed on top of the resin bath.
• An ultraviolet laser is directed into the bath and - one layer at a time - the model is built from the top down.
• Excellent detail, high resolution levels.
• Professional and consumer grade models available.
