00.10_7C_3D Printer Review_3D Printer Research SLA

Learning Objective: YWBAT describe Stereolithography.

Essential Question: What sets SLA apart from the FDM and SLS printers?

• Form of Printer Material: Filament

• Solid filament is heated into a liquid and deposited onto a build plate by an extruder.
• The print is build one layer at a time - from the bottom up.

• Advantages: Affordable

• Form of Printer Material: Powder

• Basic Process: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 previous layer and a another layer of the model is fused on top of the previous layer.

• Capable of fine detail and a wide variety of materials, including metal.

• Professional, industrial uses only.

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 Stereolithography (SLA) method of 3D printing, and answer the questions within the Google Doc 00.10

You will:

1. Pick up your Chromebook.

2. Go to the Tech & Design folder in your Google Drive and open "00.10_Research - 3D Printers SLA_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 Ten

Do Now: Answer the following in your notes (2 minutes):

Yesterday we learned about SLS (selective laser sintering) 3D printers.

1. What is the form of the material used in SLS printers? How is it different from what FDM (fused deposition modeling) uses?

2. Which printer is capable of creating more complex objects - SLS or FDM?

Which is capable of printing in metal?

Which is more affordable?

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.

Today’s Agenda:

1. 3D Printing Methods - FDM & SLS quick review

2. 3D Printing Research Day 3 - SLA Printers (due by the end of the period)

Quick Review of 3D

Printing Methods!

Laser Sintering - Powder

Fused Deposition Modeling - Filament

Stereolithography - Liquid Resin

• Form of Printer Material: Liquid Resin

• Basic Process: 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.
