ISS Space Station 8th Grade _Briarhill MS

Zach and Joey created and printed this 3D model. 

Print time was 2 weeks all day - every day.

PolyPrinter

After using a printer that took 10 hours to print a single object, this printer is quick in comparison.  After the first time I saw it several years ago at ESC Region 11, I have longed for this printer.  I wanted to use ABS filament because it has a smoother print finish. The features that are mandatory for using ABS are a heated print bed and a full enclosure. The HEPA filter allows you to use ABS in a small "enclosed" area (my office). It is a great little printer. Keep in mind that it has a steeper learning curve than the MakerBot. I think the learning will be fun and worth every minute!

What sets this printer out from the crowd? Customer Service!!

PolyPrinter's Educator Recommendation - "We recommend educators new to 3D printing start with a PolyPrinter 229. It is reliable, fast, and easy to use. All the instruction needed is provided in our initial training, which is 2-3 hours of personalized training on PolyPrinter hardware and software."

Software for Polypinter and related materials

I love this machine!  The customer support gets 10 stars!!!  

You can use it with a Mac, but I highly suggest a dedicated windows machine.

What materials can the PolyPrinter print in?

PLA, ABS, Nylon, and NinjaFlex.

NinjaFlex requires a separate extruder due to its physical properties. The NinjaFlex extruder costs $250.

Makerbot Mini

Buy:

Currently this is the only printer on our approved bid list. You should order:

The Polyprinter is not on the LISD bid list however, many institutions are having great luck with it.

Before you buy the printer have concrete standards to support your purchase. The real learning happens in the software. It is free. 

Getting Started (MakerBot Mini)

  1. Download: Download MakerWare Desktop –you must use Safari or Firefox http://www.makerbot.com/desktop
  2. Create an account for: Thingiverse  - http://www.thingiverse.com

Have a generic username and password that you can share with your kids who have created files. You can also pick files form this location and just print. It is a good demonstration of a 3D printed object.

 

Makerbot in the Classroom 

 Read the MakerBot Reference Guide:

Unbox printer

  1.  The Mini takes PLA filament. Double-check the type of filament you purchased prior to loading it into your printer.
  2. After the physical setup of the printer is complete (see reference guide) for the MakerBot Replicator Mini:
  3. Turn on the MakerBot and the computer. (Plug into the laptop you loaded the software on and plug into an outlet.)
  4. You may be asked to update the firmware – follow the prompt in the software.
  5. Load filament (page 23 in Reference Guide). A mistake here is very expensive!! Watch the film. The hose that you feed the filament through has a black clip on it. The clip needs to be near the end of the hose. It takes a lot of force to move the clip up and down the hose.

For the first print, see page 18-19 of Reference Guide for step-by-step directions.

Welcome to 3D Printing at POLSER Elementary

What is 3D printing?
It is the action or process of making a physical object from a three-dimensional digital model, typically by laying down many thin layers of a material in succession.
Vocabulary will not be taught in isolation. Some of the vocabulary words are located in the glossary for you to reference. 
 
Videos - Due to terms of use for YouTube, please watch this with your parent or with your teacher.

Cars:

The 1st fully printed 3D car will be in the market April 2019 - 

A new type of electric car will hit the market next year, and rather than the thousands of parts found on a Tesla, it will have less than 100 parts. The two-seater LSEV takes just three days to make, according to the car's manufacturer. The LSEV is produced by XEV Limited, a start-up firm from Hong Kong which has a design center in Italy and production bases in China. It will hit the Asian and European markets first. XEV Limited will start mass producing the car soon with the expectations that it will hit the market in April 2019 at a price of $10,000.

Plane parts: Boeing Instead of storing parts at their various hubs, or requiring parts to be shipped to them, possibly causing extensive delays, the company could just pull up a specific file for a part that’s needed, and have it fabricated within minutes or hours wherever they have a printer available.

Clothing

Parts that are no longer available:  When you have 100-year-old classic cars or modern, hand-built custom cars, how do you make spare parts? Watch Jay Leno and his Chief Engineer, Jim Hall, as they explain the process of 3D scanning to 3D printing from 3D Systems for end-use parts for Jay’s car collection.

Parent Permission and Tutorials

Notes to parents:

  1. Parent Letter 

    • Parent's please print and sign the parent letter
    • Create your child's account: https://www.tinkercad.com (This is a web-based account, thus you do not need to download the program.  Their work will be saved on Tinkercad's servers.)
    • Give your child the username and password for your Tinkercad Account the teacher may not perform this task for you. You may sign them up on your cell phone.

After you have a username and password, you may begin the tutorials. Success requires access to a mouse. This will work on a Chromebook, however, you will have better success with a larger screen found on one of these options: MAC, MAC AIR, or PC. You will be given time to work on these in class.  The Lewisville Public Library has a 3D printer. You may submit your print project here:

If you make something you wish to have printed Frisco public library has a printer. They also have classes. Your parents may join the library as a nonresident for $50.00.  https://friscolibrary.com/

Rules you must know!

This site will explain that the surface Quality is not always what you see in your drawing.

https://i.materialise.com/en/3d-printing-materials/abs/design-guideTolerance -

Anything can be "drawn" in 3D on a digital canvas, but not everything can be 3D printed.

Tolerance

 https://www.youtube.com/watch?v=TYuLVN3YHw8

15 X 15 hole Insert sizes:

Squares (starting on the left)

Think about Orientation of the object before you start building it.

Another type of tolerance is used in 3D printing during the export. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. We advise choosing 0.01 mm for a good export.

Rule of 45 degrees

A 3D printing overhang is any part of a print that extends outward, beyond the previous layer, without any direct support.

The maxim degree of overhang can't exceed 45 degrees with out support material. A simple solution for this object was to turn it

on the side to print it.

This is exactly the same file.

Printing an object where the bottom will not fully touch the surface of the print bed.

Object on the left did not touch the print bed fully because

The sides were curved upward. So far, 1 hour of cleaning

with a knife has been performed.

Object on the right had perfect contact with the print bed.

Notice no cleaning will be required.

Wall Thickness

Problems linked to wall thickness are by far the most common reasons why some 3D models are not printable.

Design Thinking

 

"Difficult situations breed astonishing results." Jeffrey Veen

Essential Question

It can sometimes feel overwhelming to be a kid when there are so many problems in the world. After all, kids can't really make a difference, right? Wrong! Kids are making a positive change in the world every day. Now you have the opportunity to make a change. Choose a problem you care about and create an original solution! Let’s get started and make a difference!

* Empathy is using your imagination to step into someone else’s shoes.

Goal - Empathize with another person to find out what is really needed to improve their current situation. Often it seems easier to think about what we need to improve our situation, but helping others and learning to understand their needs and struggles helps you:

Day 2 and 3_ 3D Drawing and Tinkercad

__________________________________________________________________________________

Examples to review together.

Draw your project on grid paper. To have the correct dimensions use precise measurement. You will duplicate your drawing in Tinkercad.

Include:

____________________________________________________________________________

You have already gone through these tutorials.  Do you have questi0ns about how they completed any of the tutorials?

Tutorials     https://www.tinkercad.com

In a painting or drawing, you use guidelines and techniques to give your work a feeling of depth.

     https://www.arthipo.com/artblog/en/drawing-techniques/basic-principles-of-perspective-drawing-2.html

Drawing in 3D in Tinkercad actually uses an additive and subtractive process.

     https://pinshape.com/blog/tinkercad-tutorial-with-dotm-chaoscorete

_______________________________________________________________________

Let's work on a few skills that the tutorials did not cover.

Align objects:

  1. Place a sphere and a cube on the work plane
  2. Select both  - To select all - Cntrl +A  OR hold down the left click button on a mouse and draw around the objects you want to choose.
  3. Click on the align tool - you have several options - hover over each option and there is a preview

Creating pattern - 

  1. Drag a triangle onto the work plane
  2. Select the shape (do not unselect the shape)
  3. Choose option duplicate while the cube is selected
  4. Use keyboard arrows to shift left or right, or use the arrow to change the z-axis (I am going to rotate this example in place.)
  5. Click duplicate repeatedly
  6. Changing the orientation of your view will allow you to continue your pattern in a new direction.

Rotation in place

    

Trick?  Yes, make it shorter on the duplicate prior to moving with the keyboard arrows.  Then, duplicate!

Creating a circular pattern-

  1. Place W on workplace
  2. Click duplicate
  3. Drag a copy of the W / rotate it  (You might want to zoom in closely to be sure the shapes are aligned like you would like for them to be. Hold down the control key on the keyboard and tap the plus sign.)
  4. A circle has how many degrees?
  5. Use interior snap it will auto-fill the circle exactly / or you can divide the number you want into 360 degrees 

Shape generators-

Review - 

  1. How do you make sure your object is on the work plane?
  2. What is the greatest angle you may have on any part of a shape and still print? 
  3. Which of these items will print and why will it print? 

They are the same grouping of objects, why did I check different views to check if it will print?

    

Will this object print?  Why or why not? (Hint: What is the maximum angle within an object?)

How can I fix it?

 

X, Y, Z axes: an axis is an imaginary line about which an object can rotate, which also serves as a fixed reference for measuring position. In a Cartesian coordinate system, the z-axis is perpendicular to both the x-axis and y-axis and usually represents depth or the third dimension. You can lift objects up from the workplane and along the z-axis by using the black arrow pointing up from the center of the object.

3D printing - Glossary of Terms

Align: to place or arrange (things) in a straight line. To use the Align tool, select at least two objects by Shift left-clicking on them or by dragging a box around them. Once selected, click on the Align icon at the top. Simply move your mouse over a node (the black dots) to preview the move.

Angle: a figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. It also measures the amount of turn an object is rotating, for example 45 degrees or 90 degrees (also called a "right angle.")  You can not print an object with greater than a 45-degree turn.

Diameter: a straight line going through the center of a circle connecting two points on the circumference.

Dimensions: a measurable extent of some kind, such as length, width, or height. In its simplest form: a line describes one dimension, a plane describes two dimensions, and a cube describes three dimensions.

Duplicate: to make or be an exact copy of. To duplicate an object, use Ctrl + D and then drag it out or use the arrow keys.

Exportto convert a file into another format than the one it is currently in. For example, you must export your design in order to print it. Tinkercad also allows you to "share" your design in the form of a PNG image file. (a png file is a flat file that can't be 3D printed.) You will export in an STl or and OBJ 3D FILE FORMAT depending upon the 3D printer you will use.

Fabricate: to construct or manufacture. To "make" your design. You can make almost anything through 3D printing or laser cutting.

Flip: a tool that allows you to create the mirror image of an object or to flip it along the x, y, or z-axis. Use the Flip icon after you have selected the object. Use Flip and Duplicate together to create complex designs more efficiently.

Gallery: a collection of creations grouped together. Creations in the Tinkercad gallery typically can be copied and tinkered for analysis, modification, and inspiration. You can publish your design by changing the setting to public when you are ready for an audience.

Group: to combine two or more shapes into a part. Do this by selecting them and then choosing the Group icon at the top.

Handle: (Nodes) in graphics programs - the little squares that appear on the shape when you select it that allow you to resize it by pulling and pushing them.

Hole: a tool used to subtract from a solid shape.

Import: to bring a file from a different program into the one you're using. In Tinkercad, you can import STL files in order to analyze and build upon the 3D designs of others, or SVG files in order to add 2D images like logos and patterns to your designs.

Millimeter: a millimeter is 1/32 or 0.039 of an inch. This is the default unit of measurement in Tinkercad.

Pan: to rotate a camera on the horizontal or vertical axis. Use the right mouse button to do this.

Part: one or more shapes that have been grouped together.

Perpendicular: at an angle of 90 degrees to a given line, plane, or surface.

Plane: a flat surface with no thickness.

Primitive (or shape): a starting point or building block for 3D design. These shapes can be added, subtracted, and combined with one another to build just about anything. They include Cube (Box), Cylinder, Tube, Sphere, Torus, and Cone.

Rotate: to move in a circle around an axis or center. When you select an object, the arrows are for rotation. You can rotate on any of the planes.

Ruler: you know what this is in real life! You can access this handy tool for measuring by dragging it out on the workplane. This can enhance your design by allowing you to see an object's exact location on the workplane, and also by making it easier to manually set measurements.

Scale: to change the size of an object so that its dimensions are proportional to the original size. You can do this by holding down the Shift key while pushing and pulling the handles to resize.

Shortcutcomputer keys that help provide an easier and usually quicker method of navigating and executing commands in computer software programs. Here is a link to the Tinkercad shortcut keys.

Workplane: the large, blue grid where you create your designs. You can drag out new workplanes onto the surfaces of your shapes for easier stacking and more precise measuring.

X, Y, Z axes: an axis is an imaginary line about which an object can rotate, which also serves as a fixed reference for measuring position. In a Cartesian coordinate system, the z-axis is perpendicular to both the x-axis and y-axis and usually represents depth or the third dimension. You can lift objects up from the workplane and along the z-axis by using the black arrow pointing up from the center of the object.

Zoom: to move a camera from a long shot to a close-up gradually. Use the wheel on the mouse to do this.

Printer: PolyPrinter - http://www.polyprinter.com/
What filament and printer will be used for the project?
ABS filament. 
 ABS  It is used to print Functional Parts Medium strength Density 1010 kg/m³[6]  Flexibility Medium Durability High Difficulty to print Medium  Print tempt. 210 - 250 Print bed temperature 50 - 100
ABS Filaments are made from a mix of three different chemicals - polybutadiene is mixed with a polymerizing mixture of butadiene and styrene to form the finished plastic. 
A huge advantage of ABS over PLA is that it’s soluble in acetone - the stuff in nail varnish remover - and so two separately printed pieces can be easily fused together or varnished with just a few drops. Moisture will eventually be harmful to ABS, but it’s resistant in the short term - a lego brick isn’t instantly ruined when it gets wet, after all.
