3D Printing

Welcome to 3D Printing at POLSER Elementary

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.



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.

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.
