3D Printing for Beginners

How to Use a 3D Printer like ‘Magic’.

3D printing can seem like science fiction than it sounds.
We need to follow some simple steps-
with essential information on data files and software. With your own 3D printer, you can produce exactly the parts and products that you, and maybe only you, need. This book will guide you through your first steps in 3D printing at home.

Convert this model into printer instructions
Send these instructions to your printer
Begin printing.
Many popular 3D printers come with several designs ready to print. These are often included as a set of instructions for your printer to follow and can be the quickest way to get a print going on your machine.

The results of tests using a small fleet of Raspberry Pi-controlled cars by Cambridge University researchers were presented at the International Conference on Robotics and Automation in Montreal in June.

What Is and Where to Get STL Files for 3D Printing.

Stereolithography

2019 Best Free STL File Viewer Tools

According to Wiki,”Stereolithography (SLA or SL; also known as stereolithography apparatus, optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers to link together to form polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1986. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive”.
Stereolithographic apparatus (SLA) converts liquid plastic into solid objects.
SLA, or stereolithography, is a method of 3D printing that utilizes a laser and resin. The first 2D pattern becomes the first layer of the print, usually suspended from an upside-down build platform.
STL (an abbreviation of “stereolithography”) is a file format native to the Stereolithography CAD software created by 3D Systems. This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing.

How do I make STL files for 3d printing?

7 Free S Editors + How to Edit and Repair STL Files

Step 1

Open STL file and convert it to solid model
Open FreeCAD and create a new document by clicking on File > New.
Click File > Import and select the object you want to modify. …
Change your workbench to Part.
Select the imported object in the Model window.
Now click on Part > Create shape from the mesh.

Step 2

Edit STL file
Switch your workbench to Part Design.
Click on any face you want to add or remove material, so it shines green.
Now click Create Sketch.

Step 3

STL Repair
FreeCAD  features an extensive mesh repair tool:

Select Meshes > Analyze > Evaluate & repair mesh.

Step 4

Export as STL file
To export your object as an STL file again, select the last feature in the model tree.  Then click on File > Export and select Mesh formats…..

Slicing and G-Code

There are two major types of software that will allow printing a (good ready-to-print) 3D model file. A so-called slicer takes a3D drawing and translates this model into individual layers. It then generates the machine code that the printer will use for printing. 3D printing.

There are free slicing tools they convert the model into G-code. Some are,
Slicer, Slic3r, Cura, Repetier-Host.

What is g-code?

How to 3D Print

Now we already chose model, sliced it into G-code, and ready to print. To start printing, your machine needs to know the G-code instructions required for every step. Sending your G-code to your printer varies by model, but there are several common methods:

Save the files to an SD card
Control the printer with your computer
Use a 3D printer control system such as a Raspberry Pi.

Installing and configuring Octopi on a Raspberry Pi controller for wireless printing and monitoring. All files and programs listed below. Micro SD card also required. I used an 8GB for extra storage.

Raspberry Pi 4

If your printer supports it, saving G-code to an SD card is often the simplest way to print things. Printers with SD card support almost always have display and control buttons. Navigate to your G-code file and choose the print option. Insert the plastic filament and ensure the printer is set up following the manufacturer’s instructions.

Connecting a 3D printer to your computer over USB lets you control it using the slicing tool of your choice. This option works well but requires your computer to remain on and connected to the printer for the duration of the printing.

Finally, OctoPi is a Raspberry Pi-based 3D printer controller. This is a good way to control your printer over the network but requires some initial configuration.

According to your options, you should soon hear the zzzzz sounds of your 3D printer giving you ultimate surprise? It is your first print! This is an exciting time, and it is so awesome to watch the whole process.
