INTRODUCTION
Hello there! We’re about to dive into an exciting and revolutionary technology that is revolutionizing several sectors of our lives ─ from the medical field to manufacturing, and even the arts. This is 3D printing! The essence of this guide is to demystify what seems to be a complex technology and provide clear, easy-to-understand insights into how you can get involved too. Ready to take the plunge into this fantastic world of additive manufacturing? Then, let’s get started!
WHAT IS 3D PRINTING?
3D Printing, also known as additive manufacturing, is a process that creates solid objects from a digital file by adding material layer by layer until the object is fully formed. This technique stands in contrast to traditional subtractive methods, where material would be cut or drilled away to achieve a specific form. The beauty of 3D printing is that it allows for the creation of complex shapes and designs that are impossible with traditional manufacturing methods.
The concept of 3D printing emerged in the 1980s, and it’s been improving and expanding into various sectors ever since. Ranging from printing human organs for transplantation to creating jewelry and even building homes, the possibilities seem limitless!
HOW IT WORKS OR HOW TO GET STARTED
To give shape to your imagination with 3D printing, you would need a digital 3D model. This model can be created using computer-aided design (CAD) software, or downloaded from an online database. Once the 3D model is ready, it is sliced into thin layers by a separate software, and sent to the 3D printer. The printer then prints the object layer by layer until the final product is formed.
Starting with 3D printing might seem daunting at first glance, but don’t worry! With some practice and experimenting, you will get the hang of it.
WHAT YOU NEED TO PLAY
To begin your 3D printing journey, you’ll require a few essential tools:
1. 3D Printer┃This is the core tool. There is a wide range of 3D printers available to suit various budgets and needs.
2. 3D Modeling Software┃You’ll need this to design your 3D model. Examples include Tinkercad, Blender, and AutoCAD.
3. Filament┃This is the plastic used by the printer to create your objects. The most commonly used types are PLA and ABS.
4. Slicing Software┃This software slices your design into layers for the printer. Examples include Cura and Slic3er.
TIPS FOR ABSOLUTE BEGINNERS
1. Start Simple┃Start with simple designs to understand the capabilities of your printer.
2. Calibration Is Key┃Before you start printing, make sure your 3D printer is well-calibrated.
3. Experiment with Settings┃Try different speed, temperature and layer settings.
4. Learn from Others┃Use online communities and forums for tips, tricks, and troubleshooting.
5. Patience Pays Off┃3D printing can be time-consuming. Do not rush the process.
HELPFUL RESOURCES
Useful platforms like Thingiverse offer a wide range of free 3D models to print. YouTube channels such as Maker’s Muse and 3D Printing Nerd provide excellent educational content. Forums like RepRap and 3DPrintBoard are great communities to engage in.
GLOSSARY: COMMON TERMS EXPLAINED
1. CAD┃Computer-Aided Design
2. Filament┃The plastic material used in the printing process
3. FDM┃Fused Deposition Modeling, a common type of 3D printing technique
4. Slicer┃Software that slices 3D models into layers
5. Print Bed┃The surface upon which your printer makes the 3D print
NEXT STEPS: WHERE TO GO FROM HERE
Now that we have provided you with a beginner’s guide to 3D printing, it’s your turn to take the initial steps. Start by learning a CAD software, visit a local 3D printing shop, or join a 3D printing group in your local community or online. And remember, 3D printing is a journey filled with trials and errors. But, practice makes perfect! So go on, embark on this 3D printing adventure, the possibilities are endless!
