INTRODUCTION
3D printing sounds like a concept straight out of a modern-day science fiction movie. However, it’s real and growing increasingly popular, transforming everything from manufacturing to the medical field. But what is it? How does it work? This guide will walk you through, explaining the magnificent workings of 3D printing, why it’s exciting and worth exploring even if you’re a beginner. Don’t worry; this guide is crafted to make this intricate technology easy to understand even for amateurs.
WHAT IS 3D PRINTING?
3D Printing, also known as additive manufacturing, is a production process that forges three-dimensional solid objects from a digital file. Unlike the traditional manufacturing process which cuts away the unnecessary material to form the desired object, 3D printing adds layers of material until the object takes form — hence the name, additive manufacturing.
The concept of 3D printing dates back to the 1980s, spearheaded by Charles Hull, who invented a technique called ‘stereolithography’. It could interpret 3D models on the computer, which would later be transformed to physical models. Today, 3D printing is used across several industries, including automotive, construction, medical fields, and even in culinary arts as food printers.
HOW IT WORKS/HOW TO GET STARTED
1. First, you will require a 3D digital model of the object you intend to print. You can create your design using Computer-Aided Design (CAD) or 3D scanner software.
2. Once your design is ready, you can transfer it to the 3D printer. Noteworthy to mention, the connected computer must have 3D printing software installed to communicate with the printer effectively.
3. The printer will then start to form the object by adding layers of material, one on top of the other until the whole object is formed.
4. When the process is completed, you will have your physical object identical to your 3D digital model.
WHAT YOU NEED TO PRINT
To get started with 3D printing, you’ll need a 3D printer, obviously. Some affordable and user-friendly options for beginners include the Creality Ender 3 V2 and the Anycubic i3 Mega. You’ll also require a 3D design software (which often comes with your 3D printer). If not, freely available ones include TinkerCAD and FreeCAD. A computer is needed to design your object and to communicate with the printer.
TIPS FOR BEGINNERS
1. Start small – It’s exciting to print big, but start with small, simple designs to avoid wasting materials.
2. Familiarize yourself with your software – Each software can be different. Spend time learning the ins and outs of whichever one you go with.
3. PATIENCE – 3D printing is a slow process. It requires time.
4. Experiment – Don’t be afraid of making mistakes. It’s part of the learning process.
5. Safety – Suppliers might provide gloves and masks, use them to avoid touching hot surfaces or inhaling potentially harmful gases.
RESSOURCES UTILES
There are numerous online resources you can refer to deepen your knowledge or troubleshoot dilemmas that you may encounter during the 3D printing process:
– 3D Print Beginner: Offers heaps of tutorials, print settings, and more.
– Thingiverse: A library of varied 3D models.
– YouTube: Channels like Makers Muse and 3D Printing Nerd make brilliant beginner-friendly guides.
GLOSSARY
1. Filament: The ‘ink’ for 3D printers, usually made from PLA or ABS.
2. PLA: A widely used, easy-to-print biodegradable material.
3. ABS: A strong and durable printing material that is a bit more complex to print with.
4. Extruder: The ‘pen’ that the printer uses to ‘draw’ the design.
5. Bed leveling: The process of ensuring the bed, or print surface, is completely flat before beginning a print.
NEXT STEPS
Armed with your basic understanding of 3D printing, it’s time to enter the practical world. Start with a simple 3D design, practice, and gradually move on to complex designs. Don’t hesitate to reach out to the 3D printing community on platforms like Reddit or Thingiverse. Above all, remember, as with any knew knowledge or skill, practice makes perfect. Enjoy the thrilling and rewarding process of bringing your digital creations into the physical world. Keep learning, keep experimenting, and let your creativity flow.
