INTRODUCTION
Hey there, welcome to the exciting and creative world of 3D printing! Maybe you have seen a 3D printed object, or perhaps you’ve heard people talk about it and wondered, “What is it and how does it work?” Trust me, I’ve been there! No worries, you’ve come to the right place. 3D printing is a remarkable technology that’s transforming not only industries but it also provides exciting opportunities for individuals like you and me. Get ready, because in this beginner-friendly guide, we’re going to dive into what 3D printing is, how you can start and even create your very own 3D printed object!
WHAT IS 3D PRINTING?
3D Printing, also known as additive manufacturing, is a process of making three dimensional solid objects from a digital file. Unlike traditional manufacturing methods where material is removed through cutting or drilling, in 3D printing, the object is created by laying down successive layers of material until the object is formed.
The history of 3D printing can be traced back to the 1980’s when it was mostly used for industrial applications. However, thanks to advancements in technology, 3D printers have now become more affordable, user-friendly, and are now used in various sectors including healthcare, fashion, education and more. Imagine making personalized jewelry, replacement parts for gadgets, or even food and houses; with 3D printing the possibilities are endless!
HOW IT WORKS / HOW TO START
Ready to begin your 3D printing journey? Let’s start with how it works:
1. Design Process: This is your starting point. You either design your own 3D model using software like AutoCAD or Tinkercad, or download ready-made designs from websites like Thingiverse or MyMiniFactory.
2. Slicing: After the design is completed, you need to convert it into something the 3D printer can understand. This process called slicing, is done using slicing software. The software takes your design and breaks it down into layers that the printer can build.
3. Printing: Once the file is sliced, it is sent to the printer, where the magic happens. The printer reads each slice from the software, then builds the object layer by layer.
WHAT YOU NEED TO PLAY (SUPPLIES, GEAR, SETUP)
For 3D printing you need a few tools:
1. 3D Printer: There are different types of 3D printers like FDM (Fused Deposition Modeling), SLA (Stereo Lithography), but as a beginner, a FDM printer like the Creality Ender 3 is a great starting point.
2. 3D Printing Filament: This is the material the printer uses to create the object. Popular types of filament are PLA and ABS.
3. 3D Modeling Software: As mentioned before, software like AutoCAD or Tinkercad can be used to design your own models.
TIPS FOR ABSOLUTE BEGINNERS
1. Start Simple: Start with a simple design, something like a keychain or a phone stand. This will help you understand the process better.
2. Be Patient: 3D printing is not an instant process. Depending on the complexities of the design, it can take several hours to print an object.
3. Maintenance is Key: Regular maintenance of your 3D printer can ensure that it runs smoothly and lasts longer.
4. Experiment: Don’t be afraid to test different materials, settings, and design software.
5. Learn from Mistakes: Things might not always go as planned, but that’s okay. Each failure is an opportunity to learn.
HELPFUL RESOURCES
1. Websites: Thingiverse, MyMiniFactory
2. YouTube Channels: 3D Printing Nerd, Maker’s Muse
3. Forums: 3D Hubs, Reddit’s 3D printing community
GLOSSARY
1. Slicing: The process of converting a 3D design into layers that the printer can build.
2. Filament: The material that the printer uses to print the object.
3. Extruder: The part of the printer that pushes the filament into the hotend to be melted and then deposited to form the printed object.
4. Infill: This is the internal structure of your print. More infill makes prints stronger but uses more filament.
5. Bed Leveling: The process of making sure that the printing surface is perfectly level.
NEXT STEPS
Now that you know what 3D printing is and how to get started, your next step will be to get your hands on a 3D printer and start experimenting. Have confidence, be patient, learn from your mistakes, and most importantly, have fun. The world of 3D printing is your creative playground. Enjoy the journey!
