  • 1984: Charles Hull invents stereolithography (SLA), the OG of 3D printing (source).
  • 1990s: Stratasys (Scott Crump) brings FDM (Fused Deposition Modeling) to market, making 3D printing more accessible.

From Industrial Secret to Desktop Revolution

  • 2005: The RepRap project launches, aiming for a self-replicating 3D printer. Cue the open-source explosion!
  • 2010s: Desktop 3D printers like MakerBot and Prusa i3 start popping up in homes, schools, and hackerspaces.
  • Today: 3D printing is everywhere—from prosthetic limbs to printed houses.

Why the Sudden Boom?

Fun Fact: The first 3D printed object? A tiny cup, printed by Charles Hull. We’ve come a long way from plastic shot glasses!

🔬 What Exactly Is 3D Printing? (Additive Manufacturing Demystified)


Video: What Is 3D Printing and How Does It Work? | Mashable Explains.








If you’ve ever wondered, “What is 3D printing, really?”—you’re not alone! Let’s break it down.

The Basics

  • 3D printing = Additive manufacturing: It creates objects by adding material layer by layer, as opposed to subtractive manufacturing (think: carving a statue from a block).
  • Digital to physical: You start with a digital 3D model, then the printer brings it to life.

“Machines build parts and products one layer at a time. You can make pretty much anything you can dream up with 3D printers.” — Xometry

Key Ingredients

  1. A 3D Model: Designed in software (CAD) or downloaded from Thingiverse.
  2. Slicing Software: Converts the model into printable layers (G-code).
  3. The Printer: Follows the G-code to build your object, layer by layer.

Why Additive Manufacturing Rocks

  • Complex shapes? No problem! Print objects impossible to make with traditional methods.
  • Less waste: Only use what you need.
  • Customization: Make one-of-a-kind items, from custom-fit shoes to personalized phone cases.

🛠️ How Does 3D Printing Work? Step-by-Step Guide


Video: 3D PRINTING 101: The ULTIMATE Beginner's Guide.








Ready for a peek behind the curtain? Here’s how we go from “I want that!” to “I made that!” in the world of 3D printing.

Step 1: Design Your Model

Step 2: Slice It Up

  • Slicing software (e.g., Ultimaker Cura, PrusaSlicer) converts your model into “slices”—thin layers the printer can understand.
  • Adjust settings: Layer height, infill, supports, and more.

Step 3: Prep the Printer

  • Load your material: Filament (PLA, ABS, PETG, etc.), resin, or powder—depending on your printer.
  • Level the bed: Trust us, you’ll want to get this right. (Ask us about the time we forgot—hello, spaghetti monster!)

Step 4: Print!

  • Send the file to your printer via SD card, USB, or Wi-Fi.
  • Watch the magic: The printer builds your object, layer by layer. (Pro tip: The first few layers are crucial.)

Step 5: Post-Processing

  • Remove supports: Carefully snip away any extra material.
  • Finishing touches: Sand, paint, or assemble as needed.

Step-by-Step Table

Step What You Need Pro Tips
Design CAD software or 3D model Start simple—think keychains, not Iron Man suit
Slice Slicer software Preview layers to catch errors early
Prep Printer Filament/resin, clean bed Level, level, level!
Print SD card/USB/Wi-Fi Watch the first layer like a hawk
Post-Process Tools, sandpaper, paint Take your time for best results
