3D Print Academy — Free Interactive 3D Printing Courses & Games

Learn 3D printing by playing, not reading. The 3D Print Academy by 3D Printing Perth brings you 101 hands-on interactive labs: melt filaments in a virtual hotend, fight warping, hunt strings, spin printed threads and dial in the perfect first layer. Every module below runs right in your browser — no sign-up, no downloads, just tap and learn.

Whether you run a Bambu, Prusa, Creality or any FDM printer, these interactive 3D printing lessons cover temperatures, layer heights, supports, retraction, bed adhesion, moisture, tolerances and more — the same knowledge our Perth repair bench uses every day.

🌱 Level 1 — Beginner

Meet the machine — melt, squish, and understand your printer from day one.

  • What is 3D Printing? — The full FDM pipeline: 3D model -> slice into layers -> melt filament -> stack layers -> object
  • Inside the Hotend — Parts of a hotend: heatsink+fan, heatbreak, heat block, heater cartridge, thermistor, nozzle
  • Hotend Temperature Lab — Every filament has a softening point (Tg) and a print window
  • Hot Car Lab — Prints deform in hot environments - creep under load near Tg
  • Infill Explorer — Infill = the skeleton inside the print; walls carry most of the strength
  • Layer Height — Layer height = resolution vs speed trade-off; 0.08mm to 0.32mm with a 0.4 nozzle.
  • Walls & Shells — Outer walls carry most strength; more walls > more infill for tough parts.
  • Overhangs & Supports — Gravity means >45deg overhangs droop; supports fix it but scar the surface.
  • First Layer Matters — 90% of failed prints start at layer 1; squish must be just right.
  • Filament Family — Personality of each material: PLA the friendly all-rounder, PETG the tough one, TPU the gymnast, PCL the ki...
  • PCL = Kid-Safe — PCL melts at just ~60C - warm water, not fire
  • Colour-Changing Filament — Thermochromic and photochromic filaments change colour with heat/sunlight.
  • Print Orientation — Layer lines are weak seams; orientation decides where it breaks.
  • Meet the Slicer — What a slicer does: turns a model into machine path (G-code) + settings that matter.
  • File Formats — STL = shape only; 3MF = shape + settings + colours; STEP = engineering precision.
  • Bed Adhesion Basics — Why corners lift (warping) and how beds/temps/brims fight it.

🔧 Level 2 — Intermediate

Slicing and quality — the sliders and settings that fix real prints.

  • Slicer Lab — Layer height x speed x walls x temp interact - find combos that balance quality, time, filament.
  • Speed vs Quality — Why fast prints get ringing and mushy corners (acceleration, not just speed).
  • Retraction & Stringing — Ooze = strings; retraction pulls filament back between moves.
  • Cooling Fan — Part-cooling fan freezes overhangs and bridges; too much = weak layers (PLA) / cracks (ABS).
  • Bed Levelling Sim — Turn four (or mesh) knobs to get an even first layer.
  • Z-Offset Tuner — Fine-tune nozzle height; read the first layer like a pro.
  • First-Layer Doctor — Diagnose first-layer symptoms -> fix.
  • Support Types — Normal vs tree vs snug supports; scar tissue vs easy peel.
  • Brim / Raft / Skirt — Three bed helpers and when each earns its filament.
  • Temperature Tower — How pros dial in the perfect temp per filament brand.
  • Flow Rate — Extrusion multiplier fixes over/under-fed prints.
  • Pressure Advance — PA/Linear Advance sharpens corners by managing pressure in the nozzle.
  • Ironing — Top surfaces can be smoothed by re-passing the hot nozzle.
  • Bridging — Short gaps can bridge without supports; long spans sag.
  • Vase Mode — Spiral continuous mode: one wall, Z steadily rising, seamless vases.
  • Seam Placement — Every loop starts/ends somewhere - the z-seam; options hide or align it.
  • Adaptive Layers — Slicer can use thin layers on curves, thick on straight walls.
  • Infill Patterns Deep-Dive — Force direction experiments: grid vs gyroid vs honeycomb vs cubic.
  • Tree Support Lab — Tree supports grow around the model using less filament and touching less.
  • Multicolour Intro (AMS) — Multi-material systems swap filaments and purge between colours.

🚀 Level 3 — Advanced

Under the hood — hotends, motion, moisture, resin and firmware.

  • Printer Anatomy — Every major assembly of a modern printer: frame, motion (rails/belts/steppers), toolhead (extruder+hotend),...
  • Hotend Dissection — Full breakdown: nozzle, heat block, heatbreak cartridge, heater, thermistor, silicone sock.
  • Nozzle Size Guide — 0.2 to 0.8mm: detail vs strength vs speed.
  • Nozzle Materials — Brass for everyday; hardened steel mandatory for carbon fibre; ruby/tungsten exotic.
  • Direct vs Bowden — Where the extruder lives changes retraction, speed and flexibles support.
  • Extruder Gears — Hobbed gears grip and push; tension matters; skipping = clicking.
  • Motion Systems — Belts, linear rails, rods, wheels - precision sources and slop sources.
  • Belt Tension — Loose belts ghost; over-tight wears bearings and motors.
  • Input Shaping — Accelerometers let firmware cancel resonance ringing.
  • Moisture & Drying — Filaments are sponges: nylon/TPU worst, PLA mild
  • Hygroscopic Ranking — Rank filaments by water appetite.
  • Storage Guide — Bags, desiccant, dry boxes, printers-as-dryers.
  • Annealing — Bake PLA/crystalline parts for heat resistance; they shrink/warp.
  • Enclosure Effects — Warm still air stops ABS/ASA warping and fusing drafts.
  • Resin vs FDM — Two technologies, different jobs: detail vs size/price/material range.
  • Resin Exposure — UV exposure time controls detail vs stickiness.
  • Resin Workflow — Print -> wash -> cure; safety gear at every step.
  • Bed Surfaces — PEI/PEO/PET/glass: grip hot, release cold (or the reverse).
  • Adhesives — Glue stick, hairspray, Magigoo: when plates need help.
  • Filament Dryer Lab — Each stocked dryer model + right recipe per material.
  • RFID Smart Spools — Bambu spools carry chips: auto settings + remaining count.
  • Filament Recycling — Purge-to-filament machines, PLA compost truth vs hype.
  • Fumes & Safety — PLA mild, ABS/ASA styrene - ventilate; resins need gloves.
  • Firmware Landscape — Marlin vs Klipper vs Bambu - what changes for the user.
  • Klipper & Macros — Printer.cfg, macros, why tinkerers love Klipper.

🏆 Level 4 — Professional

Engineering, strength, tolerances and failure forensics.

  • Material Selector — Decision tree: strength? heat? flex? outdoor? food-safe? -> right filament (incl. coming ABS/ASA/PA/PC).
  • CF Filaments — Carbon-filled = stiff, matte, dimensionally stable; needs hardened nozzle.
  • Anisotropy — Layer bonds are weaker than the layers; parts are laminates.
  • Bend Test Sim — PLA snaps, PETG bends, TPU bounces, PC refuses.
  • Tolerances — Holes shrink; mating parts need clearance.
  • Printing Threads — Real threads printable; orientation and clearance rules.
  • Press-Fit Calculator — Interference math for bearings and pins.
  • Thermal Expansion — Plastics grow with heat; assemblies creak in the sun.
  • UV & Outdoor — PLA chalks and embrittles in sun; ASA is the outdoor king.
  • Chemical Resistance — Which filament survives oil, fuel, acetone, bleach.
  • Cost Calculator — Filament + electricity + time (+ failure risk) = true cost.
  • HS PLA Science — High-speed PLAs stay viscous-stable at 300-600mm/s.
  • Flow Rate Math — Layer width x height x speed = mm3/s; every hotend has a limit.
  • Heat Creep — Heat creeping up the heatbreak softens filament early -> jam.
  • Clog Doctor — Systematic unclogging: cold pull, needle, teardown.
  • Stringing Fixes — Three usual suspects: temp, retraction, moisture.
  • Warping Fixes — Shrinkage vs adhesion physics; material + bed + environment triangulation.
  • Layer Shift Causes — Belt slip, collided head, skipped steps, loose pulley.
  • Under-Extrusion — Starved lines from flow, temp, partial clog, or tension.
  • Blobs & Zits — Pressure spikes at starts/stops ooze out as blobs.
  • Ghosting & Ringing — Vibrations echo sharp corners onto surfaces.
  • VFAs — Vertical fine artefacts trace to extruder micro-steps and rails.
  • Elephant Foot — First layers squish outward when too hot/too close.
  • Failure Gallery — Real failures from our repair desk, each diagnosed.
  • Design Rules — Minimum walls, hole sizes, bridging limits, tolerance defaults.
  • Overhang Design — Chamfers, fillets and teardrop holes avoid supports.
  • Part Strength — Ribs, gussets and rounded corners beat thicker walls.
  • Print Farm Basics — Fleet thinking: scheduling, QC, spool logistics, service pricing.
  • Fire & Electrical Safety — Fuses, firmware protections, smoke alarms, enclosure materials, never-leave-ABS-unattended rule.
  • Maintenance Schedule — Nozzles, beds, rails, belts, PTFE - intervals and symptoms.
