Printer types, side by side

See how bed-slinger, CoreXY and delta printers move, compare direct drive with Bowden, and find the printer that fits you.

How each type moves

Pick a printer type and watch which parts move. The whole difference comes down to what is heavy and what is light.

A1 geometry comes from the supplied CAD assembly. The added spool and continuous filament strand show the supply path into the head. Axis movement and added supply hardware are illustrative.

The bed moves back and forth (Y), the print head moves left and right (X), and the gantry rises (Z).

Speed
Affordability
Compactness
Strengths
  • Cheapest and simplest
  • Huge community and upgrade parts
  • Easy to repair
Trade-offs
  • Heavy bed limits speed on big, tall prints
  • Tall thin parts can wobble
  • Usually open-frame

Examples: Ender-3, Prusa MK4, Bambu Lab A1

Direct drive vs Bowden

The extruder pushes filament into the hotend. Where it sits changes what you can print.

Simplified teaching models: motors, pulleys, belts and drive wheels are enlarged for visibility. Belt paths show the drive layout, not an assembly guide.

The motor and gears ride on the print head, right above the nozzle.

A short filament path means precise retraction and reliable flexible filaments such as TPU. The head is heavier, which can limit top speed.

Parts that matter

Four parts decide most of what your printer can and cannot do.

Hotend

Heats and melts the filament. All-metal hotends reach 300 °C and handle nylon and carbon-fibre filaments.

Nozzle

0.4 mm is the standard. 0.2 mm gives fine detail, 0.6 mm prints faster. Use hardened steel for abrasive filaments.

Build plate

Textured PEI grips well and gives a rough underside, smooth PEI gives a glossy one, glass is flat and needs glue.

Firmware

Marlin runs most budget printers, Klipper offers speed and input shaping, Bambu firmware is closed but polished.

Which printer fits you?

Answer three questions and get a starting point. It is a guide, not a verdict.

  • An open frame is fine for your materials.
  • Direct drive or Bowden both work.

Check yourself

Pick an answer for each question.

1. On a CoreXY printer, what moves in the Z direction?

2. You want to print flexible TPU on a budget printer. Which extruder helps most?

3. Which printer type needs a circular bed?

Figures such as temperatures and drying times are typical ranges. Always check the label on your own spool and your printer manufacturer's guidance.
