Your first 10 prints: what to print to actually learn

Skip the Benchy after the first one. The 10-print progression that teaches you support, orientation, tolerance, and failure recovery.

The default advice for new 3D printer owners is "print a Benchy." Print the Benchy once, sure — it's the standard calibration print. After that, most people drift into printing random things from Thingiverse without a learning plan.

Here's a 10-print progression that builds actual skill. Each print teaches one specific concept and prepares you for the next.

Print 1: Benchy

The 3D Benchy boat is the universal calibration print. 25 minutes (or 5 minutes on a Bambu). What to look for:

• The bow chines should be crisp, not droopy (overhang quality)
• The cabin roof should be flat, not sagging (bridging)
• The hull walls should be straight, not concave or convex (z-axis)
• The chimney should be round, not oval (X/Y calibration)

If any of these fail, you have a calibration issue to fix before printing more. Most 2024 printers pass the Benchy fine out of the box.

Print 2: A calibration cube

20mm cube. Measures dimensional accuracy. Print it, then measure X, Y, and Z with calipers. If any dimension is more than 0.2mm off from 20mm, your printer needs adjustment.

This teaches: dimensional accuracy matters, and printers aren't all calibrated the same.

Print 3: A cable comb or earbud holder

First "useful" print. Small (under 2 hours), forgiving on quality, teaches you that 3D printing is for making things you'll use. This is where the hobby clicks for most people.

Recommended models: "Cable Drop" by SunshineKid (Thingiverse 53192), or any earbud holder.

Print 4: A storage container with friction fit lid

Two-part print. Teaches tolerance. The lid has to fit snugly enough to stay on but loose enough to remove.

Print the box and lid as separate prints. If the lid doesn't fit, scale it by 0.5% smaller and try again. This is real-world dimensional tuning.

Recommended: "Stackable Storage Containers" (search Printables).

Print 5: A model with required supports

Up to this point, your prints have been support-free or had simple supports. Now print something that requires supports — a model with overhangs steeper than 60° from vertical.

Examples: A figurine with an outstretched arm, a tool holder with a hook, a model with a chimney over a window.

This teaches: how supports attach, where they fail, how to remove them, how surface quality differs on supported vs unsupported sides.

Print 6: A part that needs orientation thinking

Print a wrench. The right orientation is flat — the part lies down on the bed. Print it standing up first (badly) so you understand why orientation matters. Then print it correctly.

This teaches: layer adhesion is the weak axis of FDM prints. Orienting parts so that stress is across layers, not perpendicular to them, dramatically changes strength.

Print 7: A multi-material or multi-color print

If you have an AMS (Bambu) or manual color-change capability, print something with two colors. Manual color change: print a name tag with white background and black letters using "pause at layer" features in your slicer.

This teaches: 3D printing isn't just shape — it's also material change, color, and finish.

Print 8: A functional load-bearing part

Print something that has to hold weight. A hook for a backpack. A wall mount. A bracket for a shelf.

Print it with 40% infill (heavier than the 15-20% default for decorative) and 4 perimeters (more than the 2-3 default).

This teaches: infill density and wall count are the main variables for part strength.

Print 9: A part with tight tolerances (mechanical fit)

Print a hinge, or a pair of gears, or a snap-fit assembly. The challenge is making moving parts that actually move.

Recommended models: print a working hinged box, or a "print-in-place" articulated dragon (any of the common designs).

This teaches: clearance is everything. 0.2mm gaps don't work; 0.4mm gaps do. Most slicers underrun their dimensions slightly, so a 0.4mm modeled gap prints as 0.35mm.

Print 10: A failed print, on purpose

Sometime in the first 10 prints, you'll have a failure — adhesion loss, layer separation, nozzle clog, stringing. When it happens, don't panic. Note the symptom, read about it (3D printing communities have catalogued every failure mode), and fix it.

This teaches the most important skill: 3D printing is not a press-a-button-and-walk-away technology. You'll diagnose problems for the rest of your printing life.

What to skip in the first 10 prints

• Long prints (over 6 hours). Long prints fail in the same ways short prints fail, but you waste more filament and time.
• Models with thin walls (under 1mm). They're a calibration test, not a useful skill yet.
• Models requiring tree supports. Tree supports work great in modern slicers, but learn standard supports first.
• Engineering materials. Stick with PLA for the first 20+ prints.
