Ready to get your hands dirty? Here’s the step-by-step breakdown to ensure your functional prints don’t just look good but work hard.

🔬 Material Matters: Choosing the Right Filament for the Job

Material choice is the foundation of functional printing. Here’s a quick rundown:

Material	Strength	Flexibility	Heat Resistance	Ease of Printing	Best Use Cases
PLA	Moderate	Low	Low (~60°C)	✅ Easy	Prototypes, low-stress parts
PETG	High	Moderate	Medium (~80°C)	✅ Moderate	Tools, mechanical parts
ABS	High	Moderate	High (~100°C)	❌ Challenging	Automotive, heat-resistant parts
Nylon	Very High	High	High (~120°C)	❌ Difficult	Gears, hinges, wear parts
Polycarbonate (PC)	Very High	Moderate	Very High (~140°C)	❌ Difficult	Structural parts, impact resistance
TPU (Flexible)	Low	Very High	Medium	✅ Moderate	Flexible parts, grips

Source: Formlabs Materials Guide

Pro Tip: Dry your filament before printing, especially PETG and Nylon, to avoid brittleness and poor layer adhesion.

📐 Design for Durability: Engineering Your Prints for Strength

Your design is only as strong as its weakest point. Here’s how to beef it up:

Increase Wall Thickness: Aim for 3-6 perimeters (walls). More walls = thicker, stronger shells.
Avoid Sharp Corners: Use fillets and chamfers to reduce stress concentrations.

Optimize Layer Orientation: Print parts so stress aligns with layer lines, not across them.
Add Ribs and Supports: Reinforce flat or thin areas with internal ribs.
Simplify Geometry: Complex thin features can be fragile.

From the trenches: Our team found that increasing perimeters from 2 to 4 on a wrench handle made it feel like a store-bought tool, echoing advice from the Prusa3D forum.

🎛️ Print Settings for Performance: Optimizing Your Slicer

Settings can make or break your functional print. Here’s what to dial in:

Setting	Recommendation	Why?
Perimeters (Walls)	3-6	Thicker walls = stronger parts
Infill Density	20-50%	Supports structure; higher for stress areas
Infill Pattern	Cubic, Adaptive Cubic	Stiffness with less print time
Layer Height	0.15-0.2 mm	Balance detail and strength
Print Speed	40-60 mm/s	Slower speeds improve layer bonding
Print Temperature	Max recommended for filament	Better layer adhesion and tensile strength
Cooling Fan	Moderate or off for ABS/Nylon	Prevent warping and layer separation
Over-Extrusion	+3-5%	Improves inter-layer bonding (at cost of surface finish)

Heads-up: Avoid 100% infill for strength; it can cause brittleness and cracking. Instead, focus on walls and smart infill patterns.

✨ Post-Processing Power-Up: Enhancing Your Functional Prints

Don’t stop when the print finishes! Post-processing can transform your part from good to great:

Annealing: Heat parts in an oven to relieve internal stresses and increase strength (works well with PLA and PETG).
Epoxy Coating: Apply a thin layer of epoxy resin to seal and strengthen surfaces.

Sanding and Polishing: Smooth rough edges to reduce stress risers.
Vapor Smoothing: For ABS, acetone vapor smoothing improves layer bonding and surface finish.
Reinforcement: Embed metal rods or inserts for extra strength in critical areas.
