3D Printing Fishing Lures: The Ultimate Guide
Design, print, and fish with custom lures that outperform store-bought baits. Learn the best filaments, slicing settings, and design secrets for 3D printed fishing lures.
Explore MaterialsWhy 3D print your own fishing lures? Customization, cost savings, and the ability to tweak designs for specific fish species. Whether you're targeting bass, pike, or saltwater game, 3D printing gives you total control over weight, action, and color.
Best Filaments for 3D Printed Lures
Choosing the right material is critical for durability, buoyancy, and printability. Here are the top options for 3D printing fishing lures:
| Material | Key Properties | Best For | Price (1kg spool) |
|---|---|---|---|
| PETG | Impact-resistant, UV-stable, slight flexibility | All-around lures, crankbaits, topwater | $25–$35 |
| ABS | Hard, durable, good heat resistance | Deep-diving crankbaits, saltwater | $20–$30 |
| Nylon (PA12) | Extremely tough, abrasion-resistant | Pike/musky lures, jig heads | $45–$65 |
| TPU (flexible) | Soft, rubber-like, realistic action | Soft plastics, swimbaits, trailers | $30–$50 |
Pro tip: PETG is the most beginner-friendly and offers an excellent balance of strength and ease of printing. For topwater lures, use a lightweight filament like PLA+ (though less durable, it's great for prototyping).
Design Tips & Slicing Settings
Creating effective 3D printed fishing lures requires attention to weight distribution, wall thickness, and infill. Here's what works:
Infill & Weight
Use 20–30% infill for buoyancy. Add cavities for lead weights or BBs to fine-tune sink rate.
Wall Thickness
Set perimeter walls to 1.2mm (3 layers) for durability against teeth and rocks.
Layer Height
0.16mm for fine details (scales, gills), 0.2mm for faster prints with good finish.
Supports & Orientation
Print at 45° angle to reduce supports. Use tree supports for complex overhangs.
Always print a test piece to check for balance and buoyancy before committing to a full batch. Many anglers print a hollow version first, then seal with epoxy for added strength.
Post-Processing: Painting & Sealing
A well-finished lure catches more fish. Here's how to get professional results:
- Sanding: Use 200→400→800 grit to smooth layer lines.
- Primer: Apply a plastic primer to fill micro-gaps and improve paint adhesion.
- Paint: Airbrush or rattle-can with UV-resistant acrylics. Add eyes and scale patterns with stencils.
- Clear Coat: Seal with 2-part epoxy or UV-cured resin for a glossy, durable finish.
For hard baits, consider adding rattles or internal chambers to enhance sound and vibration.
Best 3D Printable Lure Designs
From topwater poppers to deep-diving crankbaits, 3D printing opens a world of possibilities. Here are the most effective designs:
- Poppers & Walking Baits: Great for bass and pike; print with a cupped face.
- Crankbaits: Add internal rattles and a diving lip for depth control.
- Swimbaits: Jointed designs with flexible TPU sections for realistic swimming action.
- Jig Heads: Print with a recess for a weight and a barb for soft plastics.
- Flies & Spoons: Lightweight for fly fishing or trolling.

Frequently Asked Questions
Can 3D printed lures catch fish?
Absolutely. With proper design, materials, and finishing, 3D printed lures are as effective as commercial ones. Many professional anglers use them for custom colors and actions.
What filament is best for saltwater?
Nylon (PA12) and PETG are highly resistant to saltwater corrosion. Avoid PLA in saltwater as it can degrade over time.
Do I need a special printer?
No. Most standard FDM printers with a 0.4mm nozzle work well. For flexible filaments (TPU), a direct-drive extruder is recommended.
