Have you ever wondered if you could make fishing lures with 3D printed molds? Well, yes, you can, with some caveats. You will need to use the right type of 3D printing filament to withstand the heat of the soft plastic, and 3d printed molds will not be as durable or long lasting as aluminium ones, but it is certainly possible to employ a 3D printer to make your own molds for all kinds of lures.

If you love custom fishing equipment, 3D printing can be a great way to customize your gear, allowing you to experiment with fishing lures over time until you find the perfect solution to catch the most fish.

What is a 3D Printed Fishing Lure Mold?

A 3D printed lure mold is the basis for creating duplicate copies of a lure you have designed. You can create a 3d printed mold of any shape or size, allowing you a lot of flexibility in the design of your fishing baits.

Usually a 3D printed mold would be created in two parts, allowing you to easily separate the halves once the plastic used for your lure has hardened.

A benefit of 3D printed molds is that they can easily be iterated upon. So if you make a mistake in the original, you can easily change it without a large expense. This makes 3D printed molds an excellent option for prototyping molds that will later be made in aluminium.

How much will it cost to 3D print a lure mold? That depend on how complex it is, the size and number of the lures etc.

What Are the Different Types of 3D Printed Molds Possible?

 3D printed molds can come in almost any different style depending on what you would like to create. This will often come down to what type of fish you are trying to catch, as some types of bait are more suitable than others for specific fish species.

Here are some of the common fishing lure mold types you could choose to create:


The square bill crankbait is one of the best topwater lures. It is a great fishing lure for shallow water. The lure allows you to move the bait around at different speeds or depths, and usually has a lip that allows it to stay underwater. Crankbait can be made of metal or soft plastic called plastisol. The crankbait is often designed to replicate a spoon or bullet shape.


This is another great topwater bait. Spinnerbaits get their name from the propeller attached to them that makes them imitate a swimming fish. This type of fishing lure is suitable for catching predatory fish like bass.

Spoon Lures

This form of fishing lure is convenient for catching bigger fish. They come in a concave shape and give off a shiny look that attracts fish.

Rattle Popper Fishing Lures

This kind of fishing lure is suitable for freshwater fishing. It’s somewhat unique as it can be used with live bait, and you can move the bait easily in the water through different angles.

How to Design 3D Lure Molds?

To design a lure mold for 3D printing, you need to be familiar with the use of computer aided design (CAD) software.

CAD software is expensive, and it has a steep learning curve. For this reason, many beginners looking to make a custom aluminum fishing lure mold will outsource their CAD designs to a professional CAD company like us. Here at J-CAD we specialize in creating 3D CAD designs from scratch based on your requirements. All we need is a simple drawing with dimensions to get started. It can be surprisingly affordable to get us to do your designs. We can then send you .STL files for you to 3D print yourself, or we can do the 3D printing for you. We can also help you create molds in aluminium and even mass produce your lures if you want to sell them at scale.
