Design
Using a CAD (computer aided design) software, these floating stickbaits are created to mimic the natural movements of NZ baitfish. Multiple different size, shape and density variations were trialled before settling on a final design.
Material
The stickbaits are printed from 100% recycled PLA (polylactic acid), a bioplastic made from renewable sources such as corn starch or sugar cane, not oil. PLA cannot be recycled kerbside in NZ, the recycled filament used is sourced from Kiwifil in Tokoroa, NZ.
3D Printing
A filament of extruded recycled PLA is used to recreate the lure as seen in CAD. Each lure is individually 3D printed which allows air pockets to be added, something that is very difficult to achieve by injection moulding. These air pockets are crucial to achieve a floating stickbait and to distribute weight which results in the stickbaits swimming action. There is minimal waste when 3D printing as only the lure itself is printed, and any waste or failed prints are returned to Kiwifil to be re-recycled.
Thru Plates
The through plates are cut from 316 2B 2mm thick stainless steel. This steel has vastly superior corrosion resistance to chlorides and acids which are found in seawater.
Weight Balancing
In order to achieve a side to side type swimming action, the centre of drag must further towards the front of the lure than the centre of gravity. This is obtained by adding extra weight to the lure using steel or tungsten, there is no lead in these lures.
Adhesion
The lures are printed in halves and bonded together with cyanoacrylate glue, also known as superglue.
Epoxy
An epoxy resin coating is applied to each lure for added protection, while PLA is not home compostable it is damaged under constant exposure to seawater. Epoxy resin gives the lure a tough, water-resistant coating, ensuring it can withstand prolonged exposure to seawater and also restricts water absorption into the PLA which can affect the lures density and hence swimming action.
