It takes something special to stand out in the busy world of 3D printing filament developers and suppliers these days, so that says a lot that Fortis3D has succeeded. The Canadian startup, based in Brantford in southwestern Ontario, develops high-quality filament formulations for the hobbyist, consumer, automotive and appliance markets.

Led by a small but dedicated team of polymer engineering specialists, Fortis3D is advancing its mission to improve the quality and performance of thermoplastic 3D printing materials. In fact, quality is the company’s guiding principle: not only does Fortis3D develop new filament formulations with improved properties, but it also has a rigorous quality control system in place to ensure that every spool it ships meets and even exceeds the standards.

As the company states on its website: “Our manufacturing facility is GMP compliant [Good Manufacturing Practice] certified and registered to ISO 9001:2015 which ensures a class-leading level of consistency in diameter, ovality and colors from batch to batch.

The Fortis3D Wallet

The filament maker currently has eight materials in its portfolio, which is divided into three subcategories: Essential, Advanced and Industrial. In its Essential range, ideal for hobbyists and for functional prototypes, you will find a good selection of PLA-based filaments, including BioDuro PLA, a food biomaterial with improved properties; BioDuro Metallic PLA, which features an eye-catching metallic finish; Pilates PLA, a soft touch filament with rubbery properties; and Lignum PLA, which is made from 25% recycled pine wood fibers for a wood-like finish.

In the Advanced category are three high strength filaments suitable for functional applications. They are: SnapPrint PA, a low-strain nylon copolymer characterized by high strength and elasticity; Ignis PLA, a temperature resistant PLA formula; and SnapPrint PP, a lightweight, chemical-resistant polypropylene. Last but not least is the industrial filament, Nylon 6, a highly ductile and tough PA6 suitable for applications in the electronics, appliance and automotive industries.

We have to add that there are eight filaments available – for now. Fortis3D continuously develops and works on new materials to expand its range and meet the needs of various industries and applications.

To better understand how Fortis3D’s materials compare to other filaments on the market, we take a close look at two of its filaments, BioDuro PLA and SnapPrint PA. Fortis3D has conducted a number of competitive analyses, which demonstrate how their filaments compare to other filament brands.

BioDuro PLA provides toughness

First, let’s look at BioDuro PLA. Part of the company’s Essential line, BioDuro PLA combines key features of PLA, such as good printability and mechanical strength, with increased toughness. Manufactured in a GMP certified facility, the filament is also FDA approved for food contact and has been designed to be UV resistant.

PLA filament differs from other PLA, PLA+ and Tough PLA filaments on the market in several ways. For one, while most PLA filaments are made from pure resin, Fortis3D has developed a proprietary compound for its BioDuro PLA. This formulation increases toughness and flexibility. “It has the best balance of toughness and strength, as well as one of the highest breaking elongations on the market,” the company says.

Fortis3D Filament

BioDuro PLA has lower tensile strength than other premium PLAs, but as Fortis3D adds, it compensates for this drop in toughness. Specifically, BioDuro PLA has 10% less tensile strength but almost triple the elongation. In comparison, other premium PLA filaments tested by the company demonstrated high tensile strength but low elongation, resulting in fragile 3D printed parts.

Like most filaments, the true potential of BioDuro PLA is unlocked with the right print settings. Fortis3D discovered that the best toughness and elongation could be achieved when printing at high temperature above 240°C. In a sample component printed with a nozzle temperature of 250°C, the material demonstrated the ability to stretch over 20 times more than competitive filaments before breaking.

Fortis3D BioDuro PLA filaments comes in a wide variety of colors and is available in 1kg spools for $35.

SnapPrint PA reduces the risk of warping

Next, SnapPrint PA, Fortis3D’s high strength and elasticity nylon copolymer. The material, which is suitable for a range of tooling and functional applications, such as gears and bearings, is also known for its resistance to warping on the print bed. Like many other filaments from Fortis3D, SnapPrint PA is FDA approved for food contact and has good UV resistance.

Comparing SnapPrint PA to other nylon filaments, Fortis3D places special emphasis on the excellent strength and ductility of the filament. In fact, the company claims its nylon has “the best balance of strength and ductility,” while maintaining good printability. Other nylon filaments, on the other hand, have either demonstrated higher tensile strengths at yield point and significantly lower breaking strengths (as well as lower elongation at break), or resistance to significantly lower tensile and yield strength and higher elongation at break.

Fortis3D SnapPrint PA

SnapPrint PA achieved the best balance with 49.5 MPa tensile strength at break, 41.1 MPa tensile strength at break, and 275% elongation at break. In other words, the Fortis3D test print not only retains its strength better before breaking, but it also takes longer to break. We can take a closer look at the comparison in the table below.

In addition to its good strength and ductility, SnapPrint PA has a low coefficient of friction and high wear resistance, as well as an HDT/B rating of 125°C. SnapPrint PA is available in natural and black colors for $55 per 0.75 kg spool. Ultimately, the material and other filaments in the SnapPrint series were developed with the goal of improving the printability of traditionally difficult-to-print materials.

Fortis3D now serves the US and Canadian markets

Currently, Fortis3D’s advanced thermoplastic filaments are available to customers across the United States and Canada, although special requests can be made for large international orders. With a view to international growth, Fortis3D is looking to partner with resellers in North America and Europe who can bring its unique filaments to more customers. The company also offers custom color services for large filament orders.

Again, this is just the beginning for Fortis3D. The young company was founded in 2020 and has already made an impact with its unique and proprietary compounds. Be sure to watch this space and follow the company for additional filament formulations.
