    Type 316L is another established structural metal. It is an austenitic stainless steel with low carbon content to limit complications in welding. Despite this, care is still required when welding the end product. Tensile strength is approximately half of 17-4 PH, but elongation at break is substantially larger. Heat treatment does not strengthen 316L. 316L exhibits exceptional resistance to corrosion, especially from chlorides, and maintains its strength even at high temperatures. It's commonly used in structural applications at high temperatures or in the presence of chlorides.

    Stronger than ABS, yet more brittle, Polycarbonate is the material of choice where shock loads are less likely than constant loads and more strength is required than ABS provides. Polycarbonate is also transparent to RF radiation, making it ideal for antenna covers, containers, and a variety of structural components.

    Polycarbonate 20% GF

    For projects which need to increase strength even further, glass polycarbonate composites are an option. At double the strength, three times the modulus, and a notably higher impact resistance, this material is ideal for thin walled structures, structural components, and any other application where more strength and rigidity is needed.

    Nylon 6/6

    With a high surface hardness, high temperature tolerance, and better strength than Polycarbonate (but lower toughness), Nylon 6/6 is the next step in trading impact resistance for static strength. This is the material of choice when a high melting point plastic is required and scratch resistance is still desired, or when strength and stiffness are key. Ideal use cases include thin cosmetic covers or underhood components.

    30% GF Nylon

    For increased strength and heat resistance, glass reinforced Nylon is also available. This is the weakest of the composites, but still stronger than any plastic besides the ULTEMs, and it is even more resistant to heat than pure nylon. This is the material of choice for underhood components and other applications which require the best strength possible while maintaining the temperature resistance of Nylon.


    Like all Acetals, Delrin exhibits good temperature resistance along with exceptional lubricity, surface hardness, and abrasion resistance. It also exhibits better stiffness than polycarbonate; making it ideal for high performance engineering components such as gears, joints, and fasteners. As a result, it sees heavy use in the automotive industry.


    High Density Polyethylene has a limited strength, but a high elongation to failure, strength to weight ratio, and toughness. It also possesses high chemical resistance, meaning it can be easily disinfected or used in contact with acids. Its low melting point and softness make it easy to machine, weld, and cast. As such, it's ideal for mass produced containers in contact with both benign and highly acidic materials. It's also commonly used for cutting boards, machined parts, and tank linings.


    Similar in many ways to HDPE, Polypropylene is used in similar applications. However, Polypropylene has a higher melting point, allowing it to be used in microwaveable containers, and is able to withstand autoclaving conditions. It possesses high lubricity which prevents it from being glued effectively. Because of this, its relatively low melting point is leveraged to weld it instead. Combined with its high strength to weight ratio, fatigue resistance, and chemical inertness which it shares with HDPE, it sees use in reclosable containers, ropes, piping, and clothing.

    Clear Acrylic

    Acrylic exhibits strength similar to Nylon, but with lower toughness and a better surface hardness. It is also highly transparent, and can be used as a replacement for glass. In many cases, it serves as a more economical alternative to polycarbonate when toughness is not as critical or the presence of Bisphenol A could be an issue. Artwork, intraocular lenses, biomedical implants, and windshields are all applications for this material.

    AZ31 is a low strength, low density Magnesium alloy for applications which require a good strength to weight ratio, specific modulus, and weldability. It is also highly corrosion resistant. Magnesium is the lightest of the structural metals, and is particularly useful when buckling is a concern. Its low density means parts made from AZ31 will be thicker in order to have the same strength as their aluminum counterparts. This material is appropriate for very light components such as camera frames, tripods, backpacking gear, and aerospace parts.

    Stainless Steel / 304/304L

    Type 304 stainless steel is a moderate strength, highly ductile, general purpose austenitic stainless steel suitable for gears, structural components, and other structural uses in moderately corrosive environments. 304L is a low carbon variant that can be welded as carbide precipitation is negligible.

This material sees heavy use in the aerospace, petrochemical, and food industries for structures, containers, and other types of parts.

    Steel Alloy / 4140

    4140 is a low alloy steel with high impact and abrasion resistance as well as toughness. It also has great fatigue strength and decent resistance to atmospheric corrosion. This makes 4140 suitable for structures, gears, chains, and functional components in mildly corrosive environments. It has good weldability, and maintains reasonable strength up to 600°F.
