What is the strongest material to 3D print?
Carbon Fiber Reinforced Nylon: This combines the strength enhancement of carbon fiber additives with the toughness and durability of nylon, making it generally the strongest 3D printing material.
Polycarbonate (PC) delivers high tensile strength along with high impact and heat resistance. It's widely seen as one of the strongest 3D printing filaments.
Triangular Infill: Triangular infill is the strongest infill pattern because triangles are the strongest shape. They are least likely to deform and provide the best support structure behind the walls of the part.
PETG filament
It has a strong impact and abrasion resistance and can sustain higher temperatures compared to PLA. Because of its excellent properties and relatively low price, PETG is commonly used in 3D printing.
Direct Metal Laser Sintering (DMLS)
Right after the 3D printing process the parts are fully functional (heat-resistant, strong and durable). In fact, the parts are even better than those cast with regard to density, and that translates into their mechanical properties.
If you're just getting started or need something that prints quickly and consistently every time, you should start with a filament like PLA (polylactic acid)or Tough PLA. For larger prints, PLA is the most reliable and serve a wide range of applications, such as concept models and functional prototypes.
In terms of strength and durability, PLA is considered a relatively strong material, but it has some limitations. While it can be stiff and strong, with a tensile strength of 50 MPa, it is also more brittle than other materials such as ABS or PETG.
PP. PP (Polypropylene) is a lightweight and flexible material, but don't let that fool you. In fact, PP is a very durable 3D printing material with great impact and fatigue resistance.
PETG has higher impact strength than PLA, reducing the risk of fracture. PETG has higher hardness than PLA, making it more able to resist abrasion.
PEEK (PolyetherEtherKetone) is a high performance thermoplastic and the strongest 3D printer filament with a tensile strength of approximately 7250 PSI. Its excellent strength-to-weight ratio with a Young's modulus similar to human bone allows it to be used in medical applications.
What is the heaviest 3D filament?
Rapid 3DShield Tungsten has the highest density of all existing filaments, even higher than GMass™, allowing parts to be made up to 4 times heavier than with conventional materials (PLA or ABS).
ABS is a bit more durable, is about 25% lighter, and has four times higher impact resistance. ABS does require more effort to print than PLA because it's more heat resistant and prone to warping.
ABS Filament
Acrylonitrile butadiene styrene (ABS) is common for creating high-impact products, such as plastic parts for toys, car parts, and cases for electronic devices. This filament is highly durable, and its impact resistance makes it perfect for industrial applications.
Titanium is the most-used metal in the additive manufacturing industry. It is widely employed in the medical, aerospace, automotive, and electronic industries, among others. Titanium and its alloys have high mechanical strength. They also offer better corrosion resistance than stainless steel.
While terminology is often mixed, thermoplastic polyurethane (TPU) is the most commonly used flexible material within the 3D printing industry.
However, materials that burn rather than melt at high temperatures cannot be processed safely by sintering or melting, but can be used when extruded through a nozzle for 3D printing. Wood, cloth and paper cannot be 3D printed using these processes.
PET and PETG filaments are known for their ease of printability, smooth surface finish, and water resistance.
Polylactic acid (PLA) is currently the most popular filament material used in FDM 3D printing. PLA is supplied in different blends and grades. Standard filaments tend to be the cheapest. Special filaments like silk PLA or color-changing PLA are more expensive.
3D printed steel parts can be as strong or stronger than steel parts made with traditional manufacturing. This depends on a number of variables including your choice of 3D printing method (there are 10), your end use, the type of steel, post-processing, and part shape.
3D-printed metal components are strong if not stronger than those manufactured by traditional means, however their strength varies depending on what the manufacturers requirements are.
What is the best 3D filament for strength?
Polycarbonate. According to multiple manufacturers and reviewers, polycarbonate (PC) is considered the strongest consumer filament out there. PC can yield extremely high-strength parts when printed correctly with an all-metal hot end and an enclosure.
Resin 3D printing, on the other hand, uses a liquid resin material that is cured by UV light to create objects. While filament printing is quicker and produces prints with higher tensile strength, resin printing typically takes longer but produces higher quality, detailed prints with smoother finishes.
You can also use PETG for PLA and just PLA for PETG. PETG and PLA are printed at similar temperatures, but they can't combine and so they are very good as a release material.
Tensile Strength
This determines how much load and stress a part can withstand when being stretched or pulled. PLA+ has an average tensile strength between 45–60 MPa. However, PETG is notably higher with values in the 55–70 MPa range.
PLA has a slightly higher tensile strength than PETG. However, it is more brittle than PETG, making it less resistant to impact or sudden forces. In simple terms, PLA printed parts may require greater forces to break, but when they do eventually break they can shatter into many pieces and potentially cause danger.
