However, even these systems can struggle to control the materials proneness to warping. Although most desktop printers can process nylon filament, the high-strength material has drawbacks. He is a contributing editor at Aniwaa and a senior writer at 3dpbm. Markforged state that their carbon fiber filament has the highest strength-to-weight ratio, where in their flexural strength three-point bending test, illustrated that it is 8x stronger than ABS and 20% stronger than the yield strength of aluminum. After being the stiffest 3D printing material it is also known as the most environmentally friendly material to be used in 3D printers. They demand much higher temperatures (nozzle, bed, and enclosure) than regular materials, are more expensive, and sometimes require annealing to maximize their mechanical performance.[2]. The strength and stiffness of thermoplastics can be increased by mixing them with reinforcing additives, creating what is called a composite filament. On top of its incredible strength, PC also has transparent and lightweight qualities which make it a serious contender for 3D printing materials. Best PLA Filament &, Best Filament to Buy on Amazon for 3D Printing, Which 3D Printing Filament is Most Flexible? Standard build surfaces like blue tape and glue stick have adhesives that break down at the high temperatures required to print Polycarbonate. Tensile strength of commercial polymer materials for fused filament fabrication 3D printing. ABS comes in the list of the strongest filaments because it is a hard thermoplastic material that can resist impact gracefully. It is considered as a standard filament material that is widely being used because it can print clearly at a very low temperature without requiring a high heated bed. You want to make sure the bridging fan speed stays at a low value, otherwise it has a tendency to cause warping and separation due to the rapid temperature change. ABS is a perfect choice if you are going to print things that will have the stress of will include high functionality. Popular nylon filaments include MatterHackers Pro Series Nylon, Ultimaker Nylon, and ColorFabb PA. Another key indicator of strength is impact strength. You can print this on an Ender 3 comfortably, but an all-metal hotend is recommended (not required). Nylon is an excellent and strong material that is used in most of the 3D printers. What is the Weakest 3D Printing Filament? Finally, its clarity and ability to transmit light means that polycarbonate printing material will produce beautiful printed objects when used correctly. Compared to PC, it is slightly more flexible, which may be desirable for certain functional parts. These characteristics can include printability, durability, chemical resistance, temperature resistance, and flexibility, to name just a few. There a number of good 3D printer enclosures we recommend below: Below are links to some of the Polycarbonate filaments we recommend for 3D printing.

Polycarbonate that has been exposed to humidity will exhibit problems when being extruded, mainly bubbles and inconsistent flow that will tend to ruin your design. If your extruder has a problem with temperatures this high, dont worry. ABS has more flexible strength since PLA is brittle and doesnt have as much give. It is also used in electrical and phone casings, bike and motorbike helmets, and other strong parts like scuba diving masks and even riot shields. Low-cost piezoelectric films produce voltage, could be used for flexible electronic components and more. Similar to the point above, bridging segments can also be affected by the high printing temperatures of Polycarbonate. Their carbon fiber has a flexural strength of 540 MPA, which is 6 times higher than their nylon-based onyx filament and its also 16 times stiffer than their onyx filament. Although not as robust as PC, nylon filament is marginally easier to print, requiring an extruder temperature of around 250 C and a heated bed set to around 80 C. Heated Bed Required As it is mentioned above that simple nylon or some PLA filaments are considered as the weakest 3D printing filaments in the 3D industry. We recommend using a first layer height of 100-150%, a first layer width of 12-150%, and a first layer speed of 15-30%. However, at the end of the day, slow and steady wins this particular race. PETG can also withstand higher temperatures than PLA, but you want to make sure your 3D printer has the correct capabilities to reach the necessary temperatures to print it. Yet, as weve been discussing, its the category of overall strength that sets polycarbonate 3D filament apart from other thermoplastics. The atoms are in a crystalline structure that provides high strength which makes it an ideal choice for industries like automotive. One user actually tested how much carbon fiber was in the PRILINE Carbon Fiber Polycarbonate Filament and they estimated it was around 5-10% carbon fiber volume to plastic. PEEK filament, for example, can have a tensile strength as high as 100 MPa, notably higher than PC filament and significantly higher than ABS filament. Most available Polycarbonate filaments contain additives that allow the filament to be printed at lower temperatures, so make sure to consult the guidelines for your specific brand of plastic. Extruder temperatures of at least 260 C are required, with some formulations needing more than 300 C, which is beyond the capabilities of consumer-level desktop 3D printers. Polycarbonate or PC is an extremely strong, lightweight and transparent thermoplastic. The all-famous Legos are made from ABS, and those things are indestructible! Make sure you print in an area with good ventilation, and try not to be in the same room while printing. It is an ideal choice for printing durable parts. Most desktop 3D printers can print TPU and other varieties of thermoplastic elastomer (TPE), with a hot end temperature of around 230 C required. This filament is widely used in printing processes such as engineering purposes, technical printings, etc. The durability and rigidity of PC outweighs other printing materials easily. Below are a few suggestions to help you get started. PC has a very high impact strength, far greater than glass and more than ten times that of an acrylic material likePMMA. If your 3D printer doesnt come with an enclosure, you can buy one, or build one yourself. It has a Rockwell hardness of R 121, making it harder than PMMA, ABS and PLA. All of the various strength-related attributes are important when it comes to choosing and buying 3D printer filament. PC has amazing impact strength, higher than that of glass and several times higher than acrylic materials. It also transmits light better than most types of glass. PC filament is also bendable and machine bendable at room temperature with this flexibility allowing it to withstand high tensile forces that break or shatter filaments like ABS. However, materials can have a high impact strength and a low tensile strength, and vice versa. Fix retraction settings: This will minimize oozing. You will need an all-metal hot end for consistent Polycarbonate 3D printing, as PEEK or other material hot ends will struggle to maintain these high temperatures consistently. The strongest 3D printer filament you can buy is polycarbonate filament. PC has a specific gravity of 1.18 g/cm. When it comes to the strongest filaments, polycarbonate filament will always be seen at the top of the list as described above. Note, however, that FDM carbon fiber filaments have limits on their strength, because the chopped fibers mixed into the material are randomly oriented. High print temperatures mean that extruded filament will tend to droop if it is unsupported. One of the tough competitors is ABS filament but you will be amazed to know that Polycarbonate filament can withstand 40C more than ABS, making it a very strong filament. This allows the printer to make faster movements, which means less time for oozing. Id thought it would be a lot pricer but it actually isnt too bad! Simplify3D also includes a useful option called Coasting, which will automatically reduce the pressure in the nozzle right before the end of a segment to avoid oozing when moving to the next segment. Used to indicate the ultimate strength of a material or part, tensile strength can be defined as the ability to resist breakage when under tension, i.e. Good 3D printing materials tend to offer a mix of desirable characteristics. This brings us to our second How to 3D print with polycarbonate tip. These additions can make the nylon filaments more strong and resistant. Its mechanical structure is unlike many others, where strength tests have shown the excellent resilience and strength of this filament. Carbon fiber is a thin filament composed of fiber that contains carbon atoms. In a nutshell, Polycarbonate filaments is the king of the 3D printing filament when it comes to strength.

Simplify3D added many new bridging features in Version 4.0, so these can be used to customize exactly how the bridges are printed for the best results. If you expect your 3D printer part to bend or twist, you would rather be using ABS over PLA. This density makes it comparable to PMMA and PLA and about one-fifth denser than ABS. All-metal hotend required. It just needs to keep heat in effectively to reduce warping and layer splitting. At the low-cost consumer level, the strongest 3D printer filaments in terms of tensile strength include polycarbonate (PC), polyethylene terephthalate glycol-modified (PETG), and polylactic acid (PLA). If the parts need to withstand sudden impact, then materials with a high impact strength or toughness should be prioritized. The more water there is in the air, the more moisture the polycarbonate will absorb. If you want a filament which meets in the middle of the two, you want to look towards using PETG, which is easy to print like PLA, but has a little less strength than ABS. First of all, polycarbonate is heat resistant up to 116C. In professional and industrial settings, many FDM users are now turning to high-performance materials like PAEK (PEEK and PEKK) and PEI (ULTEM) for the production of end-use parts, especially in demanding industries like automotive and aerospace. It is used for bullet-proof glass, riot gear, phone & computer cases, scuba masks and much more. Weak materials include thermoplastic polyurethane (TPU) and acrylonitrile butadiene styrene (ABS). PETG has more natural flex than PLA and should keep its shape longer. [1] Tanikella NG, Wittbrodt B, Pearce JM. Compare this to the tensile break strength of PMMA (1.8% 7.2%), PLA (1% 12%) and ABS (4.6% to 27%). Its far tougher than filaments like ABS or PLA, and stands up very well to general wear and tear over time. It is durable with impact and high shatter resistance. Using a larger 3D printer nozzle will improve layer adhesion if this is something you are struggling with, as the larger surface area improves the bonds between layers. You can purchase 2KG of carbon fiber PETG for around $170 from 3DFilaPrint which is very premium for 3D printer material, but a great price for high quality filament. The ability to shake off high temperatures is both a blessing and a curse PC is a notoriously difficult 3D printer filament to print but well explain some best practices in this Polycarbonate 3D printing guide. Advanced composite printing technologies, such as those developed by Markforged and Desktop Metal, are able to print continuous fibers, resulting in much stronger parts.[3].
