How To Succeed When 3D Printing With Nylon

Everybody with a 3D printer is accustomed to PLA and ABS.

Should you’ve 3D printed with PLA, you in all probability know that whereas it’s pretty sturdy, it’s additionally very brittle. You possibly can’t depart components out within the solar or wherever that the temperature will get above 100°F.

Should you’ve 3D printed with ABS, you realize it’s way more sturdy than PLA, however 3D printed ABS components don’t have the power of injection molded components, and sometimes aren’t sturdy sufficient for purposeful components.

Enter Nylon.

Nylon filament is an extremely sturdy, sturdy and versatile 3D printing materials. Versatile when skinny, however with very excessive inter-layer adhesion, nylon lends itself effectively to issues like residing hinges and different purposeful components. Its low friction coefficient and excessive melting temperature make it a wonderful selection for quite a lot of on a regular basis gadgets resembling 3D printed instruments, gears, RC automobiles and extra.

Not All HotEnds Are Created Equal 

Most 3D printers come normal with hotends that use PEEK and PTFE. Each PEEK and PTFE start to breakdown above 240°C and can burn and emit noxious fumes. When efficiently printing with nylon filament, you may desire a hotend that reaches temperatures of no less than 250°C. Should you aren’t certain in case your scorching finish is setup for 3D printing nylon, ship us an electronic mail or verify together with your printer producer and we are able to let you realize.

Most 3D printers can simply be upgraded with an all-metal scorching finish in an effort to print at temperatures above 240°C (extrusion temperature). We use the E3D V6 All Steel HotEnd on our machines as a result of all-metal design that permits temperatures to securely attain as much as 300°C. They’re wonderful scorching ends that we extremely advocate. Earlier than changing your present printer’s hotend, make sure that to print the proper mount to connect the E3D V6 hotend to your 3D printer.

E3D V6 All Metal HotEnd is the go-to for Nylon 3D printing. You can find them pre-installed on many printers, including our own Pulse 3D Printers.

Mattress Floor Issues: Garolite, Glass and PVA Glue

Like with another kind of filament, the mattress floor you select to print nylon on could be the make or break between warping and profitable 3D printing. For nylon, garolite sheets and glass plates are two construct surfaces we have seen produce probably the most constant profitable outcomes. With the addition of a PVA glue stick, each surfaces present the mattress adhesion essential to bind prints to the construct floor for a clean 3D printing expertise.

Our private favourite floor to make use of with nylon filament is LayerLock Garolite Construct Floor. Made out of fiberglass linen material laminated with epoxy resin, this floor has excessive stability over temperature so it simply withstands the 60°C really helpful for profitable nylon mattress adhesion on a heated mattress. One other perk of utilizing a garolite floor is its sturdy adhesion high quality that lasts for hundreds of prints with sandpaper. Utilizing a sheet of 220 grit sandpaper, calmly sand down the highest of the garolite to take away any blemishes and reveal a extra textured, even floor. This permits nylon to realize a greater grip on the mattress for a profitable flat first layer, resulting in a profitable nylon 3D print general for years to come back.

LayerLock Garolite Build Surface is designed to succeed with nylon, nylon-based filaments like NylonX, and other 3D printing materials.

LayerLock Garolite Construct Floor is designed to succeed with nylon, nylon-based filaments like NylonX, and different 3D printing supplies.

We belief within the success of garolite a lot that we provide it because the inventory mattress floor for our Pulse XE, the 3D printer designed to succeed with 3D printing nylon and nylon-based filaments (on high of ordinary filaments). For optimum success, PVA glue and sandpaper are additionally included with LayerLock Garolite Construct Surfaces for added adhesion and minimal upkeep for longevity. To be taught extra about printing on garolite, try our “How To: 3D Print Nylon on Garolite Print Beds” article.

Nylon Filament Should Be Dried Earlier than Printing

Nylon filament is extremely hygroscopic, that means it readily absorbs water from the air. Nylon can take in greater than 10% of its weight in water in lower than 24 hours which is why it’s best to not depart hygroscopic filaments sitting out within the open.  While you 3D print with nylon filament that isn’t dry, the water within the filament explodes inflicting air bubbles throughout printing that forestalls good layer adhesion, significantly weakens the half and ruins the floor end. Little question about it; profitable 3D printing with nylon and nylon-based supplies require dry filament.

Dry nylon, alternatively, prints buttery clean and has a shiny end.

Desiccant helps hold filaments dry, however packets of desiccant are nowhere close to sufficient to truly extract the moisture out of your 3D printing supplies. MatterHackers’ most well-liked software for drying Nylon is the PrintDry system.  Simply place the spools within the PrintDry chamber, set the system to 75c, and depart to dry for 8-12 hours.  

One other strategy to dry nylon filament is by inserting it in an oven at 160°F – 180°F for six to eight hours. Needless to say most all convection and family ovens don’t regulate their temperature effectively at these decrease temperatures and might simply warp your spool or soften the plastic inflicting it to deform and even adhere the filament stands collectively.

After drying, both instantly print with it in a room that is not chilly or drafty or retailer it in an hermetic container with desiccant to make use of for later. If utilizing a system just like the PrintDry, you may depart the spool within the unit and print immediately from it, retaining moisture at bay whereas on these lengthy prints.

Whereas kitchen ovens are able to drying filament, we extremely advocate utilizing a PrintDry PRO Filament Drying System as a substitute. PrintDry is a secure, desktop-friendly machine engineered particularly for eradicating moisture from filaments. With its compact, transportable design, you may merely place the PrintDry PRO subsequent to your 3D printer and feed dry filament into it whereas it is printing. In case you are unable to feed the filament within the PrintDry PRO immediately into your printer, this filament drying system nonetheless works very effectively for merely drying filament after which storing it in an air-tight container for later. To get the very best quality prints potential, filament drying methods just like the PrintDry are a 3D printing accent we extremely advocate for constant success.

Nylon Can Warp

We have discovered 3D printing nylon can warp about as a lot as ABS.

When printing on glass or garolite, a heated mattress is required with nylon filament. A PVA based mostly glue stick utilized to the mattress is one of the best methodology of mattress adhesion. Elmer’s or Scotch everlasting glue sticks are cheap and simply discovered at an affordable value.

We have discovered {that a} mattress heated to 75°C with a skinny layer of glue utilized in a cross-hatch sample works finest for glass plates.

When printing on a garolite floor, a construct plate is required with nylon filament. Whether or not it is immediately on a heated mattress, a sheet of glass, PEI glass or a FlexPlate System, we advocate the garolite sheet be connected to some type of construct plate that is ready to switch warmth to this construct floor. Like printing on glass, a PVA based mostly glue stick utilized to the mattress could be useful with mattress adhesion for garolite construct surfaces. We advocate Elmer’s glue sticks for this floor. If extra adhesion is required, use 220g sandpaper to calmly sand all throughout the garolite for a textured, even floor that the print can seize onto.

For mattress temperature, we advocate wherever between 55°C – 65°C relying on what kind of brand name and nylon or nylon-based filament you are printing with. If it is NylonX, we advocate 60°C. If it is NylonG, we advocate 65°C.

Don’t use layer cooling followers and keep away from drafty or cool rooms for finest outcomes. If you cannot keep away from inserting your printer in drafty or chilly rooms, think about both make shifting your personal printer enclosure or buying one of many 3D printer enclosure kits offered right here.
