How To Succeed When 3D Printing With Nylon


Everybody with a 3D printer is conversant in PLA and ABS.

For those who’ve 3D printed with PLA, you in all probability know that whereas it’s pretty robust, it’s additionally very brittle. You possibly can’t depart elements out within the solar or anyplace that the temperature will get above 100°F.

For those who’ve 3D printed with ABS, you already know it’s rather more sturdy than PLA, however 3D printed ABS elements don’t have the energy of injection molded elements, and sometimes aren’t robust sufficient for purposeful elements.

Enter Nylon.

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

Try our suggestions under on the way to efficiently 3D print with nylon filament.

From achieving excellent bed adhesion to proper filament storage, this guide prepares you with the knowledge and tools you will need to succeed when printing with nylon.

Not All HotEnds Are Created Equal 

Most 3D printers come customary 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 will need a hotend that reaches temperatures of not less than 250°C. For those who aren’t positive in case your scorching finish is setup for 3D printing nylon, ship us an e-mail or examine along with your printer producer and we will let you already know.

Most 3D printers can simply be upgraded with an all-metal scorching finish to be able to print at temperatures above 240°C (extrusion temperature). We use the E3D V6 All Metallic HotEnd on our machines as a result of all-metal design that enables temperatures to soundly attain as much as 300°C. They’re wonderful scorching ends that we extremely suggest. 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 every other sort 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 easy 3D printing expertise.

Our private favourite floor to make use of with nylon filament is LayerLock Garolite Construct Floor. Made out of fiberglass linen fabric laminated with epoxy resin, this floor has excessive stability over temperature so it simply withstands the 60°C really useful for profitable nylon mattress adhesion on a heated mattress. One other perk of utilizing a garolite floor is its robust adhesion high quality that lasts for 1000’s 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 total 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.

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.  If you 3D print with nylon filament that isn’t dry, the water within the filament explodes inflicting air bubbles throughout printing that stops good layer adhesion, enormously weakens the half and ruins the floor end. Little doubt about it; profitable 3D printing with nylon and nylon-based supplies require dry filament.

Dry nylon, alternatively, prints buttery easy 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 popular 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 putting it in an oven at 160°F – 180°F for six to eight hours. Remember that most all convection and family ovens don’t regulate their temperature properly 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 suggest utilizing a PrintDry PRO Filament Drying System as an alternative. 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 properly for merely drying filament after which storing it in an air-tight container for later. To get the highest quality prints potential, filament drying programs just like the PrintDry are a 3D printing accent we extremely suggest 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 inexpensive worth.

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 suggest the garolite sheet be connected to some sort 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 suggest 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 suggest anyplace between 55°C – 65°C relying on what sort of name and nylon or nylon-based filament you are printing with. If it is NylonX, we suggest 60°C. If it is NylonG, we suggest 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 putting 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 bought right here.
