3D printers are complex machines. Most of their components like the frame, pulleys, print bed, and metal rods don’t usually leave too much room for customization or improvements. Other 3D printer parts, on the other hand, like the extruder, hotend, print-bed and nozzle are easy to customize, adjust and calibrate. A lot can also be done in the way of post-processing 3D printed objects.
This article covers the basic items needed to upgrade, extend, and accessorize your 3D printer.
This list of 3D printer parts and accessories has been put together using select articles, found in the 3D Printer Parts & Accessories category at Amazon, and is strongly based on the best selling products in that category over the last 30 days.
A 3D print removal tool is an absolute must have for anyone who 3D prints. Removal tools help with the removal of 3D prints from the build plate after printing. They are also suitable for scraping off little bits of filament. Through the nature of the tool, force can be applied to the 3D printed object in a number of ways to help remove it without causing too much damage or any damage at all.
Since the Anet A8 has had current load issues concerning the heat bed, it is a good idea to install a MOS tube like this one, as an expansion, to relieve the main board of the full current needed to power the heat bed.

Borosilicate glass is suited for 3D printing applications because it is tempered and can, therefore, withstand high temperatures. This makes it suitable for heated print beds. Glass, in general, is desired for its smooth surface finish. This build plate should be compatible with most machines with similar or corresponding dimensions. To increase the adhesive quality of the build surface, it is common to use a layer of glue from a glue stick or hairspray. It is important to note that hairspray is flammable and should be used with caution, especially when dealing with heated elements like hot ends and heated build plates.
Is your 3D printer’s nozzle blocked? This is an annoying problem that can cause a 3D printer to stop working. One way to fix this issue is to use a tool like one of these drills to carefully clear up the nozzle while it is hot.
This is really quite self-explanatory. Achieve better temperature consistency by insulating the heating block of the extruder.
The manufacturer warns not to use this product at temperatures above or equal to 300°C and strongly advises making sure that the guidelines for this kind of modification are followed. They will vary depending on the 3D printer.
This is a 14 piece bundle containing six 30 mm long 1.75 mm extruder tubes and six 0.4 mm brass nozzles. The components are compatible with MK8 MakerBot Reprap 3D printers. The bundle also includes two nozzle clearing drill bits.
The extruder and print bed of most desktop 3D printers are controlled using this kind of belt. It’s no wonder that this item is among the best selling products in the Parts and Accessories category on Amazon. This belt can either be used in 3D printer builds from scratch, or to replace old belts.
Every maker needs at least one 3D print removal tool. Removing finished prints or even scrap filament and leftover glue from the build plate is that much easier with the proper tools. This set includes a longer and a shorter scraper. Depending on the situation, either tool may be better suited than the other.
You’ve probably heard that ABS can be smoothed with acetone. However, acetone can’t be used to post-process PLA for instance. This epoxy can be used to post-process any kind of 3D printing material including materials like wood fiber infused PLA. Please note that this does not produce the same result that acetone does. Acetone acts subtractively while this epoxy adds a smooth coating on top of the 3D printed object. Follow the instructions to mix the two liquids together and apply the solution with a brush. It will take about 4 hours to cure.
If you’re building a 3D printer from scratch, chances are you’ll want an auto-leveling sensor for your print bed. This will make everyday 3D printing a lot more comfortable.
This is a 14 piece bundle of M6 threaded brass nozzles ranging from 0.2 mm to 1.0 mm. Each nozzle size is contained twice. These should be compatible with any 1.75 mm 3D printer. Don’t use these nozzles with abrasive materials like carbon fiber infused filaments as they will wear out the nozzle rather quickly.
Micro Swiss make high precision machined parts. This is their all metal hotend. The lower heat break is made out of stainless steel which does not conduct heat as well as aluminum, which is used for the cooler part of this hotend. This combination allows for good heat control. This hotend is a good upgrade for the Wanhao i3.
Here is a 6 piece bundle of 0.4 mm brass nozzles suitable for 1.75 mm MK8 extruders. Note that these nozzles are not suitable for abrasive 3D printing materials.
These are linear bearings for 8 m shafts that can be used as replacement parts for Reprap builds or as components for a 3D printer build from scratch. Please note that these bearings are self-lubricating.
This is a 2 m long PTFE Bowden tube that can withstand temperatures of up to 260°C. A Bowden extruder is one that separates the hotend from the feeder. This means that the feeder along with the motor is in a fixed position somewhere on the frame of the 3D printer while the hotend (now much lighter) is where it always is. A PTFE tube is needed to guide the filament to the hotend.
This is exactly the same type of Bowden tube featured directly above. The only difference is that this one is 50 cm shorter at 1.5 m. Once again, don’t let this tube get hotter than 260°C.
Similar to the bundle above, this product includes five 3 cm long extruder tubes for 1.75 mm filament and five 0.4 mm brass nozzles. These are great replacement parts for any compatible 3D printer, especially Reprap models.
This is a 5 piece set of 3D print removal tools. 5 tools should be more than enough to separate 3D prints from the build platform.
This is a 3 pack of square shaped (203 x 203 mm) build surfaces. Place this on top of the build platform of a 3D printer. It will improve first layer adhesion and make it easier to remove finished prints.
This is basically a clone of the E3D V6 All-Metal hotend. That aside, this one is more affordable. It is a Bowden hotend compatible with 1.75 mm filament and comes with a 0.4 mm brass nozzle. The pack comes with a 1 meter long PTFE tube. This hotend is compatible with Reprap 3D printers.
This is a digital temperature controller that can be integrated into any project, even 3D printers. The device can measure temperatures from -50°C to 99°C. As you can see, it is more general purpose than meant for 3D printers. Since it can only measure temperatures up to 99°C, it can only really be used to control the temperature of the heat bed.
Use the included 3M adhesive tape to fasten this build surface sheet to the build platform of a 3D printer. This sheet will improve first layer adhesion problems when using materials like ABS or PLA.
This is a 2 m long PTFE tube for a Bowden setup. Use this to guide the filament from the fixed feeder to the hotend. This package includes fittings for the 1.75 mm Reprap Bowden hotend.
Organize your desk space with this filament mount rack. Either mount it to the wall or to a desk and easily have two spools of filament ready to use. Note that the mounting screws are not included in this package.
