Bring your 3D printer to the next level. Here are the essential 3D printer parts & accessories you can find at Amazon.

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.

Essential 3D Printer Parts & Accessories 3D Print Removal Tool

Image of Essential 3D Printer Parts & Accessories: 3D Print Removal Tool

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.

Essential 3D Printer Parts & Accessories Signstek Tempered Borosilicate Glass Plate

Image of Essential 3D Printer Parts & Accessories: Signstek Tempered Borosilicate Glass Plate

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.

Essential 3D Printer Parts & Accessories XTC-3D High Performance 3D Print Coating

Image of Essential 3D Printer Parts & Accessories: XTC-3D High Performance 3D Print Coating

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.

Image of Essential 3D Printer Parts & Accessories: White PTFE Bowden Tube - 1

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 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.
