Buyer Guide 3D Printers

 A 3D printer is a machine that allows you to create three-dimensional objects from a digital file or from a 3D model.

• Price. The price ranges from $300 for an entry-level printer to $5,000 for an industrial printer.
• Print Speed. The print speed is the amount of time it takes to print a 3D object. The print speed varies with the printer model, but the average is 0.2 to 0.4 seconds per layer.
• Resolution. The resolution is the number of points per inch (PPI). The higher the resolution, the more detailed the 3D object will be. The higher the resolution, the more detailed the 3D object will be.
• Nozzle size. The nozzle size indicates the size of the nozzle used. The nozzle size on entry-level printers is 0.4 mm and goes to 0.3 mm on professional printers.
• Materials. There are many types of 3D prints. The most common is PLA, which is approved by the ABS standards.
• Filament. The filament is the material that goes into the nozzle of the printer. The filament comes in various colors and is typically sold in 1.75-gallon spools.

How to choose 3D Printers

 3D printing is a fairly new technology, and it can be difficult to sort through all of the different products available. Before you invest in a new printer, it’s important to consider which 3D printer model will best suit your printing needs.

• Are you going to print mostly small items, or bigger, highly detailed parts? If you are only going to be printing small, highly detailed items, you may want to invest in a printer that can produce smaller parts.
• Do you want to print in plastic or metal? Some printers can print in plastic, while others can print in metal. Also, some printers can print both.
• Do you need to print in full color? If you are looking to create full-color prints, you will likely need a 3D printer that can print in full color. Most 3D printers can print in somewhere between 1 and 6 colors.
• Do you need to print in high resolution? If you are printing in plastic, you may need to invest in a printer with a high-resolution printhead.
• Do you need to print in biodegradable materials? More and more 3D printers are capable of producing prints in biodegradable materials like PLA.
• Do you need to print using 3D models? Some 3D printers can scan an object and turn it into a 3D model that the printer can print.

How to maintain 3D Printers

3D printing is a remarkable way to create complex, functional objects. However, 3D printing is also incredibly time-consuming, complicated, and expensive.

Because of this, many 3D printers require regular maintenance. For instance, most 3D printers have a nozzle, which can get clogged with debris over time.

These clogs can slow down your prints, cause jams and errors, and ruin the quality of your 3D creations.

There are countless tutorials and guides on how to unclog a 3D printer’s nozzle. However, many of these guides require expensive replacement parts or professional equipment.

Luckily, there are several ways to clean your 3D printer’s nozzle without purchasing expensive replacement parts. Some of the most common ways to clean a 3D printer’s nozzle are:

• Cleaning the nozzle with alcohol.
• Cleaning the nozzle with dish soap.
• Installing a UV lamp.
• Cleaning the nozzle with a toothbrush.
• Using a rotating brush.
• Using compressed air to blow away debris.
