Buying Guide for the Best Cheap 3 D Printers
Choosing the right 3D printer can be a bit overwhelming, especially if you're new to the world of 3D printing. The key is to understand what features are most important for your needs and how to evaluate them. Here are some key specifications to consider when selecting a 3D printer, along with explanations to help you make an informed decision.Print VolumePrint volume refers to the maximum size of the object that the 3D printer can produce. This is important because it determines the scale of your projects. Print volumes are usually measured in cubic inches or millimeters. Small print volumes (e.g., 100x100x100 mm) are suitable for hobbyists and small projects, while larger volumes (e.g., 300x300x300 mm) are better for more ambitious creations. Consider what you plan to print and choose a printer with a volume that matches your needs.
Print ResolutionPrint resolution indicates the level of detail a 3D printer can achieve, measured in microns. Lower micron values mean higher resolution and finer details. For example, a resolution of 100 microns is standard for most consumer 3D printers and is sufficient for general use. If you need highly detailed prints, look for a printer with a resolution of 50 microns or lower. Think about the level of detail required for your projects to determine the appropriate resolution.
Print SpeedPrint speed measures how quickly a 3D printer can produce an object, typically in millimeters per second (mm/s). Faster print speeds can save time, but they may also reduce print quality. Entry-level printers often have speeds around 40-60 mm/s, while more advanced models can reach 150 mm/s or higher. If you need to produce prints quickly, opt for a higher speed, but if quality is more important, a slower speed may be preferable.
Filament CompatibilityFilament compatibility refers to the types of materials a 3D printer can use. Common filaments include PLA, ABS, and PETG, each with its own properties. PLA is easy to use and environmentally friendly, making it ideal for beginners. ABS is more durable and heat-resistant but requires a heated bed. PETG combines the ease of PLA with the strength of ABS. Consider what materials you want to work with and ensure the printer supports them.
Bed LevelingBed leveling is the process of ensuring the print bed is perfectly flat and at the correct distance from the nozzle. This is crucial for print quality and adhesion. Manual leveling requires you to adjust the bed yourself, which can be time-consuming. Automatic leveling uses sensors to adjust the bed, making the process easier and more accurate. If you prefer convenience and precision, look for a printer with automatic bed leveling.
Connectivity OptionsConnectivity options determine how you can send print jobs to the 3D printer. Common options include USB, SD card, and Wi-Fi. USB and SD card are straightforward and reliable, while Wi-Fi allows for wireless printing and remote monitoring. If you value convenience and the ability to manage prints from a distance, choose a printer with Wi-Fi capabilities. Otherwise, USB or SD card options are sufficient for most users.
Build QualityBuild quality refers to the overall construction and durability of the 3D printer. A well-built printer will have a sturdy frame, high-quality components, and reliable performance. Metal frames are generally more durable than plastic ones. Good build quality ensures the printer will last longer and produce consistent results. Consider how often you plan to use the printer and choose one with a build quality that matches your usage.
