Best 3D Printers for $100 to $150: A Comprehensive Guide

When it comes to purchasing a 3D printer within the budget of $100 to $150, there are a few options that stand out. While not as diverse as higher-priced ranges, the choice depends heavily on your specific needs and the tasks you intend to perform.

Choosing the Right 3D Printer

Among the options that fit your budget, some popular choices include the Ender 3 and the Elegoo Mars. With a reasonably large print bed, the Ender 3 is a versatile choice. A refurbished version of the Elegoo Mars also offers a slightly higher definition with a smaller print bed for under $200. The choice between the two depends on your specific requirements and the tasks you plan to perform. Each printer has its strengths and weaknesses, which should be carefully considered before making a decision.

Low-End Technology: FDM vs. SLA

For the price range of $100 to $150, you likely won't find many options outside of Fused Deposition Modeling (FDM) technology. FDM is the most common low-end type of 3D printing that involves melting a filament and depositing it through a computer-controlled nozzle. FDM is also the type of 3D printing used in the Ender 3 and Anet A8.

Alternatively, if you're working with very small pieces, you might consider an SLA (Stereolithography) printer. SLA printers use lasers to harden resin and create very precise and detailed models. However, the technology and print materials for SLA are typically more expensive and beyond this price range. Therefore, for most users, FDM is the best fit unless you have specific needs for extremely detailed models.

The Anet A8: An Affordable Choice

When I purchased my Anet A8 on Amazon for $148 (with delivery) during a Vipon discount, I had mixed feelings. While it was a kit that took a considerable amount of time to assemble (a day or more), it is a cost-effective option for its parts and assembly level. However, it lacks some safety features due to its minimization of costs, which is a potential risk for inexperienced users.

Important Considerations and Recommendations

Firstly, it's important to note that the Anet A8 is a kit printer and can be challenging to assemble. Secondly, because the firmware lacks important safety features, it poses a risk to inexperienced users. In fact, there have been reports of the printer starting fires, leading to its infamous status as a fire starter.

Despite these drawbacks, the Anet A8 performs surprisingly well once assembled and properly calibrated. The machine is user-upgradeable, allowing you to flash updated software, replace the power supply, and MOSFETs. Importantly, the most crucial upgrade is free and relatively simple to perform.

After purchasing, it's essential to document and address the flaws of the printer. By the time my printer arrived, it had already been well-documented, and I was prepared to reflash the software and order upgraded MOSFETs and a power supply. Three years later, the printer has seen considerable use, and my house remains safe and sound, with no smoke alarms triggered.

To ensure the longevity and safety of your printer, it's crucial to select a model with an active user community. Researching the idiosyncrasies of popular models before making a purchase can also provide valuable insights and help you avoid common pitfalls.

Ultimately, when looking for a 3D printer in the $100 to $150 range, the Ender 3 and Elegoo Mars are strong contenders. For those willing to build and modify the machine, the Anet A8 can provide a satisfying experience, though with significant considerations regarding safety and reliability.
