How to choose a 3D printer
Three-dimensional printers cover a wide variety of sizes and prices, with some industrial models able to support print shops. Such devices, of course, go beyond the needs or means of most people, and the vast majority of consumer devices are designed to fit on a tabletop. Even these are very important in terms of cost. So, it's worth spending some time tracking down a cheap 3D printer (or at least a worthy 3D printer deal for a more expensive device) that will meet your budget while satisfying your budget needs.
Modern 3D printers use one of two manufacturing technologies: Fused Deposition Modeling (FDM) or Stereolithography (SLA). FDM printers are more popular and use a printing medium known as filament. This filament is heated to its melting point and then extruded through one or more printheads that move along three axes to create an object layer by layer from bottom to top on a heat dissipating build sheet.
FDM printers tend to be the easiest to use, and the filaments they use are also very common and quite affordable, making these cheap 3D printers good for household items and other common projects. Items made with an FDM 3D printer usually look noticeably striped because of this layer-by-layer construction, but filaments and the printers that use them are improving and becoming better able to handle complex tasks to be tackled when this technology is further developed. Most of the cheap 3D printers you can find have this design.
While stereolithography is a decades-old technology, it is less common due to the higher cost of SLA printers and their proprietary resins (there are some cheap 3D printers that use resin, but they tend to be smaller). Instead of using filament as a printing substrate, SLA printers start with a resin liquid that is hardened by UV radiation as it is molded into the desired shape within the pressure chamber. The UV laser is reflected by mirrors to selectively target the resin to be cured. This is also done layer by layer, but in a completely different way than when modeling the enamel deposit.
Resin-based SLA printers can therefore produce smoother, more detailed, and higher-resolution objects than FDM printers. These resin objects also tend to be much more durable. The downside is that SLA 3D printers (and the resins) tend to be more expensive than FDM units, and the proprietary resins are less flexible and messier to use.
