Other materials used in FFF printing include, but are not limited to, high-impact polystyrene (HIPS) composite filaments made of wood, bronze, and copper UV-luminescent filaments nylon Tritan copolyester polyvinyl alcohol (PVA) polyethylene terephthalate (PETT) polycarbonate conductive PLA and ABS plasticized copolyamide thermoplastic elastomer (PCTPE) and PC-ABS. PLA prints look smooth, but they tend to be on the brittle side. For example, ABS melts at a higher temperature than PLA and is more flexible, but emits fumes when melted that many users find unpleasant, and it requires a heated print bed. The two most common types of filament are acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA). What Are Your Objects Made Of?Īs for the materials you'll use to print with, most affordable 3D printers use the abovementioned FFF technique, in which plastic filament-available in spools-is melted and extruded, then solidifies to form the object. In our reviews, we list printers' build areas in inches in height, width, and depth (HWD). Typical 3D printers have build areas between 6 and 9 inches square, but they can range from a few inches to more than two feet on a side, and a few are actually square. The build area is the size, in three dimensions, of the largest object that can a given printer can produce (at least in theory-it may be somewhat less if the build platform is not exactly level, for example). Make sure that a 3D printer's build area is large enough for the kind of objects that you intend to print with it. (Although they are not strictly 3D printers, we also include 3D pens-whose users apply molten plastic "ink" by drawing freehand or using a stencil-in this roundup.) A few 3D printers use stereolithography-the first 3D printing technique developed-in which ultraviolet (UV) lasers trace a pattern on photosensitive liquid resin, hardening the resin to form the object. It's also called fused deposition modeling (FDM), although that term is trademarked by Stratasys Inc. Most printers in this segment build 3D objects out of successive layers of molten plastic, a technique known as fused filament fabrication (FFF). Individuals wanting to show off the wonders of 3D printing to friends or clients will want a handsome yet reliable machine.įor this guide, we will focus on 3D printers targeted at consumers, hobbyists, schools, product designers, and other professionals such as engineers and architects, rather than high-end industrial printers. Shops involved in short-run manufacturing will like a large build area to print multiple objects at once. Designers and other professionals demand outstanding print quality.
Hobbyists and artists may want special features such as the ability to print objects with more than one color or multiple filament types.
Consumers and schools will want a device that's easy to set up and use, doesn't need much maintenance, and offers reasonably good print quality. The best 3D printer for you depends on how you plan to use it.

Best Hosted Endpoint Protection and Security SoftwareĪctually, not only should you ask what you want to print, but a more fundamental question: Why do you want to print in 3D? Are you a consumer interested in making toys or household items? A trendsetter who enjoys showing the latest gadgetry to your friends? An educator seeking to install a 3D printer in a classroom, library, or community center? A hobbyist or do-it-yourselfer who likes to experiment with new projects and technologies? A designer, engineer, or architect who needs to create prototypes or models of new products, parts, or structures? An artist who sees fabricating 3D objects as a kind of sculpture? Or a manufacturer looking to print plastic items in relatively short runs?.
