Things to consider before buying a 3d printer: Build Volume: The build volume refers to the maximum size of objects that can be printed. If wanted to print large objects, then need a printer with a larger build volume. Print speed: Print speed is an important factor to consider if wanted to print large quantities of items. Support and warranty: Look for a printer with a good warranty and reliable customer support. Cost: It's important to set a budget and choose a printer that fits price range. Ease of use: Some 3D printers require a certain level of technical knowledge to operate. For beginner, it is important to choose a printer that is easy to use and comes with clear instructions. Maintenance cost: You will definitely not want to invest your money in something that is high on maintenance. So, make sure that you check the price of servicing, the cost of spare parts and more before you buy a 3D printer online. Print resolution: The 3D printer that you are buying must match your requirements for printing. So, check the printing resolution and other related features that will assess whether the output produced by the printer is apt for your needs or not. Materials: Some printers only print with their own proprietary materials while others are open to almost any material. You may be able to find more affordable material for the open printers, but cheaper isn’t always the best choice. Bed Leveling : Some printers offer automatic bed leveling, which can simplify the setup process.
Mainly used technologies for 3D printing. Stereolithography (SLA)- Liquid Resin Selective Laser Sintering (SLS)- Powder Fused Deposition Modeling (FDM)-Solid Digital Light Process (DLP) Multi Jet Fusion (MJF) PolyJet Direct Metal Laser Sintering (DMLS) Electron Beam Melting (EBM) FDM 3D Printing Materials MATERIAL FEATURES APPLICATIONS ABS (acrylonitrile butadiene styrene) Tough and durable Heat and impact resistant Requires a heated bed to print Requires ventilation Functional prototypes PLA (polylactic acid) The easiest FDM materials to print Rigid, strong, but brittle Less resistant to heat and chemicals Biodegradable Odorless Concept models Looks-like prototypes PETG (polyethylene terephthalate glycol) Compatible with lower printing temperatures for faster production Humidity and chemical resistant High transparency Can be food safe Waterproof applications Snap-fit components Nylon Strong, durable, and lightweight Tough and partially flexible Heat and impact resistant Very complex to print on FDM Functional prototypes Wear resistant parts TPU (thermoplastic polyurethane) Flexible and stretchable Impact resistant Excellent vibration dampening Flexible prototypes PVA (polyvinyl alcohol) Soluble support material Dissolves in water Support material HIPS (high impact polystyrene) Soluble support material most commonly used with ABS Dissolves in chemical limonene Support material Composites (carbon fiber, kevlar, fiberglass) Rigid, strong, or extremely tough Compatibility limited to some expensive industrial FDM 3D printers Functional prototypes Jigs, fixtures, and tooling
