Testing 3D printers involves examining various factors such as hardware quality, ease of setup, bundled software, appearance and accuracy of prints, repairability, company and community support. Different types of 3D printers utilize different materials and printing processes, requiring unique methodologies for testing. For example, SLA 3D printers use resin and light to print, while FDM printers melt plastic onto a plate. A standard test print, like the CNET logo, is used to assess how well a printer bridges gaps, creates accurate shapes, and handles overhangs. Speed is determined by slicing the model with the standard slicer and comparing the real-world print duration to the estimated completion time on the slicer.
Another important aspect of testing involves checking the build plate’s heating capacity using an InfiRay thermal imaging camera. The build plate is set to the most common temperature of 60 degrees Celsius, and its temperature is measured in multiple locations to determine how accurately it reaches the advertised temperature. When testing resin printers, a standard test involving printing a small resin model resembling a tiny town is conducted to assess accuracy, handling of small parts, and UV exposure at different points of the model. Additional anecdotal test prints with various 3D models are used to evaluate longevity and performance with different shapes.
In addition to technical evaluations, the testing process also involves researching the company’s customer support responsiveness, availability of replacement parts, and ease of installation. For printers that come partially assembled as kits, the assembly process’s complexity, duration, and clarity of instructions are assessed. By considering these factors, testers can provide comprehensive evaluations of 3D printers to help consumers make informed purchasing decisions.
Advanced tools and technologies, such as thermal imaging cameras and specific test prints, are used to gather accurate data on the performance and capabilities of 3D printers. With each printer using different materials and processes, testers must adapt their methodology to suit the specific requirements of SLA and FDM printers. By conducting a range of tests, including speed measurements, print accuracy evaluations, and company support inquiries, testers can provide a well-rounded assessment of a printer’s quality and suitability for various applications.
Overall, the testing process for 3D printers is thorough and detailed, encompassing a wide range of criteria to accurately evaluate each printer’s performance. From testing heating capabilities and print accuracy to assessing company support and assembly ease, testers strive to provide consumers with comprehensive insights into the strengths and weaknesses of different 3D printers. By utilizing specialized tools and conducting standardized test prints, testers can gather reliable data to help consumers make informed decisions when selecting a 3D printer.
