Testing 3D printers involves assessing hardware quality, ease of setup, bundled software, appearance and accuracy of prints, repairability, and company and community support. Different types of 3D printers, such as SLA and FDM printers, utilize different materials and processes to create models. Key test prints, like the CNET logo, are used to evaluate how well a printer bridges gaps, creates shapes, and handles overhangs. Speed is tested by comparing the real-world print duration with the slicer’s estimated completion time and determining the speed in millimeters per second.
For FDM printers, the build plate’s heating capabilities are tested using an InfiRay thermal imaging camera. The build plate is set to 60 degrees Celsius, a common temperature, and the temperature is measured in six locations to determine how close it gets to the advertised temperature. Resin printers are assessed using the Ameralabs standard test, which involves printing a small resin model to evaluate accuracy, small part handling, and UV exposure. Various other test prints are also used to assess longevity and performance with different shapes. Company responsiveness to support queries and ease of ordering replacement parts are researched to evaluate customer service.
In addition to the technical aspects of testing, the assembly process for kits is also evaluated. The difficulty and length of assembly, as well as the clarity of instructions, are factors that contribute to the overall assessment of the printer. Testing different 3D models on each printer helps determine how well the machine copes with various shapes and sizes. Researching the company’s reputation and customer support helps gauge the overall reliability and user-friendliness of the printer. Overall, a comprehensive approach is taken to thoroughly test 3D printers and provide accurate assessments for potential buyers.
The testing process for 3D printers involves a combination of technical assessments and practical evaluations. By analyzing hardware quality, setup ease, software functionality, print accuracy, repairability, and customer support, a holistic view of each printer is obtained. Speed tests, heating assessments, and resin printing criteria aid in determining the overall performance and capabilities of the printer. The use of standard test prints and various models helps evaluate the printer’s handling of different shapes and sizes. Customer service responsiveness, replacement part availability, and assembly process clarity are also considered in the testing process.
Utilizing tools like thermal imaging cameras and print analysis software helps in obtaining accurate and objective test results. By comparing real-world print durations with slicer estimates, the speed and efficiency of the printer can be determined. Researching company reputations and customer feedback provides valuable insights into the overall user experience with the printer. The testing criteria cover a wide range of factors to ensure a comprehensive evaluation of each 3D printer, helping potential buyers make informed decisions. Overall, the testing process is designed to provide detailed and reliable information about the performance and usability of different 3D printers.
