Testing 3D printers is an in-depth course of. Printers usually do not use the identical supplies, and even the identical course of to create fashions. I check SLA, 3D printers that use resin and lightweight to print, and FDM, printers that soften plastic onto a plate. Every has a novel methodology. Core qualifiers I have a look at embrace:
- {Hardware} high quality.
- Ease of setup.
- Bundled software program.
- Look and accuracy of prints.
- Repairability.
- Firm and neighborhood help.
A key check print, representing the (now previous) CNET brand, is used to evaluate how a printer bridges gaps, creates correct shapes and offers with overhangs. It even has little towers to assist measure how properly the 3D printer offers with temperature ranges.
When testing pace we slice the mannequin utilizing the usual slicer the machine is shipped with on its normal settings then examine the real-world period of the print to the assertion completion time on the slicer. 3D printers usually use completely different slicers, and people slicers can differ wildly on what they imagine the completion time to be.
We then use PrusaSlicer to find out how a lot materials the print ought to use and divide that quantity by the real-world time it took to print to provide us a extra correct quantity for the pace in millimeters per second (mm/s) the printer can run at.
Each construct plate is meant to warmth as much as a sure temperature so we use the InfiRay thermal imaging digicam for Android to test how properly they do. We set the construct plate to 60 levels Celsius — essentially the most used temperature for construct plates — waited 5 minutes for the temperature to stabilize, then measured it in six separate areas. We then took the typical temperature to see how shut the 3D printer acquired to the marketed temperature.
Testing resin requires completely different standards so I exploit the AmeraLabs normal check — printing out a small resin mannequin that appears like a tiny city. This helps decide how correct the printer is, the way it offers with small components and the way properly the UV publicity works at completely different factors within the mannequin.
Many different anecdotal check prints, utilizing completely different 3D fashions, are additionally run on every printer to check the longevity of the components and the way properly the machine copes with numerous shapes.
For the opposite standards, I analysis the corporate to see how properly it responds to help queries from prospects and the way straightforward it’s to order substitute components and set up them your self. Kits (printers that come solely semiassembled) are judged by how lengthy and tough the meeting course of is and the way clear the directions are.
