The phrase “high resolution” gets thrown around a lot in 3D printing. But what does it mean to have a “high-resolution 3D printer”?
Unlike photography (expressed picture detail regarding megapixels) and laser printing (dots per inch), 3D printing is much more complicated as there isn’t a single metric to measure the effective resolution.
Other manufacturers will try to sell their printer as ‘high-resolution’ based on these factors.
Layer Height: How thick of a bead of plastic is applied to each layer
Minimum Feature Size / Nozzle Size: How wide a bead of plastic is applied
Neither of these factors translates into the aesthetic appearance and dimensional accuracy of your part (does the part measure up to its dimensions in your CAD drawing?).
Fusion3 believes that two key factors contribute to overall print quality (as a proxy for high-resolution): Precision and Layer Alignment.
Precision is the ability of the print head to dispense each layer of plastic as exactly as designed by the user in his/her CAD software. If the 3D printer cannot get the plastic placed at the right coordinates, your quality will immediately suffer.
Layer Alignment is the 3D printer’s ability to place each layer as exact as possible about the previous layer. If a print doesn’t have the layers aligned properly, let’s say for a cube, then the surface will appear rough and not have the desired dimensional accuracy required by the customer.
The motion control system (F-Series Platform) used in Fusion3’s F400 3D printer provides excellent precision and layer alignment. We use a proprietary variant of “Core XY” drive system with enhancements we’ve developed that can precisely position the print head, dispense materials and repeat each layer with a level of precision that ensures great print quality and excellent dimensional accuracy.
Other manufacturers hide the flaws of their motion control system by reducing layer size and slowing down their 3D printer to improve accuracy. Fusion3’s system not only is accurate and precise but is also faster than most FDM 3D printers on the market. Our system can balance both your effective print quality with time to print to ensure an efficient, productive print system for our business and education customers.
