When lower layer thicknesses make little senseĪ lower slice height leads to a higher Z-resolution, nevertheless, it is not always useful. With a lower layer thickness, more layers are applied on top of each other, this circumstance leads to a higher error rate. If, for example, the layer height is halved from 300 μm to 150 μm, then printing takes twice as much time and the costs also increase enormously. On the other hand, the layer height has significant effects on the printing process. The layer thickness (= Z-resolution) can be set on every 3D printer and is sometimes also dependent on the 3D printing process. A lower layer thickness leads to a higher resolution of the object and to smoother surfaces.

Choosing the right layer height is quite comparable to deciding on the resolution of a TV screen. The selected layer height has a direct effect on the print result. Resin: Differences, Pros & Cons The effect of layer height on the printing process But especially with the SLA and FDM processes, the choice of layer thickness is a very important factor.įDM vs. With some printing processes, the layer height has hardly any effect on the result. Of course, there are also 3D printers available that can also create a layer height below 50 μm (= 0.05 mm). For commercially available 3D printers, the layer height is approximately between 0.1 and 0.4 mm. In 3D printing, the object is built up layer by layer. 5.7 What else should be considered for the nozzle diameter?.5.6 Which nozzle diameter is suitable for what?

1.1 The effect of layer height on the printing process.If your work calls for prints with intricate details, look for a printer with an XY resolution that’s backed by measurable data, not just a number. Not every 3D printer’s published resolution holds true, so it’s a good idea to do plenty of research before choosing the one that's right for your project. Considering the printer’s entire ecosystem, a 10-micron difference is nominal.
The minimum feature size can never be smaller than the laser spot size, and there are many factors that affect this value: laser refraction, microscopic contaminants, resin chemistry, and much more. The Form 2’s minimum feature size on the XY plane is about 150 microns-only 10 microns larger than its 140-micron laser. This means that the printer can reliably produce XY features as small as 150 microns, about the size of a human hair. As the intended line widths get smaller than 150 microns, the measured interval starts to deviate significantly from the ideal.
We put it to the test to see if this ideal resolution holds true.Īs the print’s line width decreases from 200 to 150 microns, the ideal values are within the 95% confidence interval of the measured value. The Form 2 has a laser spot size of 140 microns ( FWHM), which should allow it to print fine details on the XY plane. Practically, how does XY resolution affect your 3D prints? In order to find out, we decided to test the Form 2 SLA 3D printer. To truly know a printer’s XY resolution, it’s important to understand the science behind the number. Yet this number is not always included in spec sheets, and when it is, the published value is not always accurate.
