Standard settings for printing most of of our 3D resins in most SLA, DLP & LCD printers:
- Z layers are typically between 50-100 microns (lower or higher are also printable). The use of lower Z layers may require tuning of Z axis resolution with our Fine Tuner LB1 Bio, which can be sent as free sample upon request
- Exposure times are typically between 1-10 seconds for the fastest resins and 10-20 seconds for the slowest resins
- Depending on the power of your printer, the optimum exposure times will increase or decrease. Follow our detailed Instructions for Use. Measure and fill up the data, cure thickness vs exposure time, in the curing rate table for your specific printer specifications. Alternatively, order online the curing the table for your ordered 3D resins measured with similar light power specifications with this light meter*
- Typically 3 adhesion or bottom layers at 80 seconds are enough for having good cure and adhesion on the build platform for most resins
- Light off delay: 2 seconds
- Lift distance: 10 mm
- Lift Speed: medium value of the scale
- Retract speed: medium value of the scale
- Printing temperature: before printing warm viscous 3D resins, protecting them from room light to prevent their light curing, to around 30-35ºC to reduce their viscosity and adhesion to the resin tank
- low viscosity resins do not require any warming
Taking into account the broad range of printer specifications (light power variability) of different printer models of even the same printer technology the optimisation of the printing settings, such as light exposure times, are required for each resin and printer unit because all printers have different light power across the vat available for curing and printing 3D resins. Additionally, the light power also decays over cumulative operating time or working hours. As example, the following graph shows a typical light output decay vs cumulative operating time of standard multicolour RGB LCD panels, monochrome LCD panels, digital lamp projectors and LED projectors, all typically used in SLA, DLP & LCD 3D printers.
*Note: The curing rate table for each ordered 3D resin cured at 405 nm with a similar light power to your printer can be optionally ordered online for 40 Euro. For exact values we recommend you ordering the same light meter as ours, since the ordered curing rate table can be much more accurate after sharing your exact printer power. This will permit the 3Dresyns team to measure the curing rate table accurately with the same power as yours for fast & easy finding your optimum printing settings.

Calibration of 3D resins in 3D printers
Our free supplied calibration files will help you choose the right balance of printing speed, resolution, precision, and dimensional accuray of your prints (see 3Dresyns calibration file of the coin below with resolution up to to 2 microns).
3Dresyns Instructions for Use IFU are practical, scientific, intuitive, fast, and easy to follow. There is no need to understand any complex concepts, theories, and equations as shown in detailed in Fundamentals of Stereolithography by 3Dresyns
Printing of most 3D resins is easy with our calibration instructions, which show you to choose the right exposure times and printing settings for your chosen z layer thickness, as shown in this video:
Basic simple scientific methodology for non-scientists
- Our calibration stl files (including the horizontally positioned coin shown above: most critical or difficult orientation for getting high z axis accuracy) are available for confirmation of printability, and for determining the xyz printing resolution, precision, and dimensional accuracy of the chosen printing settings in your existing printer, before printing your own designs
- Our IFU will provide you a full fingerprint of the achievable printing speed, resolution, precision, and dimensional accuracy of your chosen 3D resin with your printer specifications
- The optimum printing settings for your chosen balance of printing speed, resolution, precision, and dimensional accuracy will be chosen by you, following our detailed IFU, with just some basic calibration steps
- Our IFU do not require the use of complex working curves, nor mathematical correlation formulae of several variables such as:
- Cd = Cure Depth (μm or mm) (cured layer thickness), Dp = Depth of penetration (mm), Ec = Critical Energy (J/mm2), E = Energy dosage per area or light irradiation dose (mJ/cm2), variables which are included in the working curve equation: Cd = Dp • In(E/Ec)
- Our IFU are intuitive, fast & easy, and do not need the understanding of any complex concepts and equations, nevertheless technical 3D resins require technical printers
Dimensional accuracy of 3D prints refers to how close the three spatial xyz dimensions of 3D prints are to the theoretical three spatial xyz dimensions of designed prints as defined in the stl file before printing. The stl file of 3Dresyns flat coin has 2 mm thickness (z axis) and 30 mm diameter (xy axis). The relative dimensional accuracy in the xyz axis can be easily measured by measuring the real diameter (xy axis) and thickness (z axis) of the horizontally positioned flat coin. For example, if the thickness of the printed coin is 2.1 mm. The difference between the theoretical and real value is 0.1 mm and the % difference is 0.1/2x100=5% which indicates the relative dimensional accuracy in the z axis. The same principle applies to the xy dimensional accuracy. If for example the diameter of the printed coin is 30.3 mm. The difference between the theoretical and real value is 0.3 mm and the % difference is 0.3/30x100=1% which indicates the relative dimensional accuracy in the xy axis.
Basic tools needed for calibration:

Black box printing vs clear box printing*
If you are after a "plug & play" printing solution, without any specific technical and safety requirements, then consider purchasing the original non-functional "fragile" & "me too cheaper" 3D resins supplied with the printers. For certain time they will print certain basic 3D resins, but sooner or later will fail due to several reasons. Learn about the common reasons for printing failure:
On the other hand, if you need to print technical functional materials with constancy (without variability) with high resolution, precision, dimensional accuracy, mechanical strength, and safety, and if you need specific functionality and performance properties, then explore our diverse 3D resin offering of multifunctional resins and 3D printing consulting services.
3Dresyns quality control of printing speed includes the measurement of the curing rate table of each made to order 3D resin at certain light power specifications at 405 nm a certain exposure times (5, 10, 15, 20, 25, 50, 75, and 100 seconds).
Do you need 3D printing consulting?
If you are fighting with your existing printer in a "black box" approach and feel that you need more control and understanding of the fundamental 3D printing variables affecting the performance, reliability and reproducibility of your work, or in case that you do not have a printer yet, or need a new one, and do not know yet which printer to buy?
