Compression Strength Testing Results

Welcome to our downloadable product for compression strength testing data for 3D resin. This product contains valuable information for those in the 3D printing industry who want to ensure the strength and durability of their resin-based prints. Our comprehensive testing data provides insights into the compression strength of various 3D resin materials, allowing you to make informed decisions about which resin to use for your specific application. By downloading this product, you will have access to reliable and accurate data that can help you improve the quality of your 3D printed parts and products.

Data

Below are the key points of our compression strength measurements (kgf) for 3D resin:

• We conducted 60 compression strength measurements for uncured resin.
• We conducted 60 compression strength measurements for cured resin with a 30-minute curing time.
• We conducted 31 sets of 5 compression strength measurements for resin that cured from raw (0 minutes) to 30 minutes, with 5 samples in each set.

Sample Results

Based on the results presented above, there are several ways you can utilize the data. For instance, you can compare the data with other brands/models to determine which resin is stronger. Additionally, we have provided sample tests and summary graphs for your convenience.The results presented below are for illustrative purposes only and should not be taken as the actual results you will obtain. These examples are included to give you an idea of the type of results you may expect from the downloadable files provided.

One of the statistics we have included compares the raw and cured data. From a sample test, we observed that the cured group had a mean strength of 75.197 kgf, while the uncured group had a mean strength of 59.368 kgf. This indicates that the curing process increased the strength by 27%.

The second point we'd like to highlight is the comparison graph of raw and cured resin. This plot is based on data sets 1 and 2, with the Y-axis representing strength (higher values indicate greater strength), and the X-axis representing the sample sequence. It's important to note that the sample sequence is not paired - for instance, sample number 5 in the raw resin group has no correlation to sample number 5 in the cured group.

From the graph, we can observe that cured resin (represented by open circles) generally exhibits higher strength compared to the uncured ones.

Our third point highlights the effect of curing time on the strength of 3D resin, as depicted in a graph based on data set 3. We conducted curing at one-minute intervals from 0 to 30 minutes, with five samples collected for each time interval.

Upon visual inspection, we can deduce that resin needs to be cured for a minimum of 15 minutes to achieve optimal strength. The data can be further analyzed using statistical methods such as nonlinear regression using Weibull model.

Here are some additional details about the testing methodology:

• The strength test unit used was kgf.
• The samples used in the tests were square-shaped, measuring 20 mm by 200 mm, with a thickness of 1 mm.
• We conducted the tests using a digital push-pull meter.
