SLA Vs FDM Printing, What type is right for you?

Not sure what printing method to choose?

It will mainly come down to the resolution that you need. FDM printing (black model on the left) will have visible layer lines unlike SLA printing (grey model on right). The downside is that SLA costs significantly more to print than FDM, and also can take longer to finish a print. SLA prints also require a bit of post processing including removing supports, an IPA bath, and UV curing. These services are included with all our SLA prints.

SLA Printing

Amazing results do not always come easy. Higher printing costs are due to more expensive materials compared to FDM, and the amount of post processing required. After every print is finished, supports must be removed and sanded by hand to remove any traces. Then the print is bathed in an IPA bath to removed left over resin. Finally, the print is UV cure anywhere from 960 to 90 minutes to cure the resin and provide a strong print. SLA is best for prints with fine details.

FDM Printing

This is the printing style when most people refer to 3D Printing" as this method is the most popular, and also the best value. Layer lines will be visible and parts can feel light depending on their infill setting. Parts are generally easy to print and post process. Most supports can be snapped off by hand, or bathed in a vat of water for water soluble support removal. FDM can also struggle with fine details and surface smoothness.
