Understanding 3D Resin Printers vs. Filament Printers Blog

Just when you thought you knew everything about 3D printers, we are here to tell you that not all 3D printers are created equal. Specifically, 3D resin printers and 3D filament printers. In fact, they are very different when it comes to materials. For example, one creates layers by curing liquid resin with light. The other uses filament by creating layers upon layers of melted plastic spring. Because they are among the most commonly used 3D printers, it’s important to understand their differences to determine which one best suits your particular project.

Assessing the Similarities and Difference between Filament and Resin Printers

When comparing the two most popular types of 3D printers there are several key factors worth considering when making the best choice. The following may be able to help.


Before making a printer decision, think about the objects you are printing and the quality you hope to get. Filament 3D printers rely on nozzle size, extruder precision, and adhesion of layers when determining quality. Errors such as shrinkage, shifting, and warping are common when filament printers are used due to the way in which the layers are gradually squeezed together. These issues can be fixed post production. Yet, resin printers use a laser, which eliminates errors and can better produce fine details. The results using a resin 3D printer yield high-quality, precise products. If you want the best quality and finest results, a resin 3D printer is your best choice.


Filament and resin are very different in price as are time required and accessories. When it comes to cost, a filament is far more affordable. For example, a spool of filament costs about $25, while a tank of resin is $40 or more. A liter of resin can run twice that cost. If you are trying to do the job on a budget, filament is your best option.


Quality and cost of the job often come down to difficulty of design. While printing is essentially the same level of difficulty, the post-processing is what takes a little extra work. The challenge with resin printers is that removing the final print can be tricky when there is extra resin leftover. Before a project is complete it is sometimes placed in an ultraviolet oven and wiped with isopropyl alcohol. For that reason, filament printers are slightly less technical and difficult.

Deciding on the right 3D printer for your needs really depends on what type of object you want to create. If you want to work with low-cost materials for your hobby or quick project, then filament might be the best choice for you. However, if durability, strength and quality are of utmost importance, then a 3D resin printer is probably your best option. If you have any questions, we are here to help!
