3D printing with resin: the good, the bad, and the ugly

Three-dimensional printing has come a long way since its inception, with the technology continuously evolving and improving. 3D printing with resin is just one of the latest advancements in the field, offering users the ability to create highly detailed and accurate prints. However, as with any technology, there are pros and cons to using resin for 3D printing. In this blog post, we’ll delve into the good, the bad, and the ugly of 3D printing with resin.

The Good

One of the biggest advantages of 3D printing with resin is the level of detail that can be achieved. Compared to traditional filament-based 3D printing, resin prints offer a much higher resolution. This means that users can produce highly intricate and detailed objects, making it an ideal choice for applications such as jewelry, figurines, and other highly detailed objects.

Resin printing also allows for the creation of complex geometries that would be difficult or impossible to produce with traditional 3D printing methods. This is because the resin is capable of filling in small gaps and crevices in the model, resulting in highly accurate and precise prints.

Additionally, resin prints have a smoother surface finish compared to filament prints, making it ideal for applications where a high level of detail is required. The smooth surface finish also means that the prints require less post-processing work, saving time and effort.

The Bad

One of the main downsides of 3D printing with resin is the cost. Resin printers are generally more expensive than traditional filament-based printers, and the cost of resin itself can be quite high. While the cost of resin has come down over the years, it is still more expensive than traditional filament spools, which can increase production costs.

Another issue with resin printing is the time it takes to produce a print. Compared to filament printing, resin printing can take much longer to produce. This is because the resin must cure layer by layer, which can be a slow process. This can lead to longer production times and increased production costs.

The process of cleaning up after resin printing can also be a messy affair. Unlike filament printing, which produces little to no waste, resin printing can be messy and require more cleanup. The resin is often toxic and requires special handling, making it more difficult to work with.

The Ugly

One of the biggest concerns with 3D printing with resin is safety. Many resins contain toxic chemicals that can be harmful if ingested or inhaled. It is essential to wear gloves and a mask when working with resin to avoid skin contact and inhalation of fumes. Proper ventilation is also necessary when using a resin printer.

Disposing of used resin can also be an issue. Resin cannot be disposed of in the same way as filament, and proper disposal methods must be followed to avoid contamination of the environment. It is essential to follow the instructions provided by the manufacturer when disposing of used resin.


In conclusion, 3D printing with resin has both advantages and disadvantages. While it allows for highly detailed and accurate prints, it can also be costly and time-consuming. The toxicity of the resin and its proper disposal must also be taken into account. It is essential to weigh the pros and cons of resin printing before investing in a resin printer and to take the necessary safety precautions when working with resin.

As the technology continues to evolve, it is likely that the advantages will increase and the disadvantages will decrease. Nonetheless, it is essential to consider both the positive and negative aspects of resin printing to ensure that it is the right choice for your project.
