Resin as one of the general 3D printing materials, although there will be some post-processing processes, the surface of the finished product is smoother, the quality is higher, and the details are clearer. It has been favored by the majority of 3D printing enthusiasts.

The general price of resin consumables is about 100 yuan per catty. For some industries that can provide more fine surface quality, such as dental or high-end technology, precision industry, the price will be higher.

So saving consumables is what we should learn.

1. Reduce the size of the model: the consumption of 3D printing materials is closely related to the size of the model: the smaller the size, the less the consumption. You can scale the dimensions in the XYZ direction, or you can scale them separately.

2. Hollow model: material consumption is closely related to volume: the smaller the volume, the less consumption. So sometimes, the hollow out model is very necessary. There are two things to pay attention to in hollowing out model: wall thickness and drainage hole.

Minimizing wall thickness does look like a way to save money. However, if the wall thickness becomes thinner, the model will become fragile, and some regions of the model will be easily broken.

In addition, when printing the hollowed out model, the resin may be blocked in the model and cannot be discharged due to the layer curing. At this time, it is necessary to add drainage holes to drain the blocked resin from the hollow model.

3. Optimize the model structure: it is of great significance to optimize the 3D model structure and improve the printing success rate. For example, the thinner the outer wall, the lighter the model. The less resin used to print, the more money saving, but also more vulnerable.

This is particularly important when using the pull-up 3D printer, because the model is upside down and suspended, so the gravity (large model) and tension will be greater.

4. Avoid supports and bottom rafts: material consumption can also be improved by avoiding or reducing the use of supports and bottom rafts. Do not waste resin material, should effectively add support and bottom raft.

5. Overall printing: through overall printing, 3D printing can skip some assembly processes to reduce material consumption.

Of course, there are also some online price evaluations, which use a series of complex price algorithms, such as volume, surface area, to estimate the cost of 3D printing. 3D printing files can be uploaded online,

Use the price evaluation system to test how to set up the most economical material for 3D printing. Let's print our best model with the least amount of materials.
