Wuhan Easymade technology Co.,ltd developed the large 3DP sand printing system ( size: 1200mmx600mmx600mm )  in 2018, its performance index is up to the international level of similar products. the large Binder jetting sand 3D printing system can prepare single or multiple industrial nozzles for simultaneous printing according to the needs of customers, and the high speed printing control system is also developed. the single layer printing time of 1200mmx600mm can be completed in only 10-30(number of nozzles) seconds.

1. Technical programme

The binder jetting sand 3D printer developed by EasyMade technology gets rid of the shortage that traditional 3D printing equipment relying on imported laser and scanning system and the expensive cost, and also slow printing speed . The principle of the traditional 3D printing is the process from point to line to surface. The binder jetting sand molding equipment replaces the function of the laser and scanning system with the nozzle, and the molding way is directly from the line to the surface. The technology can print the sand core of any complex shape quickly, and then get the metal parts by pouring. the traditional 3d printing has requirements for the material of sand but the 3dpDP sand mold printing technology can use the original sand to print directly. Because of the advantage of low cost, fast, so our technology has been widely used in the field of casting.

Pros and cons to using 3D printing to create molds
1.Faster for large-scale applications
2.Better quality control

3.Cheaper than industrial molds

4.Less durable than industrial molds

5.Will require lots of trial and error
6.Molds require post-processing

Tools and supplies for 3D printing molds

Molds can be made using either filament-based or resin-based 3D printers. The approach to designing a mold using either of these 3D printer types aren't significantly different. A resin-based printer can print at a higher resolution, which means that layer lines aren't that much of a problem. However, filament-based printers are less expensive and much more common.

3D modeling software

If you're designing a mold, you will likely need to start with a 3D model of the part you're trying to reproduce. You will need a 3D modeling software, such as AutoCAD, to manipulate this model and make a negative copy out of it. Keep in mind that this is easier said than done and that there are certain principles to consider when designing a mold.


 

Final thoughts

Creating a mold is an unconventional of using a 3D printer, but it can be more practical in certain situations. Making identical parts from a 3D printer mold is simply faster and more practical if you want to churn out multiple copies. Just keep in mind that a cheap 3D printed mold will not be as heavy-duty as one made from plaster or metal.

If you've never tried 3D printing a mold before, then this would be a good weekend project. Just take your favorite design (ideally one with good symmetry) and try to make a mold out of it. You'll almost certainly learn a few good design lessons on the way.
