These are the simple three steps that every user needs to follow pre-printing. Such simple navigation makes the pre-printing phase completely straightforward even for the first-time user.

Intuitive Software

The workshop is a fairly simple and easy-to-use software that completes the entire process of slicing in five simple steps starting from Import, Layouting, supports creation, Previewing, and finally Exporting.

The step that gets most confusing for any user is support creation. But, don’t worry! Wanhao has taken care of this in advance.

Depending on the geometry, the software automatically suggests support as well as bracing creation making things easier for newbies in the field of 3D printing.

Moreover, advanced users can monitor as well as regulate minute settings and customize the print quality accordingly. Some of the typical criteria that the software allows to amend are overhangs, interval, tip diameter, etc.

Also, Workshop has a unique feature that most other software does not offer. AI selecting allows users to get a free hand with high intelligence.

In addition, the application permits operators to view their design in a multi-split preview mode that enables them to capture flaws in design pre-hand and ensure that they are not reflected in the printed object.

High Wavelength UV Light Source

Duplicator D7 Plus is equipped with a UV light source of 395 to 405-nanometer wavelength. Coordinating with an HD LCD screen offering a 2560 * 1440 pixels resolution the printer makes it possible to build an object with 35-micron layer resolution irrespective of the intricacy level in its geometry.

Based on DLP 3D printing technology, D7 Plus cures liquid resins such as Tough, Flexible, high temperature, etc. This allows users to not only create parts of varying geometry but also from distinct resins.

DLP 3D printing stands for Digital Light Processing. It is one type of vat polymerization just like SLA i.e., Stereolithography 3D printing technology. In it, a light source of high wavelength is used for curing the liquid resin.

The main difference between SLA and DLP 3D printing technology is the use of the HD LCD screen which decreases the overall 3D printing time.

That’s the reason why DLP 3D printers are known to print faster maintaining the quality that SLA 3D printers claim to achieve. The resolution of a DLP 3D printer directly corresponds to the resolution of the LCD screen.

The cost of 3D printing a part of a functional prototype using a DLP 3D printer is higher than FDM 3D printing technology. But on the other hand, it offers finishes that are almost impossible to achieve with FDM 3D printers.

However, when compared with SLA 3D printers, the cost is about the same and the only difference that remains is in the print speed.

Print Quality
