Review on NanoDLP Software

In this article we present NanoDLP Slicer or Editor for UV DLP and DUP 3D printers in a short review. Interesting contribution for UV resin users from third party manufacturers, such as DruckWege Resins and others.

Short overview UV DLP Slicer – NanoDLP

  • NanoDLP (3D editor) –
  • Free Software
  • No registration required
  • Tested Version Build 2185
  • Web interface can be used by all common operating systems
  • NanoDLP is not a program for the preparation of raw models.

First of all: NanoDLP is not a software for preparing raw models for printing. Although NanoDLP offers the rudimentary features for this, the fact that the models cannot be rotated in discrete steps, but only freehand with the mouse, makes viewing, aligning and trimming the models extremely difficult.

The following example shows the representation of a 3D model in space, where the chess-like surface represents the base plate. The model shown is the DruckWege calibration model.

One should pay attention that the model lies flat to the baseplate, what one can trim in Z-axis with steps (unit unclear) and the MOVE – button. The rotation for viewing, but also for aligning the model, is extremely confusing.

Controlling the 3D printer with NanoDLP

In general, the software is designed to control the existing DLP or DUP 3D printer. Therefore you can use the software above all:

  • configure the traverse path of the Z axis
  • calibrate the display
  • Counteract inaccuracies in the illumination of displays with a mask
  • adapt the printing process using GCODES
  • Create resin profiles, which then also have their own GCODES.
  • Resin profiles with NanoDLP

The last point in particular, the management of different resin profiles, has been very well implemented and is a helpful application, especially when working with third-party resins. Many details per resin can be configured, so you can quickly get the right settings for each print. This makes it easy to create a small library, which also helps to calculate the resin (production costs) of the object on a flat-rate basis.

Layer height, exposure times for the base and standard layers, waiting times until the next exposure of the current layer or when lifting the baseplate. The control can be configured very precisely, so that also the acceleration is freely selectable.

Here you get an insight into common settings:

Special attention should be paid to details such as acceleration, with restrictions for small distances.

The compensation of unevenly exposed displays via a mask in order to solve possible exposure problems of the display is a feature that pure slicing software cannot do.


In summary, one can say that NanoDLP does what it is supposed to do: control a printer. But you can’t expect that it can be used to process models or supports. Even a simple alignment of a model can be a test of patience.


  • No installation necessary (browser-based)
  • No USB sticks necessary
  • Printer can be operated over the network without touching it
  • Masking is adjustable


  • Rendering takes place in the browser and is therefore dependent on the computer of the currently used computer and browser.
  • Slicing usually takes place on the printer, usually a Raspberry Pi. This can limit the size and complexity of the model to be sliced due to the low RAM and CPU power.
  • No possibility to rotate the model in discrete steps
    Support structures are not user-friendly to design and edit.
