A Smart Slicer for Industrial Applications

A New Standard in Large-Format Slicers

BLADE, BigRep’s easy to use slicing software, allows for greater control of printing parameters on all BigRep large-format additive manufacturing systems. Its integrated estimation engine gives accurate printing time and material use predictions for unmatched planning and productivity. As one of the fastest and most precise slicers on the market, this cutting-edge software is optimized for industrial part slicing to make for a rapid, hassle-free start to printing.

Built on industry-standard software with key features and optimizations:

  • Specially designed for BigRep 3D printers
  • Range of options to reduce large-format print times and material use
  • Frequently updated BigRep material presets for fast, quality prints
  • Expert and basic UI modes for precision control and ease of use
  • Accurate print time and material use predictions
  • Automated batch production planning


BLADE’s user-friendly interface makes for a simplified printing experience. By optimizing for large-format parts and integrating presets for all BigRep-compatible materials, BLADE streamlines the industrial printing process to save users’ time and ensure successful, quality prints.

Latest stable version: 2.0.0 - Releases


Requirements/First Steps


  • Windows 10
  • Memory: 8GB or more
  • CPU: intel core i5 or better
  • GPU: dedicated graphics card recommended, but works on integrated as well

First Steps

Blade is heavily based on Ultimaker Cura. In particular, you will get quite far by the ordinary Cura documentation:

The following sections point out what are the differences and the explicit features of Blade in contrast to Cura.

Basic Settings Overview

If you hold the cursor over a setting you get a description of the setting and its effect.

Quality Presets:

  • "Quality" will result in a slower print, but gives a higher overall print quality.
  • "Medium" is faster than "Quality" and was known as "Speed" in previous Simplify3D Factory Files.

More presets might be added over time.

Z Seam Alignment:

  • Here you can chose where Blade is placing the retraction points.
  • With standard settings, Blade will work to place retraction points at less visible positions. This is suitable for most geometries. However, in some rare cases you have to do manual adjustments.
  • If you switch to "User Specified" you can choose a a X-Y coordinates as in Simplify3D. If you also check "Z Seam Relative" the position is relative the center of the model.

Gradual Infill:

  • This change the amount of infill gradually.
  • This produces a lower infill in the main body and higher infill closer to the surface of the part.
  • This reduces the printing time and amount of material needed.
Blade Workflows

The extruder setup in Blade should be the same as on the machine. If there is more than one physical machine, then there shall be for each physical machine a virtual representative in Blade.

For example it is possible to add two ONEs with different extruder setups. These will be saved locally on the user's computer and can not be easily transferred to another computer.

Extruders can be enabled and disabled by right clicking on the extruder in the main menu.

This is important as there are some setting that change if one or both extruders are enabled . If two extruders are enabled, Blade assumes that the user wants to perform dual extrusion.

So if only T1 (Extruder 2) is used, T0 (Extruder 1) should be disabled and the other way round.

How to add a printer

When Blade is opened for the first time you are asked to add a printer. Additional printers can be added later

  • Click on Printer Selection the top right corner and then on "Add Printer..."

  • You can also click on "Settings" in the menu bar and then on "Printer", "Add Printer..."
  • In the following menu you can add a printer and also change its name:

How to use Dual Extrusion

Both extruders must be enabled.

Dual extrusion with two or more models

  • Each model can be mapped to one of the extruders.

Dual extrusion with a different support extruder

  • Make sure you have the right material mapped to the correct extruder.
  • Also the model(s) should be connected to the extruder which is not used for support.
  • Then the "Support Extruder" need to be changed to the other extruder.

Prime Tower adjustments

  • Independent of how the dual extrusion is used, the prime tower should be adjusted.
  • Dependent of the height of the model, also the size of the tower needs to be adjusted to ensure it's stability and preventing it falling over.
  • To avoid oozing, the tower should be placed as near as possible to the model.

How to use Mixed Mode/Batch Printing

All at Once

What it does

All models will be printed at the same time. Called Layer-by-Layer in Simplify3D.

This means that the printer will print one layer of each model and than move to the next layer, and so on.

Why it should be used

All at Once is the default (if both extruders are enabled) and easier to use than "Mixed Mode".

In particular, this configuration is safe and you can print any scenario without taking care about safety distances.

How to use "All at Once"

If the second extruder is enabled, "All at Once" is the only possible mode. In particular, you cannot change it.
Otherwise, you can change the mode in "Special Modes/Print Sequence".

Good to know:

  • "All at Once" is the default value if both extruders are enabled. Otherwise, "Mixed" is the default.
  • It is easier to use than Mixed mode.
  • A disadvantage is the following: In case of a printer failure, all prints will be lost.
  • Printing results might be different for each model because the relative motions are different.
  • Printing time might be higher because of more travel moves.

Mixed/Batch Printing

What it does

Mixed printing mode replaces the standard Cura "One at a Time". Together with "Mixed" we offer the batch printing plugin (Menu→Extensions→Batch Printing) to get the full out if this mode.

To use the full potential of the print bed and still uses the advantage to print model by model the mixed mode combines layer by layer printing with model by model.

But instead of printing each model separate it uses row and columns to make the print safer.

Depending on the used printer the behavior is slightly different. The ONE and PRO starts at the front of the printer, while the STUDIO and STUDIO G2 start from the right.

Why it should be used

Mixed mode is more complex to use than "All at Once".

The benefit is that the models will be printed as they would be printed alone. Whenever a model is finished it can't be effected by a printer failure.

How to use Mixed mode

"Mixed" will be automatically enabled when you disable the second extruder.
You can alter the mode via "Print Sequence/Special Modes".

As already mentioned, the Mixed mode will do most of the work and chose the right mode depending on how the models are placed on the print bed. Placing can then be done via the batch printing extension automatically.

Print different models in one print:

  • Import all models
  • If needed, alter settings for specific models by "Per Model Settings"
  • If several models form a single part, group them together
  • Call "Menu→Extensions→Arrange objects for mixed mode"

Print a single model multiple times in one print:

  • Import the model (you can also import several models and group them together)
  • Call "Menu→Extensions→Populate build plate completely" for having the maximum number of copies.
    (Alternatively, you can call "Menu→Extensions→Populate build plate for sequential printing" for just populating the rows.
    Or with right click on the model and "Multiply Selected Model" you can create a specific number of models and then call "Menu→Extensions→Arrange objects for mixed mode")

Good to know:

  • Always check if the order is correct in the preview.
  • You can also use "Per Model Settings" for each model.
  • You can group or merge several models to one "part".
How to use Tandem Mode on the ONE

You need to disable "Extruder 1" to be able to activate the "Tandem Mode".
Than you can activate "Enable Tandem Mode" which is a "Special Modes" setting.

Important: The build plate will only be refreshed when a model is imported.
