Raise3D Sandblaster B520 – Automated Post-Processing for SLS 3D Printing

The Raise3D Sandblaster B520 is an industrial automated blasting system designed for cleaning and finishing polymer parts produced using powder bed technologies such as Selective Laser Sintering (SLS).

Combining automatic and manual blasting capabilities with an enclosed processing chamber, programmable parameters and the innovative Easy Swap Basket, the B520 helps manufacturers achieve consistent surface finishes while reducing manual post-processing work.

The B520 is a valuable addition to the Raise3D RMS220 SLS Production System and is also compatible with suitable powder bed printing systems from other manufacturers.

Why Choose the Raise3D Sandblaster B520?

The B520 automates an important stage of the SLS post-processing workflow, helping businesses improve productivity and achieve more consistent results.

Automated SLS post-processing: programmable blasting cycles reduce manual processing requirements.
Easy Swap Basket: interchangeable baskets simplify part handling, transport and temporary storage.
High processing capacity: recommended batch capacity of up to 30 liters with the large blasting basket.
Automatic and manual blasting: combine automated batch processing with targeted cleaning of complex geometries.
Precise process control: adjustable parameters for consistent surface treatment.
Integrated HEPA filtration: supports dust management within the enclosed blasting environment.
Optional polishing module: extend the system with automatic polishing functionality.
Broad compatibility: supports Raise3D RMS220 and suitable SLS, MJF and other powder bed printing systems.
Efficient operation: according to Raise3D, the automated workflow requires less than five minutes of manual handling per cycle.

Automated Blasting for Consistent Surface Quality

SLS 3D printing produces parts by selectively fusing thin layers of polymer powder. After printing, residual powder may remain on external surfaces, inside openings or around complex geometric features.

Removing this powder is an essential part of the post-processing workflow.

The Raise3D B520 uses a controlled flow of blasting media to clean printed components and reduce the characteristic powder-based surface texture.

Automatic Blasting Mode

In automatic mode, the B520 processes multiple parts within a single batch.

Programmable parameters allow different production batches to be treated under comparable conditions, supporting consistent and repeatable results.

This is particularly beneficial for companies regularly manufacturing larger quantities of SLS components and looking to reduce the need for fully manual blasting operations.

Manual Blasting Mode

For parts with deep recesses, difficult-to-reach surfaces or delicate details, the B520 also supports manual blasting.

Operators can perform targeted finishing when certain areas are not sufficiently accessible during automatic processing.

Combining both modes provides greater flexibility when processing components with complex geometries.

Easy Swap Basket – Efficient Handling with Interchangeable Baskets

One of the distinguishing features of the Raise3D B520 is the Easy Swap Basket system.

The interchangeable baskets support part transportation, processing and temporary storage, helping streamline the workflow between different post-processing stages.

The B520 supports two basket sizes:

Basket	Dimensions	Recommended Batch Capacity
Standard basket	Ø 262 × 520 mm	10 liters
Large basket	Ø 467 × 520 mm	30 liters

The large basket provides additional space for processing larger parts or higher-volume production batches.

Actual loading capacity depends on part geometry, dimensions, basket loading and the required surface finish.

Controlled Blasting Media and Process Parameters

The B520 supports several blasting media, including glass beads and plastic media.

The recommended particle size is 200–300 µm, with blasting media supplied from an integrated hopper.

The system features:

9-liter blasting media hopper
Approximately 14 kg glass bead capacity
15-liter waste hopper
Programmable blasting parameters
Controlled airflow and media delivery

By adjusting process parameters to the printed material and component geometry, users can balance cleaning efficiency, surface quality and processing time.

Optional Polishing Module for Enhanced Surface Finishing

In addition to automatic and manual blasting, the Raise3D B520 can be upgraded with an optional polishing module.

This enables an additional automated finishing process designed to improve the surface characteristics of suitable polymer components.

The polishing module is an optional accessory and is not included in the standard B520 configuration.

How Does the B520 Differ from AMT PostPro Vapor Smoothing?

The Raise3D B520 and AMT PostPro systems perform different functions within the SLS post-processing workflow.

The Raise3D B520 uses mechanical blasting to remove residual powder and treat the surfaces of printed parts.

The AMT PostPro SFX and SF2X use controlled vapor smoothing technology to create smoother surfaces on compatible polymer components.

Depending on the application and material, these technologies can complement each other in a professional manufacturing workflow.

Compatible with Raise3D RMS220 and Other Powder Bed Printers

The Raise3D Sandblaster B520 is designed as part of a professional SLS production workflow.

Combined with the Raise3D RMS220 SLS 3D Printer and the C220-P Cleaning Station, it creates an efficient workflow in which printing, unpacking, cleaning and blasting are organized as separate production stages.

A typical workflow includes:

3D printing: manufacture polymer parts using the Raise3D RMS220.
Cooling and unpacking: remove printed parts from the Build Unit.
Powder handling: remove and process excess powder using the C220-P Cleaning Station.
Automated blasting: clean residual powder and treat part surfaces using the B520.
Optional finishing: perform additional polishing or vapor smoothing when required.

The B520 is not limited to Raise3D printers. It can also process compatible parts produced using third-party SLS, MJF, SAF and HSS systems.

Applications of the Raise3D B520

The B520 is suitable for professional environments where powder bed printed parts require regular cleaning and finishing.

Typical applications include:

Functional prototypes and end-use components
Industrial polymer parts
Technical housings and machine components
Complex geometries with internal or difficult-to-reach surfaces
Small and medium production batches
Professional 3D printing service providers
Batch processing of compatible PA11, PA12 and other polymer components

By automating the blasting process, manufacturers can achieve more consistent processing across recurring production batches.
