A Guide to Post-Processing Tools in 3D Printing Services

Advanced 3D printing technologies have revolutionized the manufacturing process together with design through their modern printing methods. Many businesses in Malaysia rely on 3D plastic printing services for prototyping and production, while the demand for metal 3D printing in Malaysia continues to grow. The process of post-processing serves as an essential requirement for achieving excellent final quality standards in 3D printed objects. The following guide introduces the vital post-processing equipment along with nearly every technique required to accomplish flawless 3D printed projects.

Cleaning 3D Printed Products

After a 3D printing job, cleaning is the first step. The method varies depending on the printing technology used:

  • FDM Printing: Support structures need to be removed. This can be done manually or by dissolving the support material in a biodegradable cleaning solution.
  • SLS or MJF Printing: The process of clearing away surplus powder used in Selective Laser Sintering (SLS) and MultiJet Fusion (MJF) printing utilizes compressed air together with media blasters. The recycled powder creates less waste during production.
  • SLA Printing: Parts from Stereolithography (SLA) 3D printing are washed with Isopropyl Alcohol (IPA) to remove liquid resin, then dried with an air gun.

Fixing

Any small cracks or gaps in your parts can be filled during post-processing. Fillers or hardeners are used to fix these issues and prepare the parts for the next stage. Open post-processing opportunities enable you to fill minor fractures that appear in your printed parts. The combination of fillers along with hardeners functions to resolve printing irregularities and equip the components for upcoming production phases. Addition of gluing or welding operations becomes necessary to merge separate printed parts.

Curing

Curing forms an essential part of enhancing the total strength found in your 3D printed structures. When working with SLA prints UV light serves to perform material hardening while boosting mechanical properties. The curing process might result in brittleness when performed to an excessive extent.

Surface Finishing

Once the primary post-processing stages are completed, surface finishing improves the appearance and feel of your parts. Sandpaper is commonly used to smooth out imperfections. For a polished, smooth surface, vapor smoothing or vapor sealing techniques can be applied. We also offer vapor smoothing processes that make your parts stronger, smoother, and watertight.

Colouring

Finally, your 3D printed parts can be painted to achieve the desired colour. The complete process begins with sanding before choosing a suitable primer followed by multiple paint coats application. The PolyJet3D print system enables users to produce colorful objects with precise color representation. The technological requirements for this system involve substantial initial spending as well as recurring expense for maintenance.

Get the Right Team on the Job

Post-processing is an essential stage that ensures your 3D printed parts meet the desired specifications. The final quality depends on the skills and equipment of your 3D printing provider.
