Achieving a Smooth Finish on Additive Manufactured Aluminium Planes in 3 Steps

More and more industries are moving from traditional methods of manufacturing metal parts to additive manufactured components. A frequent choice of material used in 3d printing is the aluminum alloy, due to its cost, performance and manufacturability. Nonetheless, this material has a lower specific strength than others, making the post processing of the surface finish more difficult.

In this case study, we look at how you can achieve a smooth and polished surface finish on additive manufactured aluminium planes, without damaging the parts.

Client approached ActOn Finishing team to develop a process to allow him to achieve a smooth and polished finish on additive manufactured aluminium planes, without affecting the components’ geometry.

Smooth Finish on Additive Manufactured Aluminium Planes in 3 Steps

Find out how you can achieve a smooth and polished surface finish on additive manufactured aluminium parts, without damaging them.

After conducting our trials we achieved the final finish in a 3-stage process:

  • We first deburred the parts in the ActOn CDF machine with a mix of abrasive ceramic media, a liquid compound which acts like a cleaner and polisher on non-ferrous metals and water.
  • Then we achieved a smooth finish in the same machine, with a mix of low abrasive plastic media, same polishing compound and water.
  • In the final stage we polished the additive manufactured planes in the CPM10 High Energy Polishing Machine with pretreated agro-media. While the CPM10 machine is perfect for polishing small and delicate components, the pretreated media has been developed to produce a bright mirror finish.

The process benefits include:

  • The finishing results are consistent and repeatable.
  • Part’s geometry was intact after all 3 finishing stages.
  • The final finish was achieved in just 3 hours

Results

The smooth and polished finish required was achieved in only 3 hours without affecting the part’s geometry. Using the CDF and CPM10 technology along with ActOn consumables, client enjoys consistent and repeatable results every time, without the need of reworking or scraping the parts.
