Abstract
Present paper compares the copper electroplating on FDM (Fused deposition modelling) parts through two different routes. The two routes are: (i) Method of electroplating using chromic acid for surface preparation (ii) Method of electroplating using aluminium charcoal (Al-C) paste for surface preparation. Same plating condition is used for both the routes adapted. The result proposes that better copper deposition occurs using the Al-C paste than method using chromic acid for surface preparation. However, it was observed that in few samples, problem of shell cracking occurs in Al-C route, the reason for which is dissolution of paste at high operating condition during electroplating. Finally, the conclusion was made that Al-C paste at suitable operating conditions can be used for electroplating of FDM processed ABS parts. Copyright © 2017 VBRI Press.
