Abstract

In this research, the effect of water-silica slurry impacts on polylactic acid (PLA) processed by fused deposition modeling (FDM) is examined under different conditions with the assistance of an adaptive neuro-fuzzy interference system (ANFIS). Building orientation, layer thickness, and slurry impact angle are considered as the controllable variables. Weight gain resulting from water, net weight gain, and total weight gain are the predicting variables. Results uncover the accomplishment of the ANFIS model to appropriately appraise slurry erosion in correlation with comparing real data. Both experimental and ANFIS results are almost identical with average percentage error less than 5.45 × 10−6. We observed during the slurry impacts tests that all specimens showed an increase in their weights. This weight gain was finally interpreted to the synergetic effect of water absorption and the solid particles fragmentations immersed within the specimens due to the successive slurry impacts.

Highlights

In recent years, polymer materials have a growing interest in different industrial applications under conditions of slurry impacts, such as pipelines exposed to slurry stream in refinery and offshore petroleum industry [1,2,3,4,5], and sewage systems [6,7]
Build orientation and layer thickness are the critical parameters affecting the Fused Deposition Modeling (FDM) process, and the impact angle parameter is a key factor connected with the slurry impact condition
The observed weight gain of the specimens was postulated to two reasons: (a) water absorption, and (b) the embedded sand particles in the surfaces of the specimens [36]

Summary

Introduction

Polymer materials have a growing interest in different industrial applications under conditions of slurry impacts, such as pipelines exposed to slurry stream in refinery and offshore petroleum industry [1,2,3,4,5], and sewage systems [6,7]. This growing attention to polymers is due to several factors: environmental requirements, cost reduction, corrosion in metallic counterparts, weight reduction, and electrical and thermal insulating properties [8]. The process starts with a filament which is heated and deposits successively by a nozzle on a printing bed
