Kenyan and Zimbabwean Researchers Study 3D Printed Polymer/PLA on Fabric

Share this Article

Researchers from Kenya and Zimbabwe are tackling more complex 3D printing adhesion and material topics in their recently published, ‘Use of regression to study the effect of fabric parameters on the adhesion of 3D printed PLA polymer onto woven fabrics.’ Familiar with the benefits of 3D printing, and its potential for use with a wide range of materials and fabrics, authors Nonsikelelo Sheron Mpofu, Josphat Igadwa Mwasiagi, Londiwe C. Nkiwane, and David Njuguna experiment further with polylactic acid (PLA) polymer onto a variety of fabrics, including cotton, polyester, and acrylic.

FDM 3D printing in textiles, while previously extended to the creation of fabric-polymer structures has given researchers challenge, mainly in adhesion due to surface texture. Improvement of such issues could open the door to a much wider range of fabric-polymer combinations. In this research, the scientists created 15 fabric samples, customized using SolidWorks, sliced with Cura, and then 3D printed with PLA. The team then tested the samples for the following:

  • Fabric areal density according to ASTM D3776.
  • Fabric ends/inch according to ASTM D3775.
  • Fabric picks/inch according to ASTM D3775.
  • Warp and weft count according to ASTM D1059-01.
  • Fabric thickness according ASTM D1777.
  • Fibre type according to American Association of Textile Chemists and Colourists (AATCC) 20.

Assessments were based on how texture felt to the human hand, whether smooth or rough, hard or smooth, stiff or limp. A panel of students was chosen to test the surfaces with their eyes covered to ensure judgment based purely on texture and not visuals. They were asked to grade the fabric on a scale on one to five, with one being smoothest and five being roughest.

The researchers noted average scores for the samples, documenting a clear effect on adhesion force. As all the properties being examined (fabric areal density, warp, and weft count, fabric thickness and fabric roughness) were increased, adhesion force increased too—with the opposite being noted for the ends/inch and picks/inch which were negatively correlated to adhesion force.

“Considering the fiber types used to manufacture the fabrics (acrylic, cotton, polyester/cotton blend and polyester), tests showed that the acrylic based fabrics displayed the highest adhesion force to PLA with polyester based fabrics showing the lowest adhesion force,” concluded the researchers.

While 3D printing and additive manufacturing processes have already offered enormous contributions to nearly every industry, refining the technology has become critical for many users—on all levels—from studying typical problems and making improvements in construction printing to experimenting with ultrasonic vibration, and creating other new filaments, along with using 3D printing materials in fashion, often as additional applications for accessories and items like handbags too.
