Topic Information

Dear Colleagues,

Surface engineering plays a critical role in enhancing the functional properties and performance of materials across a wide array of applications, ranging from tribology and biomedical devices to microelectronics and photovoltaics. Similarly, advances in micro additive manufacturing technologies offer unparalleled precision in creating complex structures at micro- and nano-scales. The integration of these two fields holds great potential for developing next-generation functional surfaces and small-scale components with enhanced properties such as wear resistance, corrosion resistance, and tailored optical or thermal behaviour.

This call invites original research papers on the latest innovations, developments, and applications in surface engineering and micro additive manufacturing. Emphasis will be placed on both experimental and computational work that advances the understanding of surface modification processes, additive techniques, and the synergies between these areas.

Topics of interest include, but are not limited to, the following:

1. Surface Functionalisation and Modification Techniques

  • Surface texturing, polishing, and patterning;
  • Coatings: PVD, CVD, thermal and cold spray, ion implantation, and cladding;
  • Surface heat treatments and chemical etching;
  • Advanced surface technologies for thermal protection, corrosion resistance, and decorative applications.

2. Micro Additive Manufacturing Technologies

  • Two-photon polymerisation, vat photopolymerisation (VPP), and material extrusion (MEX);
  • Powder bed fusion (PBF) and micro-directed energy deposition (DED);
  • Aerosol printing, direct ink writing (DIW), and material jetting;
  • Micro-scale laminated object manufacturing (LOM) and electron beam techniques.

3. Computational Modelling and Simulation

  • Process modelling and simulation for surface modification and micro additive manufacturing;
  • Multiphysics simulations, computational fluid dynamics, and thermal–mechanical modelling;
  • Optimization and prediction of surface properties and process outcomes.

4. Applications of Surface Engineering and Micro Additive Manufacturing

  • Tribological surfaces and coatings for wear-resistant applications;
  • Surfaces for microfluidic devices, sensors, actuators, and biomedical implants;
  • Functional coatings for photovoltaic devices, optics, and decorative surfaces;
  • Soft electronics, soft actuators, and thermal protection systems;
  • Embedded sensors for soft robotics, structural health monitoring, and clothing.

This study investigates the effect of polymer film lamination on the tensile performance of wood fiber-reinforced polypropylene (WP) composites. Neat polypropylene (PP) and WP containing 25 wt% wood fiber were injection-molded and laminated with 0.1 mm PP or polyethylene terephthalate (PET) films using a compatible adhesive. Four configurations were examined: unlaminated (0S), single-sided half-length (1S-H), single-sided full-length (1S-F), and double-sided full-length (2S-F). Mechanical properties and fracture morphology were characterized by uniaxial tensile tests and scanning electron microscopy (SEM), alongside measurements of surface roughness. PET lamination produced the greatest strength enhancements, with 2S-F specimens achieving gains of 12% for PP and 21% for WP, whereas PP lamination gave minimal or negative effects, except for a 5% increase in WP. Strength improvements were attributed to surface smoothing and suppression of crack initiation, as confirmed by roughness measurements and SEM observations. PET’s higher stiffness and strength accounted for its superior reinforcement relative to PP. Fractographic analysis revealed flat regions near specimen corners—interpreted as crack initiation sites—indicating that lamination delayed crack propagation. The results demonstrate that PET film lamination is an effective and practical post-processing strategy for enhancing the mechanical performance of wood–plastic composites. Full article

The 316L stainless steel material boasts exceptional corrosion resistance and plasticity, among other benefits, and finds extensive application in automotive components, molds, aerospace parts, biomedical equipment, and more. This work focuses on the surface polishing of selective laser melting (SLM) 316L stainless steel using 1064 nm nanosecond laser processing and mechanical grinding. The influence of laser processing parameters on the surface roughness of SLM-316L stainless steel was investigated using an orthogonal experiment. After laser processing, the surface roughness of SLM-316L stainless steel was reduced from 7.912 μm to 1.936 μm, but many randomly distributed irregular micro-cracks appeared on the surface. EDS and XRD detections illustrated that iron oxides were generated on the surface of SLM-316L stainless steel after laser processing. Mechanical grinding was further performed to achieve a nanometer surface finish and remove the metal oxides and micro-cracks generated on the surface of SLM-316L stainless steel after laser processing. The AFM measurement results indicate that the surface roughness of SLM-316L stainless steel was reduced to approximately 3 nm after mechanical grinding. Moreover, the micro-cracks and iron oxides on the surface of laser-processed SLM-316L stainless steel were completely removed. This work provides guidance for the precision polishing of SLM-316L stainless steel. Full article

Additive manufacturing of optical, electrical, and mechanical components is a beneficial approach for the rapid prototyping of components and error elimination, with short turnaround times. However, additively manufactured components usually have rough surfaces that need post-processing, particularly for optical components, where the surface roughness must be a small fraction of the wavelength. We demonstrate an innovative and economical approach by dip-coating with the same resin used for printing in a simple post-processing step, providing high transparency to the 3D-printed optical components and reducing surface roughness while achieving perfect index matching of the coating layer. The surface roughness of the 3D-printed optical components drops to 5 nm (arithmetic average) after the dip-coating process. We observed significant performance enhancements after comparing the unprocessed optical components and the dip-coated optical components, including optical transparency and a shiny surface finish for previously rough surfaces.
