“…Therefore, many processes modifying the surface and bulk properties have been developed to improve their biocompatibility [78]. Examples include surface laser engineering [63] and coating with natural biomaterials such as collagen [16]. With the development of composites materials, the combinations of biomaterials for making porous scaffolds have become enormous.…”

Scaffolds represent important components for tissue engineering. However, researchers often encounter an enormous variety of choices when selecting scaffolds for tissue engineering. This paper aims to review the functions of scaffolds and the major scaffolding approaches as important guidelines for selecting scaffolds and discuss the tissue-specific considerations for scaffolding, using intervertebral disc as an example.

“…Commonly used surface texturing techniques for UHMWPE are electrical discharge etching [110] and laser surface engineering [111]. Laser micro-machining is now widely used to modify the 3D surface textures of UHMWPE at both micro-and submicro-metre scales.…”

“…Laser micro-machining is now widely used to modify the 3D surface textures of UHMWPE at both micro-and submicro-metre scales. This technique becomes a good alternative to a standard photolithographic process because it is rapid and clean [111]. Using experimental and/or simulation methods existing studies investigated the effects of dimple size, depth and area density on the friction and wear properties of UHMWPE and its counterpart.…”

Wear Performance of UHMWPE and Reinforced UHMWPE Composites in Arthroplasty Applications: A Review

Abstract:As the gold standard material for artificial joints, ultra-high-molecular-weight polyethylene (UHMWPE) generates wear debris when the material is used in arthroplasty applications. Due to the adverse reactions of UHMWPE wear debris with surrounding tissues, the life time of UHMWPE joints is often limited to 15-20 years. To improve the wear resistance and performance of the material, various attempts have been made in the past decades. This paper reviews existing improvements made to enhance its mechanical properties and wear resistance. They include using gamma irradiation to promote the cross-linked structure and to improve the wear resistance, blending vitamin E to protect the UHMWPE, filler incorporation to improve the mechanical and wear performance, and surface texturing to improve the lubrication condition and to reduce wear. Limitations of existing work and future studies are also identified.

“…8 Industrial applications using this technique range from high-throughput steel fabrication, to inkjet and fuel-injection nozzle fabrication, 9,10 to high-resolution manufacturing and texturing of stents or other implantable biomaterials. 11 At a smaller scale, inexpensive benchtop laser cutting and engraving systems can be purchased by the hobbyist or small company for artistic and architectural renderings. More recent developments in LDWϪ include chemically assisted techniques such as laser-drilling ceramics or biomaterials and laser-induced backside wet etching (LIBWE) of glass.…”

Direct-write techniques enable computer-controlled two-and three-dimensional pattern formation in a serial fashion. Among these techniques, the versatility offered by laser-based direct-write methods is unique, given their ability to add, remove, and modify different types of materials without physical contact between a tool or nozzle and the material of interest. Laser pulses used to generate the patterns can be manipulated to control the composition, structure, and even properties of individual three-dimensional volumes of materials across length scales spanning six orders of magnitude, from nanometers to millimeters. Such resolution, combined with the ability to process complex or delicate material systems, enables laser direct-write tools to fabricate structures that are not possible to generate using other serial or parallel fabrication techniques. The goal of the articles in this issue of MRS Bulletin is to illustrate the range of materials processing capabilities, fundamental research opportunities, and commercially viable applications that can be achieved using recently developed laser direct-write techniques. We hope that the articles provide the reader with a fresh perspective on the challenges and opportunities that these powerful techniques offer for the fabrication of novel devices and structures.
