Objective: This case series evaluates the safety and effectiveness of 3D-printed scaffold in chronic wounds. The scaffold is a composite of natural and synthetic materials, and can be prepared in the form of powder or membrane.
Method: We recruited patients with pressure ulcera (PU) and/or a diabetic foot ulcers (DFU). We used two methods: 3D-printed scaffolds alone, or 3D-printing powder mixed with platelet-rich fibrinogen (PRF). Clinicians and patients were asked to rate the scaffold's ease of application and comfort during use.
Results: A total of five patients were recruited; four with a PU and one with a DFU. For the patient treated with the 3D-printed scaffold membrane (n=1), their PU healed in 28 days, and for patients treated with the 3D-printed scaffold powder (n=2), their PUs healed in 54 days. For the patients treated with the 3D-printing powder mixed with PRF (n=2), the patient with a PU healed in 11 days, and the patient with the DFU healed in 14 days. All clinicians rated the 3D-printed scaffold as 'easy' or 'very easy' to use, and patients rated their comfort during wear and at dressing change as 'good' or 'very good'.
Conclusion: This study demonstrated that 3D-printed scaffold was convenient to use, have the potential to improve wound healing rates, and provided a safe and effective way for treating chronic wounds.

Bone tissue engineering scaffolds for bone defect treatment face numerous challenges, including mechanical mismatches and the lack of immune microenvironment modulation, often leading to implant failure. In this study, an innovative drug-loaded bioinspired ceramic/polymer composite scaffold was designed and fabricated using extrusion-based 3D printing technology, incorporating α-cyclodextrin (αCD) in a novel approach to improve interfacial compatibility and drug-loading efficiency. Hydroxyapatite (HA), the main component of natural bone, was employed as the inorganic phase to mimic the mineral structure of bone tissue.

Surface modification of poly(ε-caprolactone) (PCL) to facilitate interactions with high pI proteins is a strategy used to enhance 3D PCL scaffolds for tissue engineering applications. The approach of the current study was to firstly optimise the surface modification on 2D films and then apply to 3D scaffolds. Melt-pressed PCL films were grafted with 2-aminoethyl methacrylate gamma radiation induced grafting to introduce amine functional groups to the substrate surfaces.

This study developed a multifunctional 3D-printed polycaprolactone (PCL)-gelatin (Gel) scaffold reinforced with Bioglass particles (BGPs) or copper dopped BGPs (CuBGPs) to synergistically enhance angiogenesis and bone regeneration in rat model. The scaffolds were fabricated by infiltrating gelatin solutions containing BGPs or CuBGPs into the pores of 3D-printed PCL matrices, followed by freeze-drying.

Neuronal control of skeletal muscle function is ubiquitous across species for locomotion and doing work. In particular, emergent behaviors of neurons in biohybrid neuromuscular systems can advance bioinspired locomotion research. Although recent studies have demonstrated that chemical or optogenetic stimulation of neurons can control muscular actuation through the neuromuscular junction (NMJ), the correlation between neuronal activities and resulting modulation in the muscle responses is less understood, hindering the engineering of high-level functional biohybrid systems.

Treating infected wounds is a major clinical challenge, and concerns about bacterial resistance have driven the shift toward natural antimicrobials over antibiotics. Herein, a 3D printed scaffold wound dressing consisting of alginate (Alg) and fucoidan (F) was prepared, and Soluplus (Sol) nanomicelles (NMs) were used to load vanillin (Vn) as a lipophilic antibacterial agent into the 3D printed scaffold. Characterization analyses revealed that the fabricated scaffold exhibited a peak swelling capacity of 294.
