3D-printed bioabsordable polycaprolactone stent: The effect of process parameters on its physical features

Development of a radiopaque, long-term drug eluting bioresorbable stent for the femoral-iliac artery

“…22 In addition, previous studies on fabricating biodegradable stents based on 3D printing did not: make use of the clinically applicable FDA-approved materials, 23 result in a high quality shape, 24 or conrm applicability to native blood vessels. 25 In addition, no studies on stent exist that maintain a long-term drug release prole along with its radiopaque capability. In this study, a stent is developed containing the features of radiopacity and a long-term drug release prole, while various structural forms can be produced as well.…”

Stent’s Manufacturing Field: Past, Present, and Future Prospects

“…AM refers to processes used to create a 3D object in which layers of material are formed under computer control. The use of this technology for stent manufacture is recent [57][58][59][60][61][62][63][64] and could be a really interesting method to produce stent. Mainly, there are four different AM technologies in the stent field.…”

“…Although the results were promising, the traditional 3D printer presents some limitations to manufacture tubular devices such as stent. Guerra et al [59,64] design and implement a novel 3D tubular printer to BRS manufacture, the first full research paper that applies 3D-printing process based on FFF to manufacture a BRS stent with nontraditional printer. Their approach presented a new and interesting method to produce stents based on polymers in less than 2 min ( Figure 5).…”

Additive Manufacturing in Vascular Stent Fabrication

“…In 2018, Guerra et al [41] of University of Girona, Spain printed the PCL vascular stent (Figure 3.D) using the FDM technology. The relationship between the thickness of the stent and the temperature of the nozzle as well as the printing speed and the nozzle moving speed was summarized by a large number of experiments.…”
