It is biocompatible, biodegradable and bioresorbable, degrading cleanly into carbon dioxide and water, and is widely used in biomedical, tissue-engineering and low-temperature prototyping applications.\u003c\/p\u003e\n\u003ch4\u003eApplication framework\u003c\/h4\u003e\n\u003cp\u003eDesigned for direct Selective Laser Sintering of functional PCL parts, where the printed part itself is made of PCL (unlike sacrificial binders, this powder remains in the final part). Its ultra-low melting temperature allows gentle, low-energy fusion on a cold or minimally heated bed. Typical fields are biomedical scaffolds, tissue engineering, drug-delivery carriers and low-temperature prototyping, where biocompatibility, flexibility and controlled bioresorption are required.\u003c\/p\u003e\n\u003ch4\u003eTypical applications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eSLS printing of flexible, biodegradable and bioresorbable PCL parts\u003c\/li\u003e\n\u003cli\u003eBiomedical scaffolds and tissue-engineering structures\u003c\/li\u003e\n\u003cli\u003eDrug-delivery carriers and controlled-release devices\u003c\/li\u003e\n\u003cli\u003eLow-temperature, low-energy SLS prototyping on printers with minimal or no bed heating\u003c\/li\u003e\n\u003cli\u003eFlexible, soft-touch functional parts where high elongation and toughness matter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eMeasured physical properties\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePolymer type: semi-crystalline aliphatic polyester PolyCaproLactone (PCL)\u003c\/li\u003e\n\u003cli\u003eMelting temperature: 58-65ºC (ISO 11357)\u003c\/li\u003e\n\u003cli\u003eGlass transition temperature: approximately -60ºC (ISO 11357)\u003c\/li\u003e\n\u003cli\u003eDensity: 1.14 g\/cm³ (ISO 1183)\u003c\/li\u003e\n\u003cli\u003eMaximum particle size: \u0026lt;150 microns\u003c\/li\u003e\n\u003cli\u003eLowest melting temperature of the 3Dresyns SLS functional powder range, enabling cold low-energy SLS printing\u003c\/li\u003e\n\u003cli\u003eThermal degradation well above the melting point (clean burnout to carbon dioxide and water)\u003c\/li\u003e\n\u003cli\u003eResolution: up to 50 microns depending on the chosen particle size grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eTypical mechanical properties of the bulk polymer*\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eTensile strength: 16-26 MPa (ISO 527-2)\u003c\/li\u003e\n\u003cli\u003eTensile modulus: approximately 400 MPa (ISO 527-2) — low modulus, flexible material\u003c\/li\u003e\n\u003cli\u003eElongation at break: very high, typically \u0026gt;300% (ISO 527-2) — highly ductile\u003c\/li\u003e\n\u003cli\u003eFlexible, tough behaviour with high extensibility\u003c\/li\u003e\n\u003cli\u003eBiocompatible, biodegradable and bioresorbable;
