High im­pact plas­tic for flex­i­ble pro­to­types

DEMM Engineering & Manufacturing - - 3D TECHNOLOGY -

Strat­sys has in­tro­duced En­dur, an ad­vanced sim­u­lated polypropy­lene ma­te­rial for use with all Ob­jet EdenV, Ob­jet Con­nex, Ob­jet500 Con­nex3 and Ob­jet 30Pro 3D print­ers.

As a durable and f lex­i­ble ad­di­tion to the firm’s ma­te­ri­als port­fo­lio, En­dur of­fers both high im­pact re­sis­tance and elon­ga­tion at break, re­sult­ing in tough parts. The ma­te­rial has a heat­de­flec­tion tem­per­a­ture up to 129°F / 54°C (HDT @ 0.45MPa per ASTM D-648-06) and has ex­cel­lent di­men­sional sta­bil­ity for its ma­te­rial class.

These prop­er­ties make the new ma­te­rial suit­able for a wide range of form, fit and as­sem­bly ap­pli­ca­tions, such as f lex­i­ble liv­ing hinges, mov­ing parts, as­sem­bled parts and snap-fit parts such as those used for lids and pack­ag­ing case ap­pli­ca­tions.

In ad­di­tion, En­dur, which is avail­able in bright white, fea­tures a sur­face fin­ish with a smooth look and feel. This makes the ma­te­rial well-suited for pro­to­typ­ing house­hold ap­pli­ances, con­sumer goods, au­to­mo­tive parts and lab equip­ment.

“Beta field tri­als showed high user sat­is­fac­tion with En­dur for mod­els and pro­to­types of polypropy­lene parts,” says Strata­sys’ prod­uct di­rec­tor for ma­te­ri­als and ap­pli­ca­tions, Fred Fischer.

“Dur­ing beta test­ing, cus­tomers test­ing En­dur ac­knowl­edged its tough­ness and f lex­i­bil­ity, and they be­lieved the ma­te­rial would ad­dress fu­ture needs.”
