Imprimarea 3D
Introducere
Ce este imprimarea 3D?
*AMF – Additive
Manufacturing File
De curând, echipamentele pentru
imprimare 3D sunt disponibile atât pentru
producția industrială cât și pentru
utilizatorii casnici.
Prin utilizarea imprimării 3D se pot crea
produse având aproape orice formă.

Un cap de imprimantă pulverizează după fiecare depunere,
un jet fin de adeziv, jet de adeziv ce solidifică punctual
pulberea astfel încât să fie respectat conturul tridimensional
al obiectului.
După fiecare ciclu de depunere a pulberii şi pulverizare de
adeziv, suprafaţa de lucru este coborâtă cu 0,1 mm –
corespunzător grosimii stratului de pulbere ce urmează a fi
depus. Odată cu adezivul pot fi pulverizate şi culori astfel
încât obiectele realizate să fie colorate.
Functionare - imprimare 3D
Imprimanta 3D depune pe o
suprafaţă de lucru straturi
succesive de pulbere. Fiecare
strat are o grosime de
aproximativ 0,1 mm.

Dupa imprimare
Modelul 3D
Obiectul 3D
este importat şi “aşezat”
pe suprafaţa de lucru cu
ajutorul software-ului
imprimantei
Obiectul final
in funcţie de destinaţia
obiectului final, acesta poate fi
impregant cu diverse substanţe
astfel încât să aibă durabilitatea
cerută.
Istoric
Scurt istoric al imprimării 3D
Într-un brevet, acesta a definit stereolitografia
ca ‘o metodă și aparat de fabricare a obiectelor
solide prin “imprimarea” succesivă de straturi
subțiri de material ce se întărește sub acțiunea
razelor ultraviolete, unul peste altul’.
Prin aceasta a stabilit baza pentru
ceea ce azi cunoaștem a fi fabricația
aditivă – sau imprimarea 3D.
Ziar american, 1987
RepRap
Proiectul RepRap
RepRap folosește o tehnică de fabricație
aditivă denumită Fused Filament
Fabrication (FFF) pentru a aplica materialul
în straturi: un filament de plastic este
derulat de pe bobină, topit și depus pentru
a fabrica o piesă.
În urma proiectului RepRap a
apărut prima imprimantă 3D tip
desktop.
