STAMPA 3D TECNOLOGIA FDM
WORKSHOP

La stereolitografia è una
tecnica che permette di
realizzare singoli oggetti
tridimensionali a partire
direttamente da dati digitali
elaborati da
un software CAD/CAM

COSA SONO LE STAMPANTI 3D
Macchine in grado
di produrre
un oggetto fisco
partendo da un
suo modello
tridimensionale
La manifattura
additiva è una
tecnologia di
processo dove
le parti sono
create per strati
depositati in
successione
La ‘Fused Deposition Modeling’ (letteralmente: modellazione a
deposizione fusa) FDM, è una tecnica additiva in cui ogni strato è
formato da un “percorso” di materiale polimerico fuso, depositato da un
ugello riscaldato

3 DIFFERENTI TIPOLOGIE DI STAMPANTI
A deposito additivo di materiale, generalmente
plastico, termo fuso
(FDM o FFF)
A solidificazione di blocchi di resina, o di un
polimero liquido fotosensibile
attraverso l’uso di un fascio di luce UV
(SLA o DLP)
A sinterizzazioni mediante l’uso di polveri
agglomerate attraverso l’uso di un laser
(SLS, SLM, EBM)
FDM
Nella Modellazione a deposizione
fusa un filamento 
a) Bobbina di materiale plastico è spinto
verso una testina mobile riscaldata 
b) che fonde ed estrude il filamento
depositandolo, strato dopo strato, nella
forma desiderata 
c). Oggetto
d) per sorreggere le parti sporgenti.
e) Una piattaforma mobile 
si sposta dopo che ogni strato è stato
depositato. Per questo tipo di
tecnologia di stampa è necessario
aggiungere al modello delle strutture
temporanee di sostegno verticali 
SLA
Nella modellazione a
solidificazione di blocchi di
resina, o di un polimero
liquido fotosensibile
a) Fascio di luce AV 
b) Cassetto con liquido 
c). Oggetto 
e) Una piattaforma mobile 
si sposta dopo che ogni
strato è stato depositato
SLS
A sinterizzazioni
mediante l’uso di
polveri agglomerate
attraverso l’uso di un
laser
