3D printing, also known as additive manufacturing, involves building 3D objects from a digital file by laying down successive layers of material. The first 3D printer was developed in 1984 and printed objects by depositing layers of liquid, powder, or sheet material and fusing them together. Today, 3D printing technologies include fused deposition modeling (FDM), selective laser sintering (SLS), stereolithography (SLA), and binder jetting. 3D printing has applications across industries like manufacturing, engineering, healthcare, and education.

Il valore delle storie nei processi di design centrati sull'utenteManuele Forcucci
Le storie sono il mezzo attraverso le qual, da sempre, condividiamo informazioni, forgiamo scenari, risolviamo problemi.
Fare user research e ascoltare le storie delle persone, diventa perciò sempre più fondamentale per comprendere contesti, situazioni, problemi che possono essere tradotti in soluzioni di design. Le storie sono uno strumento molto potente nei processi di design centrati sull’utente poiché riescono a connettere i bisogni ai processi stess
Un tentativo di sistematizzare il processo lavorativo di nois3 e una proposta che mostra, assieme ad alcuni casi di studio, come la qualità del lavoro e la soddisfazione del team siano cresciuti.
Una lista di cose se volete banali, ma messe in fila.
Ogni volta che una nuova tecnologia viene introdotta nella società, ci deve essere il contrappeso di una spinta umana che ristabilisce l'equilibrio – cioè high touch – se no la tecnologia viene respinta. Più c'è high tech, più occorre high touch.

Una nuova frontiera che all'inizio sembrava interessare di più il segmento consumer, ma che è destinata a cambiare i processi produttivi anche nelle aziende manifatturiere
Office Automation
gennaio 2014
Oggi è in corso una terza rivoluzione che sta portando alla digitalizzazione dei metodi produttivi. Grazie alla fabbricazione additiva, un prodotto può essere progettato su un computer e dopo pochissimo tempo essere realizzato con l’impiego di un processo tecnologico che crea un oggetto solido attraverso la sovrapposizione di diversi strati di materiale uno sull’altro. Il processo può essere portato avanti in maniera del tutto automatica, senza che vi sia un operatore a tenere sotto controllo la macchina, e la nuova tecnologia di produzione consente di creare prodotti anche molto elaborati che non potrebbero essere costruiti con i tradizionali sistemi di produzione.
La stampa 3D è una rivoluzione che va prima di tutto capita per calarla al meglio nella propria realtà. I criteri e i parametri a cui far riferimento per scegliere la stampante 3D più adatta all’esigenze della propria azienda.

Laser Melting
12. SLS – Selective Laser Sintering
Questa stampante utilizza un
sistema di polveri
termoplastiche e realizza
oggetti tridimensionali
sinterizzando e fondendo un
sottile strato di polvere
polimerica alla volta. Questo
procedimento consente di
realizzare oggetti di piccole
dimensioni con una
grande definizione e con una
grande resistenza.
13. SLS – Selective Laser Sintering
PREZZO: a partire da 20.000€
COSTO MATERIALE 100-200€ al kg
Area di Stampa 10 x 10 x 13 cm.
14. SLM – Selective Laser Melting
Questa tecnica non utilizza la
sinterizzazione per la
solidificazione dei granuli di
polvere, ma fonde totalmente il
materiale in modo selettivo,
utilizzando un laser ad alta
energia.
Con questa tecnica le proprietà
meccaniche e fisiche
dell’oggetto sono praticamente
identiche a quelle di un modello
ottenuto per fusione tradizionale,
senza le criticità (es. fragilità)
tipiche dei materiali
sinterizzati.
15. SLM – Selective Laser Melting
Area di stampa: 125mm x 125mm x 200mm
leghe di titanio
leghe di cromo-cobalto
accaio inossidabile
alluminio.
PREZZO: 250.000€
16. POLYJET
La tecnologia a getto
di inchiostro PolyJet,
brevettata da Objet,
funziona emettendo
getti di materiali
fotopolimerici
innovativi in strati ultra
sottili (16µ) su un
vassoio di costruzione
fino al completamento
del componente.
17. OBJET 1000 – Tecnologia Polyjet
Area di lavoro 1 × 0,8 × 0,5 m.
Prezzo Stampante intorno ai 550.000€
Costo materiali 36.000 €
18. DLP - Digital Light Processing
Esponendo alla luce di un proiettore
DLP un polimero liquido posto in una
vasca che si indurisce strato dopo
strato. Imprimendo i singoli pixel, una
stampante 3D con tecnologia DLP
può realizzare prototipi ad alta
risoluzione.
19. DLP - Digital Light Processing
Area di stampa: 114x110x170 mm
Precisione 70 micron
Costo Stampante 3.500€
Costo Materiali 135€/litro
20. SLA – Stereo Lithography
All'interno della macchina
sono presenti un laser, una
vasca con la resina da
solidificare
Il laser solidifica la resina in
funzione della sezione del
pezzo da realizzare, si
abbassa la piattaforma sulla
quale é vincolato in pezzo in
costruzione e si riparte con
una successiva sezione da
solidificare.
Questo procedimento viene ripetuto fino a pezzo ultimato.
Successivamente vengono rimossi i supporti necessari affinché il pezzo non
crolli in fase di lavorazione; come ultima fase, i particolari, vengono posti in
un forno UV che garantisce la totale solidificazione della resina.
21. SLA – Stereo Lithography
Area di stampa:
145×145×175mm
Precisione 25 micron
Costo Stampante 3.300€
Costo Materiali 135€/litro
23. OPPORTUNITA’
• Può essere considerata una tecnologia di supporto alla classica
iniezione plastica permettendo, a fianco della produzione di grandi
numeri di prodotti, la realizzazione anche di piccole serie o di prodotti
personalizzati
• Possiamo trovare ambiti di investimento per differenziare la tipologia dei
prodotti forniti in termini di numeri e materiali mantenendo però la stessa
connotazione di conto terzisti
.
• Perché le stampanti 3D permettono
la realizzazione di geometrie
estremamente complesse che
possono essere rappresentate
matematicamente, ma che non
possono essere ottenute con gli
approcci convenzionali
24. OPPORTUNITA’
• Maggiore flessibilità e velocità di reazione nella fase di preventivazione
• Poter toccare con mano ciò che si sta solamente concettualizzando con
un modello 3D permette in fase preventiva di poter evitare problematiche
quindi introdurre innovazioni o miglioramenti
• Poter condividere con clienti e fornitori campioni estetici di prodotti più o
meno complessi, oggetto di successiva industrializzazione
• Nel complesso, la stampa 3D è un’ottima soluzione per avere il pezzo
finito disponibile per prove e valutazioni, prima di effettuare investimenti e
progetti provvisori.
25. LIMITI
• Utilizzo funzionale dei prototipi. Attenzione quindi se vi aspettate
caratteristiche meccaniche simili ai tecnopolimeri di stampaggio.
• E’ anche vero che molte volte il materiale stampato ha caratteristiche
superiori a quello che occorre per lo scopo preciso di quel pezzo, e quindi
lo si può realizzare tranquillamente con le tecniche additive in piccoli lotti.
• L’unica tecnica di prototipazione additiva che consente un utilizzo strutturale
del prototipo rimane la SLM
• Costi elevati
• Possibilità di creare condotti di raffreddamento impensabili con
tecnologie tradizionali, migliorando quindi il condizionamento dei maschi
• Costi elevati per acquistare macchine professionali
