Hot Room & Materials

60°C in a controlled environment.
No warping. No compromises.

The Mille's heated chamber remains active throughout the entire printing process. On 1-meter-long parts, even a slight temperature fluctuation can cause critical warping. The Mille eliminates this risk at its source.

Active heated chamber
60°C
A stable thermal environment from start to finish. Essential for large parts with complex geometries.
Supported materials
PPS CF CF Nylon GF Nylon ASA CF TPU ESD-certified UL 94 V-0
Kentstrapper Mille Hot Chamber — 60°C test environment
Silicone thermal pad (120°C)
6 independent thermal pads distributed over a 1 m² surface area. Heat distribution across the entire print area up to 120°C.
Warping eliminated on large formats
The thermal gradients that cause warping in long parts are counteracted by the controlled thermal environment throughout the printing process.
Consistent scale reproduction
Consistent tolerances from the first to the hundredth print. Essential for production line setups and mass-produced fixtures.
Autocalibration via scanner sensor
Before each print, the scanner sensor detects the geometry of the entire printing bed surface and automatically compensates for it. No manual adjustments are required across the entire printing area.

Return on Investment

How much does "
" cost you every day without "
la Mille"?

Every large component you order from an outside supplier comes at a price: the supplier’s cost, weeks of waiting, and the lead time that halts production. The Mille isn’t an expense—it’s the end of those costs.

Contract manufacturer's cost (large piece, 3–5 kg) €600–2,000
In-house cost per thousand pieces €80–250
Lead time: from weeks to 24–72 hours
Estimated payback period 12–24 months

Domande frequenti — Stampante 3D Kentstrapper Mille

Cos'è la Mille e per quali settori è progettata?

La Mille è una stampante 3D FFF industriale con volume di stampa 1000×1000×1000 mm, il più grande disponibile in una stampante a filamento professionale Made in Italy. È progettata per l'industria pesante: automotive, nautica, aerospazio, meccanica industriale e difesa. Produce maschere di controllo, dime, stampi, fixture di linea e componenti strutturali.

Quali materiali si possono stampare con la Mille?

La Mille stampa PLA, PETG, ASA, ASA CF, ABS, TPU, Nylon GF, Nylon CF, PPS CF, materiali ESD e UL 94 V-0. L'estrusore Mantis ad alto flusso supporta ugelli da 0,4 a 1,4 mm con temperatura massima di 400°C. La camera riscaldata a 60°C e il piatto a 120°C garantiscono stabilità termica su tutta la superficie.

Perché la camera riscaldata è fondamentale su un volume da un metro?

Su pezzi da 800-1000 mm i gradienti termici tra la base e le zone alte generano tensioni interne che causano warping e deformazioni geometriche anche su materiali normalmente stabili. La camera riscaldata a 60°C mantiene un ambiente termico uniforme durante l'intera stampa. Senza camera riscaldata, pezzi di questa dimensione in Nylon CF o PPS CF sono difficilmente stampabili con tolleranze accettabili.

Qual è il risparmio economico rispetto al terzista o al CNC?

Il costo per pezzo con la Mille è di 80-250 euro, contro 600-2.000 euro per pezzo affidandosi a un terzista o a una lavorazione CNC. Il lead time si riduce da settimane a 24-72 ore. Con 4-8 pezzi grandi al mese, il ritorno sull'investimento si raggiunge in 12-24 mesi.

La Mille richiede un impianto elettrico dedicato?

Sì. La Mille richiede un'alimentazione trifase 380V, 18A, con 7.000W installati. Prima dell'installazione è necessario verificare la disponibilità di un punto di allacciamento trifase nel reparto. Kentstrapper supporta il cliente nella valutazione dei requisiti impiantistici in fase di prevendita.

Che tipo di assistenza è inclusa con la Mille?

La Mille include presa in carico del problema entro 4 ore e intervento on-site. Data la criticità dei sistemi di produzione industriale, l'assistenza avviene con tecnici che si recano presso il cliente. La configurazione è su misura per le esigenze specifiche dell'impianto.

La Mille è prodotta in Italia?

Sì. La Mille è progettata, costruita e testata a Firenze da Kentstrapper, produttore italiano di stampanti 3D professionali dal 2011. È la stampante 3D FFF industriale da un metro cubo di produzione italiana.
