Kentstrapper Mavis — Large-format 3D printer (400x400x700mm)
01

Large Format

700 mm high.
Consistent quality across the entire range.

The Mavis is designed with an architecture optimized for vertical printing: structural stability and motion control even during extended print runs. Tall prints are no longer a problem to manage—they’re a process to integrate.

Print volume
400 × 400 ×
× 700 mm
Cartesian. Optimized structural stability for long-lasting vertical prints. Consistent quality from the first to the last millimeter.
Cartesian Architecture for Verticality
The structure is optimized to maintain control of movement along the entire Z-axis. The Cartesian kinematics ensure consistent deposition geometry from the first to the last centimeter of the part.
Extended print runs
Process stability for long-run machining. Dimensional prototypes, design elements, structural components: reliable and repeatable production.
1 or 2 extruders
Standard single-extruder configuration. Optional dual-extruder setup for two-color prints or prints using dedicated support material.
700 mm in height. For tall components that won't fit anywhere else, the Mavis is the only indoor option.

S.E.M.

Continuous production.
Maintenance no longer stops the line.

Kentstrapper’s Magnetic Extrusion System addresses the main hidden cost of industrial 3D printing: downtime caused by head changes. On a Mavis that prints tall components for hours on end, every minute counts.

Replacing the S.E.M. print head
<30 sec
Disconnect the two connectors and release the magnetic latch. No tools required.
Standard
PLA, PETG, ASA, ABS — high-quality surface finish
Technique
GF Nylon, CF Nylon — mechanical and thermal resistance
High Flow
Thick layers, large parts — faster production
S.E.M. Kentstrapper Head — Quick-Change Magnetic System
S.E.M. in action
Change the print head in less than 30 seconds. No tools required, no production downtime.

Reliability

Three protective covers for unattended "
" prints.

Self-calibrating print bed, filament flow sensor, automatic restart after a power outage. On print jobs that last for hours, every safety feature counts.

Self-calibrating plate
Full or partial self-calibration of the print area before each job. Removable, flexible build plate for easy part removal.
Filament sensor — automatic pause
The printer has a built-in sensor that not only detects the presence of the filament but also monitors its feed. If the filament runs out or the feed becomes irregular, the printer automatically pauses. No parts are lost due to filament depletion or feed issues. The internal spool holder also helps dry the filament partially during printing.
Restart after the blackout
Built-in sensor that ensures printing resumes when power is restored. For jobs that take several hours, no parts are lost due to a power outage.
Silicone thermal pad rated for 120°C
Fiber-reinforced surface for engineering plastics. Temperature up to 120°C for stable adhesion across the entire 400×400 mm base.

Manufacture indoors or outdoors

The actual cost of shipping
is higher for each component.

Parts taller than 350 mm won’t fit in a standard 3D printer. Until now, the only option was to outsource—which meant delays, high costs, and reliance on others. Mavis solves this problem in-house.

Domande frequenti — Stampante 3D Kentstrapper Mavis

Cos'è la Mavis e per quali applicazioni è indicata?

La Mavis è una stampante 3D FFF ad alta velocità con volume 400×400×700 mm e sistema S.E.M. (Sistema di Estrusione Magnetico) per il cambio rapido delle testine in meno di 30 secondi. È indicata per prototipazione rapida, produzione in ortopedia e ausili personalizzati, design industriale e museale, e produzione di grandi modelli in scala reale.

Quali materiali supporta la Mavis?

La Mavis stampa PLA, PETG, ABS, ASA, Nylon, Carbon PETG e Carbon PLA in configurazione standard, e materiali flessibili con la testina adatta. Il sistema S.E.M. comprende testine Standard, Tecnica e Alto Flusso con ugelli fino a 1,8 mm e altezze strato fino a 2 mm. Il piatto è magnetico in PEI.

Quali sono le prestazioni di velocità della Mavis?

La Mavis raggiunge 400 mm/s di velocità di stampa con accelerazioni fino a 10.000 mm²/s. Integra un accelerometro per la compensazione delle vibrazioni a velocità elevata. Il sistema S.E.M. consente il cambio testina in meno di 30 secondi, eliminando i tempi morti tra produzioni con materiali diversi.

La Mavis è adatta all'ortopedia e al design?

Sì. Il volume 400×400×700 mm consente di stampare busti ortopedici, corsetti e ausili personalizzati in un unico pezzo senza giunzioni. Nel design industriale e museale, il formato permette prototipi in scala reale e modelli fisici di grandi dimensioni. La riduzione dei tempi rispetto ai metodi tradizionali è stimata nel 50-60%.

La Mavis richiede un operatore dedicato?

No. La Mavis è dotata di sensore encoder antiblocco filamento, ripresa automatica da interruzione di corrente e gestione remota via Wi-Fi e LAN. Non è necessario un operatore dedicato per il monitoraggio continuativo.

La Mavis è ammissibile alle agevolazioni Industria 4.0 / Transizione 5.0?

Sì. La Mavis è certificata CE e dispone di connettività Wi-Fi e LAN per l'interconnessione al sistema informativo aziendale, requisito previsto dalla normativa Industria 4.0 e Transizione 5.0. È disponibile in leasing operativo, compatibile con le agevolazioni fiscali in vigore.

La Mavis è prodotta in Italia?

Sì. La Mavis è progettata, assemblata e testata a Firenze. Kentstrapper produce stampanti 3D professionali a Firenze dal 2011. Il supporto tecnico è diretto, senza intermediari.
