FFSTD Doppia

The FFSTD Doppia is an FDM 3D printer from FFSTD with a 220 x 200 x 320 mm build volume.

Specifications

The FF-STD Doppia by the Latin American manufacturer Fused Form (a brand under ProtoLab 3D S.A.S.) is an industrial and semi-professional FDM/FFF 3D printer. It is engineered with a strict focus on reliability when operating with dual materials simultaneously. Its most prominent design feature is the integrated Doppia (dual) extruder setup, which allows printing complex geometries using soluble support filaments or multi-material assemblies.

• Extruder and Hotend Assembly

The machine is equipped with a dual-nozzle print head mounted on a single carriage. In the standard configuration, it utilizes two separate heater blocks and thermistors operating independently.

Calibration

Configuring a dual-extrusion system requires significantly higher precision than tuning a single-nozzle machine. Here are the eight crucial calibration procedures for the FF-STD Doppia:

• Mechanical Synchronization of Z-Axis Lead Screws

Before attempting bed leveling, you must ensure that the left and right sides of the X-gantry are at the exact same distance from the printer's base.

Common defects

Like many machines developed during the early semi-industrial FDM era, the FF-STD Doppia has specific hardware limitations and firmware quirks:

• Hardware defects and mechanical weaknesses
• Heat Creep and Hotend Jams: The cooling fans mounted on the hotend heat sinks are relatively small. During long PLA prints in warm rooms, thermal energy travels up the heatbreak. The filament softens prematurely in the cold zone, causing the extruder gears to grind and jam.

What it is used for

Best use-cases

• Industrial Prototyping with Soluble Supports: Thanks to the dual-extrusion system, the FF-STD Doppia is perfect for prints with complex internal chambers, overhangs, and moving parts. Using PLA as the model material and PVA (water-soluble) as support ensures outstanding surface quality above overhangs.
