General information

What makes this dual-extrusion machine more reliable than others?

The Ultimaker 3 includes nozzle lifting technology and swappable print cores that are designed for specific ma- terials.These print cores have been intensively tested to provide maximum uptime with minimum maintenance. Currently two print cores are available: one for build materials and one for the PVA support material.This, in combination with the active leveling system and the use of geared feeders, results in a reliable printing process.

At what resolution does the Ultimaker 3 print

The Ultimaker 3 supports layer heights between 20 microns and 200 microns.

Does the Ultimaker 3 print faster than the Ultimaker 2+?

Single-extrusion prints may take slightly longer on the Ultimaker 3. Due to the fact that the print head of the Ultimaker 3 is heavier than the print head of the Ultimaker 2+, acceleration settings are lower to ensure optimal print quality. Dual-extrusion prints may take longer due to switching of the print cores and traveling to the switch bay.

What are the recommended operating conditions for the Ultimaker 3?

Ultimaker recommends an ambient operating temperature from 15 °C to 32 °C (59 °F to 89 °F) for the Ultimaker 3. However, printing with PVA on the Ultimaker 3 requires an ambient temperature below 28 °C and a relative humidity below 55%.

Print cores

What is a print core?

This is the name of the cartridge placed in the print head. The print core is the entire hot-end, with a chip built-in to communicate and sync with the printer.This chip contains information about the print core type and its runtime statistics.The design of the print core makes it easy to change, which increases the uptime of the Ultimaker 3. Currently there are two print cores available: one for all build materials (PLA, ABS, CPE, and Nylon) and one for PVA.

Why are two different print cores necessary?

Print cores are optimized for specific material properties. Based on the current set of materials, two print cores have been developed. As we extend materials, we will extend material specific print cores.

What is the nozzle size of the print cores?

The print cores have a nozzle with a diameter of 0.4 mm.

Why can’t the nozzle be changed to a different size?

The nozzle is integrated into the print core. We do not recommend disassembly of the print cores. They are fragile and assembled with specific force.

Can the Ultimaker 3 be used with only one print core installed?

No.The firmware for the Ultimaker 3 does not allow printing with only one print core installed. For single-extrusion prints, the second print core must still be in place.The reason to this is that the absence of the second print core will alter the airflow in the print head, which may impact the print quality.

Build plate leveling

Must the build plate be calibrated before using the printer for the first time?

No, this is done at our production facility. Also, active levelling is enabled to ensure a correct initial layer for the first print.

What is the recommended frequency for active leveling?

We recommend using the “Automatic” frequency.

What is the difference between active and manual leveling?

Active leveling uses the capacitive sensor in the print head.The user does not need to adjust the build plate.The build plate will not be positioned absolutely horizontal, but deviations are remembered.The position of the build plate at several points is stored in the printer.This data is used for Z-stage corrections during the first few layers of the print.

Manual leveling enables the user to change the height of the build plate at three locations by turning the knurled nuts. Use the calibration card while manually leveling for the most accurate results.
