XYZprinting da Vinci Jr. Pro Xe+

The XYZprinting da Vinci Jr. Pro Xe+ is an FDM 3D printer from XYZprinting with a 175 x 175 x 175 mm build volume.

Specifications

The XYZprinting da Vinci Jr. Pro Xe+ represents an incremental yet strategically significant hardware iteration in the "Junior Pro" desktop FDM (Fused Deposition Modeling) printer lineup. Historically, XYZprinting products targeted schools and entry-level users with extremely locked ecosystems. The Xe+ variant builds upon the open-filament design principles of its predecessor, the Pro X+, providing minor mechanical tweaks, updated mainboard revision, improved component cooling pathways, and expanded compatibility with engineering-grade materials within a compact, fully enclosed envelope.

Calibration

Achieving consistent, high-precision results on the da Vinci Jr. Pro Xe+ requires systematic calibration of the mechanical and thermal subsystems. Follow these 8 detailed steps:

• De-greasing and Chemical Preparation of the Bed

Clean the glass surface thoroughly before starting a print. Spray a generous amount of 99% Isopropyl Alcohol (IPA) on the cold glass plate and wipe it down using a lint-free microfiber cloth.

Common defects

• Hardware defects and mechanical weaknesses
• Extruder Arm Cracking: The plastic tension arm on the Bowden feeder assembly is prone to developing hairline cracks under constant spring pressure. This reduces tension on the feed gear, causing filament slippage.
• Symptom: Under-extrusion, motor clicking, and thin, weak print walls.
• Solution: Replace the plastic extruder housing with an all-metal dual-gear extruder upgrade.

What it is used for

Optimal Scenarios

• Schools and Educational Labs: The fully enclosed chamber, mechanical safety switches, and quiet operation (<50 dB) make it ideal for classroom environments.
• Detailed PLA Prototyping: Ideal for printing architectural models, toy prototypes, and visual maquettes with clean surface finishes.
