Techniques

• Designing for Printing Part 1: Unit Tests and Tolerances
• Designing for 3D printing Part 3: Decreasing Print time - orientation, limiting overhands, splitting parts
• Embedding components in Markforged printed parts
• Adhering co-part assemblies
• Bonding Markforged Plastic Parts to Other Materials

Adhesives for bonding Onyx parts

• Loctite 401 (Onyx to Onyx)
• Scotch-Weld DP100 (for bonding Onyx to other materials - source)
• Scotch-Weld DP100Plus
• Scotch-Weld DP420

Humidity Protection

Monitoring

For monitoring humidiy of the plastic to ensure good extrusion. Humidity causes extruder clogs.

• Humidity monitor and alarm
• Hygrometer (cheap and simple)

Storage

• Pelican Air cases - watertight
• Pelican Vault cases - "weather resistant"

Maintenance

The Maintenance Schedule Utility tracks consumable lifetimes and notifies you when components are due for maintenance or replacement. Replacing consumables is simple. The printer itself gets a step-by-step instructions and the guides are available in the Markforged Support Portal.

Consumables:

• plastic nozzle
• plastic Bowden tube
• plastic feed tube
• fiber nozzle
• fiber Bowden tube
• fiber feed tube

Calibrations:

• Belt tension (82Hz–85Hz when plucked, measured using a frequency tuner app like PanoTuner Lite)
• XY calibration (performed with a reference bed)

Third Party Materials

• Obsidian PA6+Carbon Fiber - a third party nylon-carbon fiber composite filament.
