Printing Tips

Before Printing

Heat build plate as close to 85°C as possible. Using hairspray without lubricant (i.e., Aqua Net) is recommended.

Hyrel Setting Recommendations

The following settings are recommended for printing ABS on a Hyrel Printer:

MK1-250 Print Head Settings

ABS prints best from the MK1-250 print head with these settings:

  • Pulses per nanoliter: (leave default)
  • Flow Multiplier: 1.000
  • Prime Values:
    • Steps: 100
    • Rate: 10,000
    • Time: 25
    • Primes after tool change: 1
  • Unprime Values:
    • Steps: 100
    • Rate: 10,000
    • Time: 20
    • Unprimes before tool change: 1

Slic3r Settings

  • Printing Temperature: 235°C
  • Built Plate Temperature: 85°C
  • Cooling: 0% for first five layers; 50% thereafter

After Printing

Use progressively higher grit sandpapers to remove ridges from layers. Use heat gun to darken areas discolored by sanding. Apply finishing spray (XTC or similar) for a glossy finish.




Print in well ventilated conditions to avoid inhalation of potentially toxic fumes, although these are produced in relatively small amounts.

Avoid exposure to direct flame or temperatures greater than 404°C, as this could cause the ABS to catch fire.
