Large 3D Printers

Intro

When printing on large 3D printers, thermal effects become more pronounced. Here is a study of issues for printing large objects successfully.

Analysis of Industry Standards

1. Airwolf Axiom 20 $10K - [1]
   1. 150C max temperature (lower than 178C continuous temp for OSE)
   2. 12 by 12 by 20"
   3. Internal heated chamber has 3 heat sources - Tri-heat
   4. internal chamber dries filament in 20 minutes
   5. Uses bed adhesive (consumable). Not state of art.

• Study of printing skateboards with Gigabot X - [3]

Cost

• Gigabot Exabot - 762mm x 762mm x 1,829mm = 37.5 cu ft [4]. Compared to OSE 4x4x8' printer - 128 cu ft. 3.4x larger.
• Gigabot - $9k for kit, $13k for machine - [5]
