Oqton’s MeltControl enabled by open APIs

JANUARY 21, 2026 | Reading time: 3 min

Oqton, a member of the EOS Developer Network (EDN), recently introduced MeltControl: a simulation-driven exposure strategy built using the EOS Toolpath API. It’s an exposure strategy developed by a 3rd party for EOS systems, marking a milestone for openness and the EDN.

What Is MeltControl from Oqton?

MeltControl is a new innovative exposure strategy in metal AM developed by Oqton. By combining physics-based process simulation with advanced scan path optimization, it adapts each scan vector to local thermal and geometric conditions - enabled by full vector access through the EOS Toolpath API. For manufacturers, this means greater design freedom and predictable results. MeltControl improves downskin quality, reduces material usage and post-processing, and replaces trial-and-error tuning with simulation-driven control - all without adding build time.

Key Benefits:

• Ultra-low overhang angles without compromising mechanical properties
• Fewer supports result is less material waste and post-processing efforts
• Superior downskin surfaces via physics-based micro waiting times
• No increase in build time despite improved part quality
• Together, these advantages show how simulation and open APIs redefine LPBF performance.

A Milestone for the EOS Developer Network (EDN)

With early access to the EOS Toolpath API and support from EOS experts, Oqton designed, validated, and launched MeltControl - proving how third-party developers can create custom process strategies for EOS machines.
