Let's build something real

Open to research collaboration, fabrication projects, and conversations about making composite printing cheap enough to matter.

Workshop

Atoms, not just bits

Beyond the software: hundreds of hands-on engineering projects — repairing and remanufacturing functional parts for fun and for the challenge. A broken bracket becomes a CAD model, then a machined or printed replacement that outlives the original.

CNC · mill · lathe

Functional metal and plastic parts machined to fit — repairs, replacements, one-offs.

FDM & resin printing

Prototypes, game remakes, research specimens, end-use parts — PLA to CF-LDF feedstock.

Clay / paste extrusion

Delta WASP 40100 with custom parametric G-code — vessels designed in code.

CO2 laser cutting

Game boards, enclosures, engraved QR codes linking objects to their docs.

Electronics

Custom PCBs, firmware, sensors — synth keyboards to sailboat vision systems.

Education & Research · Current position

Long-fiber composites on machines everyone can afford

PhD candidate, Faculty of Mechanical Engineering, University of Ljubljana (2025–2028). My doctoral research tackles long discontinuous fiber (LDF) composites for FFF printing — getting a meaningful share of continuous-fiber performance out of standard hardware and CF/PLA feedstock, instead of the proprietary machines that dominate the field.

The economics are the point: LDF feedstock is 15–25× cheaper than commercial composite filament and up to 60× cheaper on the matrix side — turning composite printing from a per-part luxury into something you can run production on.

The work spans fiber preparation and wet sieving, filament compounding, large-nozzle extrusion (ø1.0–1.5 mm), critical fiber length modelling, and mechanical characterisation.
