    01Projects

    Ten projects that run today. Eight of them are live websites. You can open each one.

    Parametric G-code · Clay printing

    Clay Studio

    Design a clay vessel in the browser. The app writes G-code for the Delta WASP 40100 printer.

    Tangible instrument · Computer vision

    TileGroove

    Put printed tiles on glass. A phone camera reads them. The tiles play music loops in time.

    Augmented reality · Print preview

    ScalePrint AR

    Look at an STL file at true size on your desk. Check the size before you start a long print.

    Rules archive · QR linked

    Board Game Rules

    Rules for 24 board games in Slovenian and English. Each game I make carries a QR code to its page.

    3D game · Three.js

    Nightona US&A

    An arcade car racer in the browser. The track, the banking and the AI drivers are all generated.

    Automated pipeline · Daily

    Ljubljana Bulletin

    A daily page for tourists. The pipeline collects events and weather, then publishes without help.

    Tool collection · Eight apps

    DK Lab

    Eight browser tools. They include a sensor kit, chess over WebRTC and two language aids.

    Quiz platform · Static

    Triviador

    A quiz platform. It runs a full pub quiz from static files, so hosting costs nothing.

    Hardware synth · PCB and firmware

    XIANO

    A synthesizer on a Seeed XIAO board. I made the capacitive keyboard PCB, the firmware and the case.

    Computer vision · Safety aid

    Marine Aid

    An obstacle alarm for an 11 m sailboat. A Raspberry Pi watches the sea with one camera.

    02Research and education

    PhD candidate, Faculty of Mechanical Engineering, University of Ljubljana. 2025 to 2028.

    My subject is long discontinuous fiber (LDF) composites for FFF printing. Standard printers must make strong composite parts. Today this needs proprietary machines.

    Cost is the reason for the work. LDF feedstock costs 15 to 25 times less than commercial composite filament. The matrix costs up to 60 times less. At this price you can run large test series, and later real production.

    The work includes fiber preparation, wet sieving, filament compounding, large nozzle extrusion, critical fiber length models and mechanical tests.

    03Workshop

    I repair and remanufacture functional parts. There are hundreds of these projects. A broken part becomes a CAD model. Then I machine it or print it. The new part usually outlives the old one.

    8LIVE SITES

    CNC, mill and lathe

    Metal and plastic parts, machined to fit. Repairs, replacements and one-off tools.

    FDM and resin printing

    Prototypes, game parts, test specimens and end use parts. From stock PLA to CF composite feedstock.

    Clay and paste extrusion

    Work on the Delta WASP 40100. The toolpath comes from my own parametric G-code, not from a slicer.

    CO2 laser cutting

    Game boards, enclosures and engraved QR codes. The code links the object to its documentation.

    Electronics

    Custom PCBs, firmware and sensors. Examples: a capacitive synth keyboard and a boat vision system.
