OUR CAPABILITIES

Technical services

Professional CAD modeling for functional parts and mechanisms

We develop:
  • Parametric models (easily adaptable and modifiable)
  • Assembly models with moving parts and joints
  • Technical drawings with dimensions and tolerances
  • Exploded views for assembly instructions
  • We can ensure design suitability for CNC or sheet metal manufacturing
Analysis capabilities:
  • FEA (Finite Element Analysis)
  • Motion studies
  • Interference checks in assemblies
FDM 3D printing with multiple materials and post-processing

Available materials:
  • PLA – For prototypes and visual models, eco-friendly
  • PETG – For functional parts, good durability and flexibility
  • TPU – Flexible parts, seals, shock absorption
  • Other materials available on request (ABS, Nylon, composites)
  • We can also provide parts printed with other technologies (MJF, SLA, SLM, etc.) from our suppliers
Technical parameters:
  • Maximum part size: 256×256×256mm
  • Layer height from 0.08mm (high detail) to 0.3mm (faster)
  • Accuracy: typically ±0.2mm
  • Larger objects: can be split into parts with joints (glued, mechanical, hybrid)
Post-processing (on request):
  • Support removal and surface preparation
  • Sanding and polishing
  • Threaded insert installation
  • Painting and finishing
Experienced mechanical engineer’s perspective on every project – modeling with an engineering approach
  • Material selection consultation based on application
  • Tolerance and joint design
  • Strength calculations and FEA simulations
  • Design for Manufacturing and Design for Additive Manufacturing recommendations
  • Prototype testing and iterative improvement

APPLICATION AREAS

  • Functional Parts

    Spare parts for equipment, custom tools, assembly aids, fasteners, brackets

  • Mechanisms

    Articulated joints, linkages, moving models, educational mechanisms, demonstration devices

  • Product Prototypes

    Startup MVPs, product enclosures, ergonomics testing, design iterations, presentations

  • Manufacturing Support

    Jigs and fixtures, assembly aids, quality control tools, mold prototyping

  • Hobbies and Projects

    RC car components, robotics, custom devices, cosplay armor and props

  • Reverse Engineering

    Worn part restoration, measurements, obsolete part reproduction, upgrade solutions

FREQUENTLY ASKED QUESTIONS

  • Design project – 2 to 14 days depending on complexity
  • Print only – 2-5 days
Before we start, we always agree on a realistic timeline. For urgent cases, we can arrange a faster turnaround.
  • For design work – hourly rate starting at €20/hour or fixed price for simpler projects. Before starting project development, we’ll provide a price estimate with expected time.
  • For printing – use our price calculator below and find out the approximate price instantly. We’ll provide a specific quote within 24 hours.
All prices are explained when the invoice is sent.
For design projects:
  • 3D model files in your preferred format (STEP, STL, etc.)
  • Technical drawings (if requested)
  • Printed prototype (if requested)
All files are yours – you can use them for manufacturing, modify them, or order printing elsewhere.
For printing orders:
  • Printed part
  • Basic post-processing (support removal)
  • Other post-processing – on request
Our instant quote tool can currently only process STL, OBJ, or ZIP files.
We accept STL, OBJ, 3MF, STEP for manual quoting. We check every file before printing – if there are issues, we’ll contact you.
Work with confidentiality agreements is possible on request. All client projects are confidential by default and will only be used for our portfolio or marketing materials with client agreement.
We reprint parts free of charge if broken due to a defect.
One design iteration is included in design projects free of charge.
