    FAQWelcome to the FAQ section of OLA Manufacturing Platform! Here are some answers to frequently asked questions about our platform and the services we offer for the 4 industries we manage: 3D printing, Injection molding, CNC Machining, and Sheet metal fabrication.

    • What industries do you serve?

      We serve aerospace, automotive, healthcare, and consumer goods. Specialized in medical implants, lightweight aerospace brackets, and custom automotive tooling. 

    • Surface finishes / quality levels (EC, BC, FC): For which technologies do these apply?

      - EC (Economic): SLS/MJF – standard matte finish.  

      - BC (Business): SLA with manual polishing (±0.1mm).  

      - FC (First Class): SLM with mirror electroplating.  


    • What does surface finishing mean?

      OLA Surface finishing enhances aesthetics and functionality. Options include:  

      - Mechanical: Sanding, polishing.  

      - Chemical: Vapor smoothing, electroplating.  

      - Coatings: Paint, conductive layers.  


    • Do you support functional prototyping or end-use parts?

      Yes! (SLM/MJF) produces end-use parts like turbine blades  and automotive jigs. Prototypes use cost-efficient (SLS/PLA).  

    • What are the maximum/minimum part sizes?

      - Max: FGF (2m length), SLM (300x300x300mm).  

      - Min: SLA (0.2mm wall thickness). 


    • Can you print multi-material or color parts?

      Yes! MJF supports grayscale/color parts, and multi-material FDM combines plastics/rubbers.
