Rapid prototyping is a critical phase in every product development cycle. 3D printing turns a digital design into a physical model within hours, without the need for expensive moulds or the lengthy lead times of traditional manufacturing.
Whether you are developing a new product, testing the ergonomics of an enclosure, or verifying the fit of a mechanical assembly, FDM and SLA 3D printing enables fast iterations. Print a prototype, test it, adjust the CAD model, and print the next version — all in the same day. This dramatically shortens development cycles and reduces costs compared to CNC machining or injection-moulded prototypes.
For visual prototypes, we recommend SLA resin for a smooth, high-detail surface. For functional prototypes that must withstand mechanical loads, PETG or ABS are better choices. When maximum strength at minimum weight is required, carbon-fibre-reinforced filaments (PA6-CF, PAHT-CF) deliver industrial-grade performance.
Send3DSend is the only 3D printing service in Croatia with an instant online quoting tool. Upload your STL, 3MF, or STEP model to our calculator, choose your material and settings, and the price is calculated in seconds. No waiting for email quotes — order and pay online immediately.
Export your design as STL, 3MF, or STEP from your CAD software (Fusion 360, SolidWorks, Blender, Tinkercad, or other). Ensure the model is watertight and free of geometry errors.
Upload the file to our online calculator. Select the technology (FDM or SLA), material, layer height, and infill. The price and estimated print time appear instantly.
Confirm your order and pay online. Track the status in our system. Standard prototypes are usually ready the same or next business day.
Receive your prototype, test it, and adjust the design based on results. Repeat the process as many times as needed — each iteration costs only material and print time.
