Not all 3D printing services are the same, especially in the case of large size prototypes. This is where you separate boys from men.

3D printing is basically simple. A thin layer of polymer or liquid powder or melt is deposited by the nozzle onto the media where it cools and freezes or is cured by UV. Parts are constructed layer by layer by interpreting 3D CAD designs through software. Printer sizes range from small desktop models to create small objects in large engineering models to make complex prototypes.

As long as the prototype to be made is within the limits of the printer, there aren't many problems, although there are a number of things that should be considered. If the size is bigger than what the machine can print, it requires special expertise to collect large prototypes. This is where the difference lies when one chooses 3D printing services to create large objects with complex profiles.

Information Outsource’s printing and mailing services bureaus use the best and most sophisticated equipment to create complex prototype profiles with relative ease. The printer is paired with high-end software and handled by specialist engineers who are in the area of printers and software.

CAD designs for large prototypes that exceed the capabilities of the printer are divided into sections. Each part printed on a 3D printer modeling deposition merges using ABS or PC material in the form of a filament. It takes expertise to slice designs into pieces and then assemble them together using a unique welding process with liquid plastic to make large, smooth, monolithic, and structural sound sections. The finished part looks like it appeared from a large 3D printer.

Complicated profile prototypes may have holes, overhangs, niches, bridges and even threaded holes which must maintain dimensional tolerances after printing is complete. Any ABS or plastic tends to shrink on cooling and requires precise calculations to ensure the finished prototype has dimensions or holes that are dimensionally accurate. The experience, skills and knowledge of the staff handling the equipment at the large 3D printing service bureau is very meaningful.
