As it befits all Crossfield-class starships of the Federation Starfleet, USS Discovery was initially designated as a science vessel. However, following the outbreak of the Federation-Klingon War, the namesake ship of the Star Trek: Discovery series was re-classified as a warship under the command of Captain Gabriel Lorca. Distinguished by the experimental “spore” propulsion drive, the beautiful Discovery is able to jump from realm to realm and once even time-jumped 1000 years into the future!

Today, the Crossfield-class vessel from one of the most popular sci-fi television shows of all time joins Gambody’s catalogue of 3D printing starships! The USS Discovery model for 3D printing features a highly detailed saucer section that comprises three thin rings with elaborate patterns. The author of the model paid careful attention to the peculiarities of the starship’s construction in order to ensure the sophisticated design of the 3D printing saucer, secondary hull and the nacelles of the Discovery. 


USS Discovery for 3D printing is a static assembly model and its moderation and adaptation for different types of 3D printers took Gambody team 37 hours in total. The model’s cutting into assembly parts was made in such a way for you to receive the cleanest 3D printing result possible, to minimize the amount of filament needed for generated support and to ensure the seamless assembly of the spacecraft model.

All assembly parts are provided in STL files of the FFF/FDM version in recommended positions that were worked out to ensure the smoothness of the details’ surfaces after printing and that the 3D printing beginners won't face difficulties when placing the parts on a build plate. When downloading any model's file you will also receive "Assembly Manual" for FFF/FDM 1.0 and DLP/SLA/SLS 1.0 versions in PDF format. We highly recommend that you get acquainted with the “Assembly video” and "Assembly Manual" before getting down to the USS Discovery model.

The model is saved in STL files, a format supported by most 3D printers. All STL files for 3D printing have been checked in Netfabb and no errors were shown.

The model’s scale was calculated from the length of the original USS Discovery which is 750000 mm. The 3D printing model’s chosen scale is 1:1400 for the FFF/FDM version and 1:2800 for the DLP/SLA/SLS version.


FFF/FDM Smooth 1.0 + FFF/FDM Patterned 1.0 versions feature:
- Each version contains 24 parts;
- Both printed versions stand 127 mm tall, 218 mm wide, 535 mm deep;
- As prompt the titles, two versions differ in the level of detail on the ship's saucer;
- There are two variants of the upper hull - with or without ship’s name USS Discovery (NCC-1031);
- You can mount the ship on a special platform with Star Trek logo or conceal the designated slot with a cap;
- There are tunnels inside the ship for you to introduce LED wiring and light up the heart of the saucer and the nacelles; a spot to hide the battery is provided inside the secondary hull;
- All parts are divided in such a way that you will print them with the smallest number of support structures.

DLP/SLA/SLS Smooth 1.0 + DLP/SLA/SLS Patterned 1.0 versions feature:
- Each version contains 20 parts;
- Both printed versions stand 64 mm tall, 109 mm wide, 267 mm deep;
- As prompt the titles, two versions differ in the level of detail on the ship's saucer;
- There are two variants of the upper hull - with or without ship’s name USS Discovery (NCC-1031);
- You can mount the ship on a special platform with Star Trek logo or conceal the designated slot with a cap;
- There are tunnels inside the ship for you to introduce LED wiring and light up the heart of the saucer and the nacelles; a spot to hide the battery is provided inside the secondary hull;
- All parts are divided in such a way to fit the build plates and to ensure that support structures are generated where needed.

Below you can find printing recommendations for CuraSimplify3D and Slic3r software.

Cura printing recommendations:

These are basic settings that were tested in Cura 4.8.0 slicer. 

The test models were printed on Ultimaker 2, Creality Ender 3, Creality CR-10S Pro V2, Anycubic I3 Mega, Anycubic I3 MegaS 3D printers with PLA and PETG filaments.

Disclaimer: The following printing settings are a recommendation, not an obligation. The parameters can vary depending on the peculiarities of your 3D printer, the material you use and especially the particular assembly part at hand. Each part that any model comprises often needs preliminary review and you are free to tweak the settings the way you find suitable.

- You can scale up the model (downscaling is not recommended!);
- All connectors should be printed at 100% Infill;
- For all parts of locks (“ge_lock” in “Source files”) you need to change "Brim" type to "Skirt" in Build Plate Adhesion section.
