Extra Large Format 3DBenchy Print Timelapse Overview Video

We are here to talk today about Benchy as coined by CT3D. 3DBenchy is a standard design that offers a large array of challenging geometrical features for 3D printers. The different surfaces of the #3DBenchy model reveal common issues regarding surface finish, model accuracy, warping, etc. A typical Benchy for a normal industrial printer is relatively small, but we have a really large format printer, so we had to scale this up just a bit.

We also did a post on reddit with the banana and nobody believed that it was real. We are here to prove that it is real, and also talk about the capabilities of our large format 3D printer. We also printed some very tiny ones and we posted them here just for scale size.

Watch how 3D Platform goes beyond big creating an Extra Large Format 3DBenchy on the Workbench 400 Series 3D printer.

It printed in about 48 hours and weighs 38 pounds. It used 7.5 spools of filament extruded through a 2-millimeter nozzle.  The throughput speed was 32 millimeters per second with a 1-millimeter layer height.

This new benchy printed by 3D Platform goes beyond large format printing! This HUGE 3DBenchy was printed on 3D Platform’s 400 series machine with a HFE300. It was printed out of PLA with a 2mm nozzle, 1mm layer height, 10% infill, 3 bottom layers, 6 top layers, 1 perimeter, and a print speed of 32mm/s.


The print took 7 and a half spools to complete. Each color change is one complete spool. The engineers went through one full spool in about 7 hours. Altogether, this sizable benchy took about 48 hours of total print time. The print weighs in at about 38lb or 17.24KG.

The only problem area the team encountered was the overhangs. This is a common issue when printing benchys, especially with large format. So, for something in such an EXTRA large format, the engineers had to watch closely to not let the overhang issue derail the entire print process. To avoid print failure due to the overhangs and bridging, they use more cooling to utilize the settings in Simplify3D and adjust the bridge/overhang speed as well as extrusion multiplier.  In the pink area you can see some gaps in the perimeter due to the pink filament being an older spool, but it was nothing that really stands out to the naked eye. It’s always best to print with fresh filament!
