Tiertime also offers a heated bed option (up to 100 degrees centigrade) and soon a steel nozzle upgrade. The Cetus supports PLA primarily but is also compatible with PET, PETG, TPU, TPE, PVA, and Wood-filled material. It’s designed for easy removal of prints while holding them securely in place while the printer is working away and negates the need for painter’s tape, hairspray, glue or your adhesive of choice. The surface is a textured, adhesive layer that sticks to PLA and similar materials. The coating recipe is a well-kept secret on Tiertime’s part. The non-heated print bed consists of 3 mm of aluminum fixed directly onto the Y-axis linear rail with a unique nozzle height error tolerant coating designed to secure the first layer of the print model to the bed. The combination of nozzle diameters and resolutions mean the Cetus is versatile enough to manage both detail-oriented final product printing and quickly-rendered prototypes or draft pieces. The compact single extruder is of the direct drive variety with interchangeable PEEK-made nozzles with diameters of 0.2 mm, 0.4 mm, and 0.6 mm with layer resolutions of 50, 70, 100, 200, 250, 300, and 350 microns. Belted stepper motors assure movement on the axis. The linear rails on each axis ensure quiet, precise functionality with the extruder rail controlling the X-axis, while the print bed runs on the Y-axis, and finally, the extruder rail moves along the Z-axis module. It uses Melted Extrusion Modeling (MEM) print tech with a cantilever design. The build volume is a modest 180mm x 180mm x 180mm that relative to the size and weight (12.1 lbs) of the printer is an amazing ratio. The chassis is constructed with high-quality aluminum extrusions that coupled with the linear rail axis modules, and the low-profile rubber footed mainboard, keep the model upright with a non-chambered, guts exposed, minimalist feel that belies an impressive rigidity. The minimalist, open-ended functionality also extends to modding as the Cetus is ripe for tinkering and add-ons. It’s small and lightweight, but remarkably sturdy while the small footprint and portability mean it is easily transported from home to office or wherever else it might be needed with minimal hassle. Combined they create a small form factor printer without any redundant, frivolous additions nor bells and whistles. The Cetus is a minimalist printer whose driving force springs forth from Tiertime’s desire to manufacture a 3D printer free of the complexity that unfortunately defines various models on the market with an emphasis on enjoyment and functionality.Ī quick look at the Cetus reveals a simple, yet intelligent design based on six core modular components: three-axis modules, a main board electronic module, a print bed, and an extruder.
