In recent months, Aldi has repeatedly sold Bresser 3D printers.This will also be the case next week, when the T-REX with twin extruder will be available in the Aldi online shop.While the deals in the past have mostly had attractive prices, this is not the case this time.Those interested in a new 3D printer should avoid the Aldi offer.Because the Bresser 3D printer T-REX is currently much cheaper elsewhere.While the discounter is selling the device from next Thursday at 7 a.m. for 519 euros instead of the RRP of 849 euros, the T-REX is currently available from other online shops such as Amazon for only 449 euros.That's another 70 euros cheaper than Aldi - and thus the much better offer.However, it is unclear whether the Amazon price will still be valid next Thursday, which is why prospective buyers should rather strike promptly.The Bresser T-Rex is an interesting 3D printer and is built with the FlashForge Creator Pro 2 (about 750 euros at Amazon).The device is equipped with a twin extruder, so it can work with two colors at the same time.It is printed on an aluminum alloy and heatable printing platform, the maximum possible size is 227 x 148 x 150 mm.The printing accuracy is specified as 0.1 to 0.2 mm.Other features of the Bresser T-Rex include 10 mm guide rods for precise movement along the Z-axis, temperature control for different filaments, robust leveling adjustment screws, WLAN connectivity and a 3.5-inch display with touchscreen interface .In addition to the REXPrint slicing software and a 16 GB SD card, the scope of delivery also includes two filament spools, each with 1 kg PLA in black and white.
