DEMU 3D Printer Mini review

159,99 inkl. Mwst.

The small price and proper features of the DEMU 3D printer Mini make the device stand out from other small print volume models. Also, the openness to materials is a big plus, considering that many competing products rely on proprietary filament.

For quite some time, a new 3D print­er made its way into the vast 3D print­ing world. The DEMU 3D Print­er Mini is sim­i­lar to devices like the M3D Micro or UP!Mini. Only dis­ad­van­tages are the less noble design (com­pared to the micro) and the few­er func­tion­al­i­ty (UP!Mini). In return, the 3D print­er offers a very low price which is around $200 at the time of our review.

Delivery content:

  • Plug n Play fin­ished 3D print­er
  • Print vol­ume of 110 x 110 x 125mm
  • 1 x PLA fil­a­ment coil
  • Pow­er Cable

Getting started

The DEMU 3D Print­er Mini does not need a detailed start-up descrip­tion because it is a very sim­ple plug-n-play machine (not a DIY kit). For some users, the only dif­fi­cul­ty seems to be cal­i­bra­tion of the print­ing plat­form, as there is no ful­ly auto­mat­ed solu­tion here.


The open fil­a­ment mount on the back of the 3D print­er makes it easy to use a wide range of spool sizes and thick­ness­es. The fil­a­ment spools are easy to attach to the hook and insert the mate­r­i­al through a noz­zle into the print­head.

The DEMU 3D Print­er Mini uses, in our opin­ion, the most suit­able fil­a­ment for small machines which is PLA. Com­pared to ABS, PLA curves much less due to the spe­cial mate­r­i­al fea­tures. Due to this dif­fer­ence in mate­ri­als, 3D print­ers gen­er­al­ly use heat­ed print­ing plat­forms for ABS that dri­ve up the cost of devices. There­fore, small 3D print­ers such as the DEMU 3D Print­er Mini pri­mar­i­ly work with PLA.

Despite the low­er mate­r­i­al cur­va­ture com­pared to ABS, dif­fi­cul­ties still arise depend­ing on the sit­u­a­tion. Espe­cial­ly a very cool envi­ron­ment and slight tem­per­a­ture fluc­tu­a­tions by e.g. wind lead to dis­tor­tions on the edges. In the worst case, this results in mis­prints that require a com­plete reprint. To pre­vent this, the con­tro­ver­sial sprays, so-called mouse ears and (our favorite) the blue tape help reduce this effect.


The DEMU 3D print­er Mini uses the slicer soft­ware “Cura” by Ulti­mak­er. The Cura soft­ware is a clas­sic and free slicer pro­gram for 3D print­ers. It allows var­i­ous types of oper­a­tions, func­tions and views of an object on a very sim­ple and user-friend­ly inter­face. Cura is per­fect for print­ing on small devices like the DEMU 3D Print­er Mini. If you still want a more pro­fes­sion­al or alter­na­tive slicers, you can look at the dif­fer­ent options on our slicer com­par­i­son chart.

The small price and prop­er fea­tures of the DEMU 3D print­er Mini make the device stand out from oth­er small print vol­ume mod­els. Also, the open­ness to mate­ri­als is a big plus, con­sid­er­ing that many com­pet­ing prod­ucts rely on pro­pri­etary fil­a­ment.

We can rec­om­mend this ful­ly assem­bled 3D print­er for an unbeat­able price of just under $200. It is per­fect for begin­ners and tech fans as an entry lev­el device or a gad­get for your home. The device is ide­al as a small gad­get for the home to meet your “geeky image” and to get to know the tech­nol­o­gy.

Have fun print­ing! 😉
