FAQ Using the printer • What is the maximum size of the object that can be printed? Workspace of MendelMaxPRO 3D printer is 20 x 20 x 16 cm (L x W x H). Object could be positioned at the build table diagonally, so the maximal length of the object that can be printed in one piece is approx. 28 cm. When printing large objects it is necessary to follow certain rules. • Which software MendelMaxPRO uses? MendelMaxPRO is using the Marlin firmware. For preparing 3D model for print we suggest Slic3r and for printer control Pronterface. All software is open source and we are delivering it with the printer. • Which file formats of 3D models are supported? Model to be printed should be in STL format. Export to STL is available in majority of the 3D design applications. • I have problems with printing long (12 cm) narrow object in ABS, it warps and unsticks from the table. All materials used for 3D printing shrink when cooling, which is especially the case for ABS. When printing long objects, having significant height (>1-2 cm), cooling (and shrinking) of top layers produce tension, which causes deformations. By following a few simple rules, you can prevent that undesirable effect: - Check the calibration of the build plate. If it is not leveled, at points where print head is more distant from the plate, object will be weakly bound to the substrate, - Clean the build plate. Traces of grease weaken adhesion. Surface of the build plate covered with Kapton tape can be cleaned with alcohol, acetone, and nitro diluter. - Turn on the brim option in slicing program. Additional surface will increase adhesion. - When printing ABS turn the fan off. For small objects rather decrease the printing speed or print multiple objects together to allow cooling. Filaments • What types of filaments could be used for your 3D printer? PLA, ABS or both? MendelMaxPRO is using 3mm filaments. It can use any material intended for 3D printing, e.g. ABS, PLA, Polystyrene, PET, Nylon, Bendlay, LAYWOO-D3 wood filament, Sandstone LAYBRICK. Please check our offer of filaments! 3D design • How can I get the 3D models to print? If you have specific requirements please let us know and we will offer you the design of the object you need. At the Thingiverse site you can find large number of 3D objects ready to be printed. • How can I export 3D file from AutoCAD 2010 to STL? - Click on Output tab->Send panel->Export. - Enter the file name into the Export Data form. - At Files of Type choose Lithography (*.stl). Click on Save. - Select one or more objects. All objects have to be within the positive XYZ octant of the global coordinate system (WCS), i.e. X, Y, and Z coordinats should be positive. - STL extension will be automatically added to the file name. Ordering • Which is the delivery time for the MendelMaxPRO kit? Delivery time is 10 working days.

Podrška korisnicima Upotreba pisača • Koliko veliki predmet je moguće ispisati? Radni prostor MendelMaxPRO 3D pisača je 20 x 20 x 16 cm (d x š x v). Predmet je na radni stol moguće postaviti dijagonalno, tako da je najveća duljina predmeta kojeg je moguće ispisati u jednom komadu cca. 28 cm. Kod ispisa većih objekata potrebno je poštivati određena pravila. • Koji softver koristi MendelMaxPRO? MendelMaxPRO koristi Marlin firmware (upravljački softver pisača). Za pripremu 3D modela za ispis predlažemo Slic3r, a za kontrolu rada pisača program Pronterface. Svi programi su open source, a isporučujemo ih uz pisač. • Koji formati 3D datoteka su podržani? Model koji želite ispisati treba biti u STL formatu. Eksport 3d modela u STL podržavaju praktički svi programi za 3D dizajn. • Imam teškoća s ispisom dugačkog (12 cm) uskog predmeta u ABS-u, na krajevima se odlijepi od podloge. Svi materijali koji se koriste za 3D ispis hlađenjem se u određenoj mjeri stežu, što je posebno izraženo kod ABS-a. Kod ispisa dugačkih objekata značajne visine (>1-2 cm) hlađenje (stezanje) gornjih slojeva stvara napetost koja uzrokuje deformaciju objekta. Poštivanjem nekoliko jednostavnih pravila možete spriječiti navedeni efekt: - Provjerite kalibraciju radnog stola. Ako stol nije ravan, na mjestima gdje je glava pisača više udaljena od stola predmet će biti slabo vezan za podlogu i podložan odvajanju, - Očistite radni stol. Tragovi masnoće oslabiti će prijanjanje predmeta na podlogu. Površinu radnog stola prekrivenog Kapton trakom možete očistiti alkoholom, acetonom, a veće nečistoće nitro razređivačem. - Koristite opciju generiranja oboda (brim) oko predmeta. Dodana površina pojačati će prijanjanje predmeta. - Kod ispisa ABS-om obavezno isključite ventilator. Materijali • Koju vrstu materijala vaš 3D pisač koristi? PLA, ABS ili oboje? MendelMaxPRO koristi nit promjera 3mm. Raspoloživ je niz materijala: ABS, PLA, najlon, drvo, kamen i dr. Pogledajte našu ponudu materijala! 3D dizajn • Kako mogu doći do gotovih 3D modela. Ako imate specifične zahtjeve, javite nam se pa ćemo Vam ponuditi dizajn predmeta prema Vašim zahtjevima. Velik broj različitih predmeta spremnih za ispis možete naći na Thingiverse stranici • Kako mogu eksportirati 3D datoteku iz Autocada 2010?. - Kliknite na Output tab->Send panel->Export. - U Export Data formi unesite ime datoteke. - Pod Files of Type, odaberite Lithography (*.stl). Kliknite na Save. - Odaberite jedan ili više objekata. Svi objekti moraju biti unutar pozitivnog XYZ oktanta globalnog koordinatnog sustava (WCS), tj. X, Y, and Z koordinate moraju biti veće od nule. - Ekstenzija .stl biti će automatski dodana imenu datoteke. Naručivanje • Koje je trenutno vrijeme isporuke za MendelMaxPRO u dijelovima? Vrijeme isporukle pisača u dijelovima je 10 radnih dana.
