3D-print enthusiasts who appetite to try SLA press at low amount may be tempted by the MP Mini Deluxe. But be able to advance some time in accepting it running.
Resin 3D press acclimated to be the bottle of the affluent and well-resourced. This blazon of 3D printer uses a photopolymer-resin press material, which solidifies aback apparent to ultraviolet light, a action alleged stereolithography (SLA). This book offers bigger capacity than the melted-filament access of alloyed degradation accomplishment (FDM) printers like the LulzBot Mini 2.
Because SLA press is a rather circuitous action generally involving lasers and absolute mechanics, the printers were actual adult and expensive. Or, at least, they acclimated to be: Now, printers like the $599 MP Mini Deluxe are bringing this action to the home user.
You’ll accomplish some trade-offs in accepting the lower price, though. The press action is still circuitous and messy, and the MP Mini Deluxe has some austere shortcomings that could put off all but the best committed users.
The MP Mini Deluxe costs so little partly because it takes a altered access than added SLA printers. More-expensive models, like the Peopoly Moai or the Anatomy 2 use an ultraviolet (UV) laser, which bounces off affective mirrors into the cellophane basal of a vat of adhesive to anatomy the print. The MP Mini Deluxe replaces the laser and mirrors with UV LEDs and an LCD awning beneath the basal of the book tray.
Credit: MonopriceThis LCD awning selectively lets the UV ablaze through. If the awning is clear, it lets the ablaze through and the adhesive solidifies. If the awning is opaque, it blocks the UV and the adhesive stays liquid. The printer lowers the book bed into the resin, creating a attenuate band that is apparent to the light. By afresh adopting and blurred the book head, the Mini Deluxe forms the print, band by layer.
The downside of this action is that you can accomplish prints alone as big as the LCD screen, which, in the case of the MP Mini Deluxe, is about 4.8 x 2.7 inches. Think earlier iPhone admeasurement rather than the admeasurement of the iPhone XS. This rather baby amplitude is limiting; we couldn’t book out analysis models at their accepted size, as they aloof didn’t fit into the book area.
Credit: MonopriceThe Mini Deluxe’s book breadth is authentic by the admeasurement of the book vat, the tray that holds the aqueous resin. The abject of this vat consists of a breadth of cellophane FEP artificial that lets the UV ablaze through. This abject has to be replaced every 10 to 20 prints; new bedding of FEP artificial amount $4. The action of replacing these is rather involved, though, as you accept to aish 18 screws that authority the application arena that keeps the FEP breadth in place, afresh reinstall these screws in a assertive adjustment to accumulate the FEP breadth deeply stretched. The ailing accounting chiral that accompanies the printer fails to call this process.
Credit: MonopriceThe chiral additionally seems to be rather agilely befuddled calm and contains some amiss information. For instance, it describes how to affix the MP Mini Deluxe to a computer over a USB cable — except that this printer does not accommodate the USB anchorage that this would require. (It has alone a USB atrium for active in the USB deride drive that the printer reads book files from.)

While absolutely built, the MP Mini Deluxe has a few asperous edges. The printer comes with a ample awning that covers the book breadth aback in use, but the artificial binding on this was apart on our analysis model. The ample LCD awning on the advanced of the printer is accessible to see and use best of the time, but it’s a little adamantine to see from an angle. If the printer is sitting on a table, the awning can be adamantine to apprehend if you’re continuing over it.
The MP Mini is advised to assignment with adhesive from Monoprice, but the printer doesn’t analysis or accuse if you use added types. Monoprice does acquaint that accomplishing this can invalidate the warranty, though; so, if a third-party adhesive leaks and fills your printer with ery goo, the aggregation won’t alter your device.
Monoprice’s adhesive is appealing analytic priced; a 250ml alembic will amount you about $17, or $50 for a liter. It is accessible in eight altered colors, including back, bright and an adorable red that we acclimated in some of our tests. That amount compares able-bodied with resins for added SLA printers; Formlabs Anatomy 2’s resin, for instance, costs $149.99 a liter.
You ascendancy the MP Mini in one of two ways: through the Creation Workshop software that prepares your book for press or via the LCD blow awning on the printer anatomy that controls the press process.
Credit: MonopriceThe Creation Workshop software endless your 3D archetypal and converts it into a printable file. Monoprice offers a adaptation alone for Windows. You can use added programs, such as Cura, but they’ll crave a lot of customization to assignment with this 3D printer.
Creation Workshop is mostly accessible to use, acceptance you to amount models in assorted ways, afresh spin, scale, move and alike them as required. You afresh actualize the supports, either automatically or manually, that authority the book in abode during printing. Finally, the software slices the model, creating the alone layers that will be printed.
The affairs is appropriate and buggy, which sometimes leads to bootless prints. One example: Aback you aboriginal appetite to allotment a archetypal for printing, the affairs asks you to save the arena file, which contains the archetypal and press info. Fair enough. But afterwards you save the arena book to your adamantine drive and allotment it, you’ll save the arena book afresh to your USB drive so that it’s accessible to print. Except aback you try and book this file, it won’t work, because the additional adored book doesn’t accommodate all of the advice it needs to print; the slicing advice is not adored the additional time. Instead, you accept to save the book anon to your USB drive and afresh allotment it, autograph out the appropriate abstracts to the file. Or, you can manually archetype the actual book to the USB drive that plugs into the aback of the printer.

That’s aloof one of the abundant problems with Creation Workshop, which aloof feels ailing advised and constructed. We additionally encountered accidental crashes; annoying absurdity messages; and acutely accidental times aback the affairs aloof bedeviled up for several seconds, afresh started alive afresh after explanation.
Once you accept the book book accessible on a USB drive, you may be absorbed to admit the drive into the printer and alpha the printer running. Before you can do that, though, you accept to ample the book vat with aqueous adhesive and lower the book arch into the home position.
This printer does not acquaint you about either of these steps; balloon them, and the printer will try and book anyway, but the press won’t work. Because the MP Mini’s awning absolutely obscures the press area, you won’t see a botheration until the end or until you lift the awning and booty a blink during printing. Even then, because the book belvedere is blocked by the walls of the book vat, you apparently won’t be able to see if there is a botheration until the book is about complete.
The printer is quiet while running. The loudest babble is the quiet whirring from the fan that cools the UV LEDs on the aback of the case. The adhesive is additionally a bit stinky, with a hardly absinthian actinic odor. This actual sticks to the hands, too, so you should use gloves aback administration the adhesive or the accomplished print.

We did accept added failures with the MP Mini than we accede normal. Many prints bootless to stick to the book bed, with the afraid abeyance center through the press action or the prints advancing out malformed, with $.25 missing. Although these errors became beneath accepted as I became added accustomed with the printer, there were still a cogent cardinal of failures.
We usually analysis the acceleration of a 3D printer by creating a 4-inch-high book of “The Thinker” model. However, we were not able to book this on the MP Mini, as this archetypal would not fit into the baby book amplitude available. For that reason, we can’t analyze the MP Mini’s acceleration anon with that of added printers, but we can say that this is not a decidedly fast printer. The bigger book of “The Thinker” archetypal we were able to aftermath (about 3 inches high) took a little added than 8 hours to produce. For context, the 4-inch adaptation of that amount takes anywhere from about 7 hours to 11 hours on the Anatomy 2.
Once the book is finished, you aish it from the MP Mini’s book bed and bathe it in isopropyl booze (IPA) to aish any boundless book resin. Again, this is a rather corrupt job that requires gloves. The rinsed book should additionally be anchored with UV ablaze to accomplish abiding the adhesive is solid throughout; a few hours in sunlight or beneath UV LEDs does the trick.
For the prints that did appear out correctly, we begin that the affection of the final book produced by the MP Mini was good, with accomplished capacity and clean, aciculate edges. Our geometric-sculpture analysis archetypal came out well, with aciculate credibility and clean, bland edges.
We did acquisition that the adhesive was too bendable for our analysis book of a set of all-embracing apparatus to assignment properly, though. With this hardly bendable resin, the apparatus didn’t cobweb calm well. So, this aggregate of adhesive and printer is not absolutely acceptable for engineering or added types of press that charge genitalia that move adjoin anniversary other. Monoprice does not action a added adamant blazon of resin, but added manufacturers do.
The MP Mini Deluxe is the lowest-cost adhesive printer we’ve yet tested, but it feels like a absent opportunity. It’s a actual careful printer that requires a lot of tweaking and agreement to use, and press is actual hit and miss. Inexperienced users would apparently try a brace of prints, afresh accord up in abhorrence because of the poor software, poor manual, bootless prints and accepted complications of the printer.
Monoprice’s printer ability address to a 3D press enthusiast who has bound funds and doesn’t apperception putting in the assignment to amount out how to get the best affection out of it. Best users who appetite hassle-free press will be bigger off spending added on an SLA printer that is better-designed and complete like the Peopoly Moai. Or they should aloof stick with a cheaper FDM printer that’s added reliable, like the XYZprinting Da Vinci Mini.
