The SparkMaker began life as a $99 Kickstarter, which I was understandably skeptical of. Not only was that a ludicrously cheap price for a 3D printer, it was absolutely preposterous for an SLA 3D printer – which was previously the domain of much more expensive industrial printers. It"s now in production, shipping to backers, and available for just shy of $300 from OGadget for everyone else – but is it worth it?

An SLA (or StereoLithography Apparatus) printer uses photosensitive resin as the raw material (a liquid), which solidifies when exposed to UV light. This can come either from a moving UV laser, or in the case of the SparkMaker, UV LEDs and an LCD screen to mask off each layer. As the print solidifies, it"s pulled out of the resin tank.

The SparkMaker has a total build area of around 4 x 2.2 x 5 inches (102 x 56 x 125 mm). The unit itself measures just under 11 inches (275 mm) tall with a diameter of 6.5 inches (165 mm). It"s compact, and looks quite neat on your desktop. Everything is enclosed in the large translucent red cover, though this isn"t fixed in any way, it just sits on the base.

Also in terms of safety (yep, there"s more) – don"t power on at the plug socket until you"ve inserted the DC power jack into the unit, or you"ll get literally sparks. That"s right, the SparkMaker makes sparks when it"s plugged in. You couldn"t make this up if you tried.

Using the SparkMaker is (frustratingly) simple. The only method of getting a print onto the device is through the included SD card. It can only hold a single print at a time, so you"ll need to head back to a PC to transfer another file over. There is no USB connection or Ethernet port, and it can"t be interfaced with Octoprint. When you"re ready to print, fill the resin vat with your choice of resin, to approximately 1/4 inch (6mm) deep, put the cover on, and press the single button. The print bed will be lowered into the vat, and begin printing. Cleanup and post-processing is lot more effort, though.

If you want to slice your own models, you"ll need to download the Windows-only (at the time of writing, though a Mac OS version is promised) custom software, called SparkStudio. This includes settings specific to the printer and type of resins, and will output a "print.wow" file. The files are around 50-100MB in my experience, which is larger than your typical G-code file. G-Code files for FDM printers are really just text commands that describe movements of the print head. I suspect the SLA files are larger because they contain thousands of "images" for what must be displayed on the LCD screen and cured on each layer, effectively a little video file.

SparkMaker offers a range of resins at around $50-80 for 500g. The cost per gram is significantly higher than plastic filaments (at least five times as much), though the objects you print will be smaller. As mentioned, you"ll need 99% Isopropyl Alcohol to clean the prints and resin vat after each print. However, SparkMaker have produced an alternative resin (LCD-W), which can be cleaned up with just water. This is a great option that avoids noxious smells and makes the whole experience a bit safer and cleaner. The prints made of LCD-W tend to be quite brittle, however, so it isn"t quite the ideal solution. The resins are clear, but can be tinted with special color mixes.

Sadly, after extensive testing with both LCD-W and LCD-E ("Elastic") resin, using either the pre-sliced models that SparkMaker offer or custom sliced using their software, we were unable to get a fully successful print out of the device. This is as far as we got with a Hero Forge sample mini – you can see the supports failed much earlier, so the rest of the model didn"t really have a chance:

Unfortunately, I just can"t recommend the SparkMaker – not at the moment anyway. The closed Facebook group is full of posts from people experiencing similar frustrations. Those that have had success appear to be both replacing the FEP film out of the box, and doing a modification to bring the LCD screen closer to the bed. The latest announcement indicates that SparkMaker have made some hardware improvements for pre-orders that haven"t yet shipping, so that"s a good sign the issues have been identified. If you order now, you may not face the same problems. However, we can obviously only report on our experience.

In a break to the norm, we won"t be running a giveaway for the SparkMaker: you"d spend more on consumables and accessories than you"d get out of it. I"ll be following the modding process, replacing the FEP sheet, keeping an eye on software updates, and trying again. If results improve, I"ll update this review accordingly.
