sparkmaker lcd screen in stock

SparkMaker is a resin printer, which was successfully funded through Kickstarter. It uses an LCD screen to cure the resin. The printer is ready-to-use from the box. It had been mentioned numerous times as one of the most affordable resin printers on the market as well as an easy to use the machine. Sparkmaker comes with its own slicing software and allows to use of third-party resins.

About a year later they even came out with an upgraded version, the Sparkmaker FHD, that increased the print resolution from 480p to 1080p, a major and needed jump in fidelity.

The Sparkmaker Original, in addition to having a really low resolution display, only understands black and white input images. So, natively, there is no way to feed it anti-aliased source images to smooth out the large pixels.

Sparkmaker FHD is the new and improved version of this printer and in addition to a higher resolution screen it is also equipped with a more powerful UV backlight.

Unfortunately, this backlight produces a very uneven exposure across the screen with hotspots directly under the LEDs as well as areas where the light cones overlap.

So in theory, if we can measure the intensity of the UV light that hits the screen at each pixel, we could use the LCD screen to compensate this overexposure and normalize the light.

[SLA 3D Resin Printer for Precise Printing] – Solid built and industry-grade Z-axis linear guide is easy to level, allowed to print at 100 micrometer XY resolution and up to 20 micrometer Z layer thickness, ensuring a higher resolution and stability but avoiding wavy lines during printing. Unlike most FDM SLA LCD 3D printer, 24 UV LED light sources inside are uniformly distributed in each parallel panel, which delivers more evenly radiation so that print out a better-shaped and preciser model.

[One-click Operation & Fully Assembled] – This family-friendly mini desktop SLA 3D printer is almost fully assembled, best choice for hobbyist, beginners and professionals or as a Halloween Christmas gift. Printing platform, leveling device, resin tank and slicing software are already set up, you can get started right out of the box. One click of the button to start, pause or stop as you required, so that you can operate it flexibly and worry free with this easy-to-use LCD 3D printer.

[Multiple & High-end Resin Material] – SparkMaker photosensitive resin features standout rigidity, elasticity, hardness, super clear while they show great performance in kids education and family entertainment, industrial & medical parts modeling. We have adopted imported photoinitiator so it has stable color paste and helps model shape up faster and preciser with less smell producing. The durable all metal resin tank is removable and easy to clean, which also can avoid resin leakage.

Most 3D printers today use the FFF (Fused Filament Fabrication) process, which is also sometimes referred to by the proprietary FDM (Fused Deposition Modeling) name. Those printers work by melting thermoplastic filament, and then extruding the plastic onto the build plate in layers. That process is quick, affordable, and produces relatively strong parts. But the SLA (Stereolithography) printing process generally yields higher quality results. SLA 3D printers used to be expensive, butthe SparkMaker Original is very affordable, and I recently tested one out.

The SparkMaker Original launched on Kickstarter back in 2017, and it’s still one of the most inexpensive SLA3D printerson the market. The SLA printing process works using photopolymer resin that hardens when it’s exposed to UV light. That light can come from lasers or from LEDs that are masked by an LCD screen. The latter method is cheaper, and is what the SparkMaker Original utilizes. The XY resolution is determined by the resolution of that LCD screen — 720p in this case.

On paper, the SparkMaker Original has some respectable specifications: a 98*55*125mm build volume, a 0.1mm XY resolution, a 0.02mm Z layer thickness, and a single layer print time of 8–15 seconds. There are a variety of resin types available depending on your intended applications, and the printer is very compact and desktop-friendly. But to find out if it’s actually any good, I had to test it out for myself.

The first thing I noticed is how small the SparkMaker Original is — the entire machine is roughly the size of a gallon jug. It came packaged securely in styrofoam with everything I needed to get started, including a bottle of standard LCD-BW resin. Best of all, no assembly was required. The only thing that needs to be done before printing is to level the build plate, which is a process that takes less than a minute.

After the build plate is leveled, you can use the free SparkStudio software to slicean STL 3D modeland copy it over to the included SD card. The software is very simple, and comes pre-configured for the SparkMaker Original and a handful of their resin types. The only downside is that you can only have one printable file on the SD card at any given time, as ithasto be called “print.wow” to work.

Once your model is sliced and on the SD card, you can insert it back into the 3D printer. Then follow the proper safety precautions to fill the reservoir with resin — it’s toxic, so be very careful and wear gloves and safety glasses. Strangely, the power switch is on the cord coming from the power supply, and there is no switch on the machine itself. Once it’s on, you just push the dial in to start the print. There is no screen, no way to select specific files, and no way to connect the printer to you computer.

For one last test, I printed the sphere below. This one was printed on “fast” settings. This turned out well, likely because there were no fine details. This model is ideal for the smooth surfaces that the SparkMaker Original seems to want to produce.

But what if quality is less important to you than reliability? Unfortunately, that doesn’t seem to be a strong point here either. Every other print job I tried completely failed. That was because the LCD window would become covered in a layer of semi-cured resin. In order to get a successful print, I had to completely empty the reservoir and then carefully peel off that layer of resin. That’s a tricky job considering the toxicity of the resin.

Finally, I have some nitpicks about the mechanical design of the machine. The most glaring is that the top of the build plate is completely flat, so resin will pool there. Virtually every other SLA printer has the top of the build plate sloped to avoid that, but it seems SparkMaker was cutting costs here. The protective UV-resistant cover also doesn’t have anything to hold it in place, so a bump can push it into the build plate.

At the end of the day, I can’t recommend the SparkMaker Original with a good conscience. It’s very affordable at just $249 (even less with a coupon), but there are other models on the market at comparable price points with better specifications, additional features, and more favorable reviews.
