In a departure from the widely used FDM technology found in the majority of consumer 3D printers, Formlabs jumps off the bandwagon to offer a small form factor desktop SLA printer at a fraction of the usual cost.
On the back of a tremendously successful Kickstarter crowdfunding campaign that raised an eye-watering $3 million in the space of few months, the Form 1 and its advanced version, the Form 1 +, strives to bring the precision-oriented SLA technique to the masses.
How does it rival the standard FDM design and has Formlabs succeed in its mission to bring professional-grade quality free of the variable quality of other low-cost 3D printers to the average maker? Let’s find out.

Design and Features
Most striking is the orange acrylic cover that sits above a glossy grey base with soft contours, an efficient closed look, and a definite nod towards Formlab investing considerable time and money into generating a visually enticing device. The Form 1 + is well constructed with an intelligent design from the placement of the different components, the latched removable inverted build plate, and functional resin reservoir.
It’s easy to forget that the Form 1 + is supposed to sit alongside entry-level pre-assembled 3D printers due to how good it looks. It oozes precision and professionalism with an almost otherworldly attraction that drew us inexplicably to this machine. The total weight of 18 lbs is worth noting as it ensures the printer stands firmly on any surface with a robust set of low-profile feet.
As mentioned above it uses SLA tech, or inverted stereolithography, which involves a UV laser that cures or hardens a light-sensitive liquid plastic resin layer by layer into a solid object. The galvanometer-directed UV laser effectively draws on the surface of the liquid resin causing it to harden. Delving a little deeper the process centers on a process called photopolymerization, whereby molecules are fused and solidified when in contact with light to create polymers.
As you can see, this is miles away from the, at times, slapdash FDM technique, where plastic is melted then extruded layer by layer to create a printed model. Consequently, SLA usually carries with it a non-negligible price tag, if only for the equipment itself, but also for the actual liquid resin.
But the jump in price is also synonymous with a massive leap in quality as well. The results are incomparable to standard FDM tech, and if you were to put two identical models made via each of the technologies alongside one another, you’d be amazed by how much better the SLA printer performed.
The benefits don’t stop there, SLA is all but silent and long are the days of abrasive mechanical ear sores emanating from an FDM printer three rooms away. Equally, it is arguably safer due to only reaching temperatures ranging from 18 to 28 degrees centigrade compared to the standard 100 + degrees recorded during the operation of conventional 3D printers.
Now, to jump back to the hinged orange casing mentioned previously, it serves a fundamental purposes as it blocks outside light from infiltrating the closed chamber and spoiling the resin as well as looking pretty cool.
The Form 1 + packs a decent build area of 125 mm x 125 mm x 165 mm that is somewhat constrained by the incremental cost of SLA printing. The build volume took a hit to make the printer cost-effective. It’s smaller than most similarly priced FDM equivalents, but the upside is much better precision and detail.
At this point in our review, we would usually dive into extruder specifics, but as the Form 1 + doesn’t have one we jump to layer resolutions that range from an ultra-precise 25 to 100 microns alongside a minimum feature size of 300 microns (i.e., features of a model).
As for the resin itself, it is made of acrylate-based materials with an NPCA HMIS health safety rating of 2 (read moderately hazardous) and is produced exclusively by Formlabs and is, as expected, pretty expensive at around $150 for 500 mL, but much cheaper than the resin used for professional-grade machines. The standard resin is engineered for high-resolution details as well as strength and durability.
Formlabs offers a range of colors and finishes alongside castable and flexible resins. Third-party resins aren’t supported and unfortunately won’t work with the Form 1 +.
Formlabs believes in simplicity and no more so than in the controls on the Form 1 +, which is nothing more than a one-button control panel with monochromatic LCD.
Otherwise, connectivity is limited to USB-to-PC via Formlabs slicing/preparation software dubbed PreForm with inbuilt tools for orientation, rotation, scaling, duplication, support generation and placement, density and geometry options, monitoring and print time estimates, and STL/OBJ file support (pulled from any 3D CAD software) converted to FORM for the Form 1+ to read. PreForm is compatible with both Windows and MacOS.
PreForm is easy to use, intuitive, and definitely among the best proprietary forced usage software we’ve come across in our years of 3D printing.
Assembly
The Form 1 + comes amply protected in a package of suspended cardboard inserts holding the printer in place, edge protectors, and protective tape.
Unpacking involves removing the printer while being careful not to damage the packaging as it is designed for reuse when transporting the Form 1 +.
The package includes the Form 1 +, USB cable, power cord, power adapter, official documentation, quick start guide, safety guide, a 1L bottle of resin, and a Form Finishing Kit (setup guide, rinse bucket, rinse basket, tray, scraper, squeeze bottle, tweezers, absorbent pad, and disposable nitrile gloves).
The Form 1 + comes pre-assembled, and we mean genuinely, pre-assembled. No messing around fitting extruders, build plates, or filament spools. Due to the SLA tech, there’s no bed leveling or calibration either. It is functional straight out of the box.
Setup couldn’t be easier: remove the plastic protective layer from the resin tank paying attention not to smudge the bottom or top, plug in the power cord to the adapter and socket, connect the USB cable to the printer then PC, and finally switch on the Form 1 + via the button next to the display screen.
Print preparation is limited to filling the resin tank with liquid resin up to the marked line. Gloves are recommended which is a slight inconvenience, but otherwise, the process couldn’t be more straightforward.
Printing
For someone accustomed to FDM printers, the Form 1 + was a revelation. The quality of the prints can only be described as outstanding to the point that we’re genuinely dreading going back to FDM models.
The quality of the precision allows finite details on models to be abundantly apparent and not merely a blotched mesh of vaguely resembling filament that is so often the case with FDM. Every model we printed came out great with more detail than we are accustomed to in consumer/prosumer 3D prints.
The whole setup, slicing, and print initiation setup was also a pleasure and a world away from the overly complicated procedure usually associated with SLA style 3D printing. We did not once face any issues or failed prints at all.
The printer is also reasonably fast, and the revised Form 1 + is up to 50 times faster due to an improved UV laser and optics.
The finishing kit is also excellently designed with brackets to fit the detached build plate while you scrape off the model and an efficient rinse basket. The supports were easy enough to remove with a little force; a sure sign they were doing their job during the printing process.
The one real issue we had with the Form 1 +, but that comes with the SLA territory, was how meticulous we had to be in keeping the device clean. Any stray finger marks or blemishes on the resin tank meant cleaning it from top to bottom or risk ruining the curing process due to the precision of the optics, mirrors, and UV laser.
Support
Although Formlabs has technically stopped producing the Form 1 + in favor of the Form 2, they stay committed to providing expert after-sales support as well as a free one-year warranty, manning a repairs and servicing team, and providing educational resources from articles to videos by way of webinars and troubleshooting guides on its website.
Verdict
The Form 1 + takes the precision and quality of professional SLA printers, miniaturizes it, simplifies the printing process, and produces high-resolution prints with a nearly perfect finish.
If you want something different to the standard FDM design, then the Form 1 + offers the ideal all-in-one package to get your feet wet.
Although the ongoing cost of resupplying the resin tank can prove costly overtime, the Form 1 + uses resin sparingly, and we were surprised by how many models we were able to pump out with the stock 1L bottle. The long term cost is worth keeping in mind, but not a deal breaker in our book.
The cost of the resin means you won’t use it to create and experiment with test models. We see it more as finishing tool for low tolerance prototyping and models for casting.
The price tag hovers around the $3000 mark so this printer isn’t necessarily within the realm of the novice or first-time buyer, but veterans on the lookout for a new addition to their collection will find a lot of joy in the Form 1 +.
Review: Formlabs Form 1 | WIRED
The current king of at-home 3D printers is the MakerBot Replicator 2. The latest-generation machine from the MakerBot folks has so far proven to be wildly popular with the DIY and hobbyist crowd, as well as artists and students.
And its popularity makes sense: the machine is fast, easy to use, runs on good software, and is supported by an online community of people eager to share their designs. It costs $2,550, about as much as a beater automobile.
There's something undeniably cool about printing with lasers.But the Replicator 2 is limited by its printing mechanism, which (like many other 3D printers) uses heated polyester filament to build models in three dimensions. The machine basically acts like a super-accurate hot glue gun, adding the material layer by layer. It has a maximum resolution of 0.1 millimeters per layer (about 1/250th of an inch) which is good enough for most home applications like model-making and small parts replacement, but not accurate enough for people working with crazy-intricate designs.
The Form 1 is built for more demanding work. It prints objects by way of stereolithography, a form of 3D fabrication that uses an ultraviolet laser to cure liquid plastic resin. A laser "draws" the object by shooting into a reservoir filled with resin, and the resin hardens layer by layer as the laser does its work.
This method gives you a very high-resolution print – 0.025 millimeters per layer, or 1/1000th of an inch – so it's better suited to late-stage prototyping, tiny parts replacement, jewelry, and other things that require perfect edges and incredibly fine details. Stereolithography machines are professional tools. So of course, they're inaccessible to most people, enormous machines that cost hundreds of thousand of dollars.
But the Form 1 is very small and relatively cheap – $3,300 for the unit and $150 per liter of resin. Also, the company's custom PreForm software that runs the printer is very easy to use and is available as a free download for Windows and Mac OS X. It's a pro machine built for the mass market.
The company set up a Kickstarter last year to produce the machines, and raised almost $3 million. The first Form 1 printers have been rolling out to early adopters for the last few months, but if you want one, you can pre-order and get it around the end of 2013. Formlabs sent us a first-run unit to test, along with a liter of clear resin and the "finish kit," which is a small assembly of tools for dressing your completed print.
The Form 1 itself is only 18 inches tall and has a footprint of about one square foot. Also, it's beautiful. The hinged lid is crafted from a translucent orange plastic which, in addition to lending the Form 1 a striking, colorful visage and allowing you to safely watch the printer in action, also serves to protect the resin tray inside from UV light. You can leave the reservoir filled with resin and, as long as the lid stays closed, the liquid will remain uncured until you hit it with the laser.
Setting the rig up for printing is as simple as plugging the Form 1 into the wall, connecting it to your PC via a USB cable, and installing the software. After that, you have to find something to print. The machine is limited to printing objects less than 4.9 inches wide, 4.9 inches deep, and 6.5 inches tall (though like with other 3D printers, you can make larger objects if you print pieces separately and join them together).
You can drop any .STL file from almost any CAD program into the software, or you can do what I did and turn to one of the internet's various repositories for 3D printing enthusiasts.
For my first test print, I searched for objects specifically made for printing on the Form 1, or at least things posted by other Form 1 owners so I could compare my results against theirs. There weren't many out there – objects made for testing the Form 1 or actual Form 1 owners – given how new the machine is. But I did find this cute little robot pendant by Gregg Wygonik. He described it as "simple, tiny, and intricate," and he modeled it in Blender specifically for testing his Form 1. Exactly what I was looking for. I downloaded the robot and gave it a go.
The printer offers a few default resolutions: the high resolution of 0.025mm per layer, a medium resolution of 0.05mm per layer, and a low resolution of 0.1mm per layer. For the first print, I decided to try out the highest resolution first. I loaded the robot's file into the PreForm software, selected the default support option, which tilted the figurine's body about 20 degrees from prone and inserted a bunch of support pegs into his back.
Clicking the big "print" button loads the instructions to the printer – you can see this happening by watching the only display on the printer itself, a small LCD screen on the front of the case. After a couple of minutes, the printer's LCD reads "Ready to Print," and you set things in motion by pressing the big button next to the display.

Formlabs Form 1+ 3D Printer (SLA)
Form 1 + Printer from Formlabs, which uses laser stereolithography instead of extrusion - the layering of molten plastic - the object is formed by the thinnest layers of resin, photopolymerized under the action of a laser, which ensures the highest printing accuracy at 25 microns. Projects are very smooth with little need for post-processing, and thanks to the high print quality, you can create a model that matches the digital sample down to the smallest detail.

Technical features:
Another feature of the Form 1+ is the ability to print parts with so-called "hanging parts" that extruder (FDM) printers rarely can offer. (Print without support)
Changes in Formlabs Form 1+ compared to the first version of the 3D printer:
- Print speed increased by 2 times
- 2nd generation laser, laser power increased by 4 times
- Print quality improved nine0119
Installation:
The Form 1+ is the simplest printer in the world in terms of setup and connection. You connect it via USB to a computer, select the desired file in the program and then send it for printing. The file is being downloaded to the printer, at this time the cable must not be pulled out, otherwise printing will not start. In 5-10 minutes, the file goes to the printer, and then you can turn off your computer, remove the wire, this will not affect printing in any way.
Features of use:
The printer indicator shows the progress of printing, which layer is in operation and the remaining time.
