The argument that 3D printing processes are too slow is a false one. My wife’s Subaru is slower than my BMW M3. Does that mean I should only drive the M3? It had better not. I use the Subaru to haul stuff with a trailer while taking the M3 to the racetrack for performance driving schools. Different uses, different vehicles.
The same holds true with 3D printing. Astute users know there is no ideal, one-size-fits-all 3D printer. Instead, they employ the right tool for the job.
Massivit’s large-format 3D printers with gel dispensing technology (GDP) are a case in point. GDP uses an acrylic-based material, so metal parts are out. But unlike material extrusion printers using ABS and other plastics, Massivit’s UV-cured gel materials enable higher speeds and larger sizes. Like up to 101.6 cubic feet.
I attended the grand opening of Massivit’s new Experience Center in Alpharetta, Georgia, last week. A large lobby welcomes visitors with displays showcasing the large prototypes, models, signage, and other examples of GDP output. Visitors walk past meeting spaces into the demonstration area, outfitted with a model 5000, a model 1800 printer and ample space for more.
The event opened with comments from NA President Kevin Sykes, followed by staff presentations. Mr. Sykes talked about how “speed unlocks size.” Capable of printing 14″ per hour in the Z-axis, the model 5000 can print a 3′ diameter cylinder that is 6′ tall in six hours. Of course, few businesses will 3D print such a large cylinder, but the shape provides a reasonable benchmark. The most accurate way to determine actual speed is to 3D print your parts.
Massivit’s markets include aerospace, automotive, furniture, marine, railroad, scenic fabrication, and sign & display industries. Basically, any market that benefits from large prototypes, tooling, molds, or finished products.

Massivit’s speed, coupled with immediate UV curing of the GDP gel, means layers are bound to each other as the build occurs. The speed means long dispensing paths are not a problem, nor are overhangs. In many cases, GDP printing does not require support structures. However, given the acrylic’s 1% shrinkage (a factor other 3D printers also face), support structures may be printed when precise dimensions are required. Depending on your requirements, Massivit’s 3D printers offer 1.5 mm, 1.3 mm, 1.0 mm, 0.8 mm, and 0.5 mm layer thickness options that you can use to balance speed with smoothness and fine details.
Minimal support structure use means little of the gel must be trimmed and tossed out, saving material and labor costs. The result is a significantly better “buy to fly” ratio compared to other 3D printing and conventional manufacturing technologies, whether you print aerospace parts or not.
Massivit printer list prices range from $269,000 to $375,000 for the 1800 printer in various configurations to $450,000 for the 5000 printer. The materials range in price from $40/kilo to $100/kilo, depending on the gel and amount purchased. In addition to your sources, the company offers various equipment and material purchase and leasing options.
I highly recommend visiting Massivit’s Customer Experience Center to see the equipment for yourself, discuss the wide range of large-scale parts and composite mold production applications, and have a sample of your parts produced.
I have evaluated, justified, implemented, and consulted on numerous capital equipment purchases over the years, including ones that cost several hundred thousand dollars. Regardless of size, every one of them put my career – and my employer’s business – on the line.
There is no greater satisfaction for people like you and me, who work on big, important purchases than to have the equipment up and running successfully from Day One. How I can help you?
