3D printed House

Hi everybody, How are you guys? is growing with you and we need to know about your valuable experience with sv3dprinter. is 5 years old and most of our friend followers are with us for several years. ´Yay´! for our friendship.
opportunity to thank you for reading our articles amidst all the challenges and adversity that was. This will certainly amazing to remember!
Few things I want to ask you if you get a chance please feel free to share with us.
Please tell us your story about how long you are with
What did you like and what you didn’t like and why?
What should we improve?
If you had any purchase regarding 3d printing what was it?
If you are still using it, what improvement would you want to see in that product?
I love hearing from my friends!
We are trying to continue to share articles the same as before.
All the best to all of you,
Thank you so much.


Elegoo Saturn MSLA 3D Printer

From comments,

When a 3d printer uses an LCD to polymerize the photopolymer it is known as DLP (Digital Light Processing). When a 3d printer uses a laser to polymerize the photopolymer it is known as SLA (Stereolithography). Great video keep up the good work!
Nice review! With regard to your “fingerprint” issue, it’s a little bit hard to say what it could be without seeing how it was positioned when you printed it and such, but it could be caused by a number of different things, from curing time per layer, to anomalies with the actual layers being displayed on the screen. Does the printer have automatic anti-aliasing? I’ve been wondering for some time if that might cause some issues like that, due to the somewhat semi-transparent nature of anti-aliased pixels, I suspect they could cause surface oddities like that to appear. In theory they should help a little to keep the surface smooth, but if the image you’re using is being displayed on a high enough resolution screen, it shouldn’t really be needed either. Definitely something worth experimenting with though 🙂
Awesome video! I definitely plan on getting an SLA printer soon. I’m still sorta new to 3D printing, would it be worth it to get this printer as an SLA beginner or go with something else?
You should look into getting some large silicone mat trays. Ones with a rim around the sides to keep spills within the mat. You should buy one for under the printer itself, and then a second one for the cleaning area where you clean the prints and vat. When you search for them, say in Amazon, search for a “dog cat silicone mat tray”. They have some dcent sized ones for a decent price. I purchased a pair for my resin printers and they work great. They will definitely keep any mess from getting all over the place and are easy to clean as well.
@Jack Evans The Elegoo Saturn has a lot of benefits to its use. Because of the 4k mono color screen that it uses, it can print at a higher level of definition than FDM, at roughly four times the speed of other resin printers, including the elegoo mars. And because of its larger build area, its easier to print larger figures that would have been required to be split up into smaller pieces on a tinier machine.

Relativity Space to build the first rocket 3D Printing factory

Posted on Updated on

With backing from NASA, rocket startup Relativity Space is creating the first autonomous rocket factory. The company is planning to produce 95% of rocket components with 3D printing, and the first orbital launch is expected in late 2020.

The new agreement will provide the California-based startup with exclusive access to NASA’s infrastructure and financial aid from the Mississippi Development Authority for building a large-scale highly automated 3D printing rocket factory. The company will lease a 20,000-square-meter building at NASA’s John C. Stennis Space Center for nine years. The test stands and all the necessary equipment on the site allow for convenient engine testing. The agreement provides an option to extend the lease for another 10 years. The company aims to create 200 jobs and invest $59 million in the state. In exchange, the state of Mississippi offers a reimbursement of expenses and a tax incentive package.



The new factory will produce Relativity Space’s first 3D printed rocket – Terran 1. This vehicle can carry up to 2,756 lbs. into low Earth orbit. Both stages will be powered by 3D printed Aeon engines fueled by methane and liquid oxygen. The first stage will be powered by nine engines, stage two will be equipped with only one. The rocket is priced at $10 million per launch. It is expected that due to the use of the 3D printing technology the manufacturing cycle will not exceed 60 days. 

Although the company is planning to construct its own launch facility, the first rockets will be launched from Cape Canaveral. The launchpad and all the supporting infrastructure will be provided by the U.S. Air Force. The company was allowed to use Launch Complex (LC) 16, which was built for tests of Titan I and Titan II, and then Pershing I and Pershing II missiles. The last launch took place there in 1988. 





Most of the metal parts will be manufactured by Stargate, Relativity Space’s first 3D printer. The scalable system features multi-axis robotic arms with lasers. The machine uses metal wire feedstock as a printing material. In February 2019, Relativity Space was granted a machine learning 3D metal printing patent, issued for “real-time adaptive control of additive manufacturing processes using machine learning” (US20180341248A1).

“This agreement demonstrates again NASA’s commitment to work with our industry partners to expand commercial access to low Earth orbit. This helps NASA maintain focus on the ambitious Artemis program that will land the first female and the next male on the south pole of the Moon by 2024,” said Rick Gilbrech, director of  Stennis Space Center. “Relativity is a valuable member of the Stennis federal city and we look forward to building on our already successful partnership.”

The first orbital launch is expected in 2020. The company is planning to enter the commercial market in 2021.
