Due to manufacturing issues, in recent months there has been a very limited supply of ABS MG94 pellets.  We ran out in December and have been working hard to try and get some at a price where we will not have to double what we have charged in the past.  We finally made a deal to get some in and had it arrive last week (13 April 2017).

While we were working these deals, we found an ABS product that performs REALLY close to MG94 and in our opinion somewhat better in printing bridges, but we’ll leave that for you to decide.  This new plastic is made by Kumho and is their 750SW Natural product.

To celebrate the return of MG94 to our store we are offering a 5% discount (5FORMG94) till the end of May on our ABS products and also a discount code to keep the free shipping (FREESHIPPOWDERWITHBUNDLE) while adding one of our Powder Colorant Bundles to the Free Shipping Pellet Bundles.



Business sold and Store now re-opened

My name is Jonathan Shaw.  I purchased the business assets from Rob.  I hope to continue in his shoes and provide materials that the community needs.  If you have any questions or suggestions on new products/colors, let me know and we can look into providing those that are most popular.  In future weeks we hope to fully convert to our new domain.  We will still keep the old domain ported to the new site so that both ways will access the store.  The new domain http://www.os3dp.com currently points to our old store store.osprintingllc.com.

Thank You for your continued support.

Filastruder Enclosure V2


We have finished revamping our filastruder enclosure. Here is what we have changed:

One of the biggest changes is the guide assembly. It is now a single printed part that mounts to the front support. It uses a 50mm fan instead of a 80mm fan. It also uses a single guide. At 4ft and using ABS, we got great results and holding tolerences of +-.05mm.

We added a spine to the enclosure. That makes the overall enclosure more rigid. This will help with the newer motors additional torque and allows for operation without the back panel.

The supports went from 1/2 ply to 3/4 ply. This prevents de-lamination of the plywood from the threaded inserts.

We have added two T-nuts to the spine. This allows for the machine to be wall mounted using two 1/4-20 bolts.


You can find the new enclosure at store.osprintingllc.com or http://www.thingiverse.com/thing:274933.

FilaWinder only $179.99
We have started selling the FilaWinder. A fully automated filament winder that utilized a feedback loop to maintain high filament tolerances. This is great for people who want their filament operation to take up less space or don’t want filament coiling on the ground.

Vapor Print Finisher
The Vapor Print Finisher(VPF) is a hotplate that can be used to perform acetone vapor baths. An acetone vapor bath uses acetone vapors to smooth out a 3D printed ABS part. Giving your prints a smooth glossy finish. The VPF is small and compact and gives you the freedom to perform vapor baths in well ventilated areas.
