Up mini 3D Printer

The newest way to print quality 3D models right from your desk for visualisation, collaboration, and functional prototyping testing.

The UP! Mini is based on the simplicity of a traditional inkjet printer, with a snap in printer head, slide in build table and clip in consumable roll. You are now ready to start printing your big ideas into Three Dimensional usable models out of tough ABS plastic.

There is no sacrifice on build quality with the UP! Mini, with its enclosed steel construction, double linear bearings on each axis and a temperature stabilizing build chamber; it is ready to produce quality parts on your desk within 15 minutes from switching it on.

"The UP! Mini is the result of thousands of hours of field testing & valuable feedback from our rapidly growing UP! user community."

The new UP Mini Desktop 3D Printer is simple and affordable. Using additive manufacturing technology to lay down successive layers of ABS to build up a printed three dimensional model. 3D Print whatever you want, whenever you want and as any times as you want.

Specifications

·         Build footprint of 120 x 120 x 120mm with heated build table.

·         Heat retention chamber to reduce warping.

·         Double linear bearings on each axis - ensures consistent build quality throughout the entire print process.

·         Print speed of 9mins per cm^3.

·         Layer resolution of 200 microns.

·         Chip free and open consumables – You can use any suppliers ABS roll of 1.75mm plastic with your UP! Mini. The UP! Mini consumable is an open design so you are not locked into expensive consumables as opposed to expensive inkjet cartridges.

·         USB interface for inkjet simplicity print spooling, you can unplug your computer once the UP! Mini starts printing.

·         Includes the Smart UP! Software, tools and a full roll of plastic to get you started.

3D Printer Tricks – Quick Threaded Holes

While working in the machine shop the other day, curiosity got the best of me. I was thinking abouthow to add fasteners to my printed part, but with a minimal amount of work. Fasteners can be drilled and tapped, Helicoil-ed, or ultrasonically welded into ABS parts. If the thread is large enough, it can even be modeled on the part directly, but what about smaller fasteners?
Typically, to create a threaded hole on a 3D Printed part, we would need to perform a few operations on another machine.  First, the part and the hole position would need to be located precisely, straight and true (“tramming and indicating”). Second, three tools need to be used: a center drill for the pilot hole, a tap drill of a specific size, and finally a tap. All these tools need to be used in the exact same location in order to generate an accurate screw thread profile. This is standard operating procedure with a CNC machine. However, you’re probably using a 3d printer to avoid the machine shop in the first place. You can save a few steps by inserting the tap drill size directly into the 3d print, with impressive results.

By printing parts with the tap holes already modeled in, we can eliminate several extra steps in the process, and the need of using a separate machine. Hand-tapping the precisely located holes is adequate for creating a functional thread.

The smallest thread in the test is marked, “4-40”, the tap hole is printed at .089”, and hand-tapped afterward.

The thread felt a little loose, indicating an oversize minor diameter. To remedy that, the tap hole can be made slightly undersize.  With a smaller tap hole, the slop wasn’t so dramatic of a concern on the larger threads (the largest here being 1/2-13).  Loose fit wasn’t a problem at all with the two tapered threads in the upper left hand side, a 1/8-27 NPT and 1/4-18 NPT.

By printing the tap holes directly into the part, we avoid several steps typically needed to insert threads into 3d printed parts, only needing threading.  All of these threads were created with a hand tap, and as long as the tap goes in relatively straight, it produces quality threads without all the usual effort.
