Week 6 group assignment 3D printing

Introduction to the 3D printers

LeapFrog Creatr HS

https://creatrhs.lpfrg.com/support/home

FDM prinsible printer with heated bed. The price range is about 1,800€. It is one of the oldest machines we have in the Fablab. It is Leapfrog but only by name because we replaced the brain of the printer with completely different things. However, it has really nice frame. We use a raspberry pi connnected to arduino mega. The arduino mega trigers the boards. The raspberry pi has clipper installed which is a 3D printing software that can run on a small computer like raspberry pi.

Testing for design rules

Test 1

Picture4:Test1 - LeapFrog Creatr HS

Picture5:Test1 - Raise 3D pro2

Picture6:Test1 - Formlabs form3

Angle and overhang:

LeapFrog Creatr HS: flawless overhang until 40 degrees after that quality starts declining

Raise 3D pro2: flawless overhang until 60 degrees after that quality starts declining

Formlabs Form3: best result, no drooping.

Bridging:

LeapFrog Creatr HS: 15 mm has macaroni droop

Raise 3D pro2: Fine even with 25 mm length

Formlabs Form2: Bad “melted” uneven bridges, and a split on 25 mm bridge

Hole:

LeapFrog Creatr HS: 0,1 mm smaller

Raise 3D pro2: Almost exact

Formlabs Form3: 0,1 mm smaller

Scale:

Measurement in design 10 mm

LeapFrog Creatr HS: Almost exact 2,15 mm vertical, 2,12 mm horizontal, Squere 2,00 x 1,99

Raise 3D pro2: 1,69 mm vertical, 2,02 mm horizontal, Square 1,69 x 1,64

Formlabs Form3: 2,01 mm vertical, 2,01 mm horizontal, Square 2,01 x 2,00

Stringing:

LeapFrog Creatr HS: Lots of stringing

Raise 3D pro2: few

Formlabs Form3: not possible

Diameter:

Measurements in design 6 mm and 8 mm

LeapFrog Creatr HS: 5,72 mm, 8,00 mm

Raise 3D pro2: 6,14 mm and 7,93 mm

Formlabs Form3: 5,88 mm and 7,97 mm

Test 2

Wall Thickness:

LeapFrog Creatr HS: all walls were made. All holes were made except for .1 and .2.

Picture7:Test2 - LeapFrog Creatr HS

Raise 3D pro2: .1 wall didn't print. All holes were made except for .1 and .2.

Picture8:Test2 - Raise 3D pro2

Formlabs Form3: All walls printed ok, and the holes.This gives the best quality.

Overhang:

The test pieces were printed with support.

LeapFrog Creatr HS: With supports overhang printed just fine.

Raise 3D pro2: the piece was broken while erasing the support.

Formlabs Form3: With supports overhang printed just fine.

Clearance:

The test pieces were printed with support.

LeapFrog Creatr HS: 0.1 and 0.2 clearance between parts was too small; the pieces are not moving. Other c.

Raise 3D pro2: Printing was failed and the result is unclear.

Formlabs Form3: Only parts with 0.4, 0.3, 0.2 and 0.1 clearance are not moving, others are moving freely.
