Why is CLIP so much faster than SLA?

Stereolithography produces parts by projecting ultraviolet light on the top of a vat of liquid photopolymer, causing it to harden. CLIP produces parts by projecting ultraviolet light through the bottom of a vat of liquid photopolymer, causing it to…

Is PLA filament conductive?

I am planing on printing something that will make contact with PCB boards. The print will be most likely to be in PLA. I don't want to fry the PCB board so I want to know if 3D printed PLA objects are conductive. I googled and found out about…

Printing Plastic Replacement Parts

On a number of occasions I've broken small plastic parts that are nearly impossible to replace but could easily be 3-D printed. The latest such mishap is the volume knob on the factory-installed radio on my car. I have little experience in 3D…

Comparative design methods for joints that will be joined together

I want to 3D-print some parts that will be later joined together along a seam. When modeling these separate parts, what are some methods that work well with 3D-printed pieces? For example, if I were doing wood working, I might choose dowel and pin…

PLA and bed heating?

I've read different things about PLA and heat-bed. Some say it is not needed, others recommend 60-70°C, but not for the first layers. For larger objects I often have the problem that the object does not stick to the blue-painters-tape-covered…

Reducing amount of material

Just started doing some design. First project was a replacement handle for my angle grinder, so basically a hollow cylinder. I want to reduce the amount of material used in the print. I could sit here and punch holes through the handle with a…

Extruder clicks

I have Prusa i3 derivative with MK8 extruder and Marlin 1.1RC8 as firmware. I already reduced the default speeds as well as the accelerations. But sometimes when trying to print with BQ PLA filament (220°C), mostly during filling areas, my extruder…

Second layer: gaps, poor adhesion - why?

I'm seeing the following pattern on my Prusa clone: The first layer prints OK, layer adhesion to the bed is good. The second layer shows the weird gaps. On larger pieces, or with an increased feed rate, it sometimes gets so bad that parts of the…

E3D Thermistor Alternative

E3D hotends use a thermistor whose legs are insulated with glass fiber sleeving and clamped down with a screw and washer: This solution enables the printing of high temperature materials, but it's a bit fragile and after reassembling the hotend a…

Troubleshooting poor adhesion at the edge of the bed

I've been printing for a week now on my new printer and have been getting great results, including great adhesion. However, most of my prints have had a fairly small footprint. Now, I'm stepping up the types of items I'm printing, and I've started…

Heated bed - what are the benefits? Why use one?

When using a heated bed with your printer, I have seen claims of running temperatures of 90c throughout the print. That seems like a fairly high power use to keep a large slab of, say, aluminium at 90c for long print times (ie multiple hours). Is…

Does the layer thickness have any effect of the strength of the 3D printed object?

Is a 100 micron layer thickness object stronger than 300 micron layer thickness 3D printed object? Are there any rules to follow? Filament type - PLA

Is there a way to save a multi part print if one fails?

I'm printing 6 separate parts in one go, after 4 hours of printing one part failed, but the other 5 are printing nicely. Is there a way to prevent the print from printing the failed part and continue printing the other 5 parts. I'm using Cura and an…

How to 3D Print 5-pointed star object that doesn't have flat bottom and hole in the middle?

I'm new to 3D Printing. I've created this star from Blender3d. As far as I know, most printers require a flat bottom. As you can see (blue line is Z-axis, red line is X-axis, green line Y-axis), the star doesn't have any flat sides or…
